Abstract:
A new technique of using Optical Time Domain Reflectometry (OTDR) to detect the reflected power of FBG sensing array was researched systematically. The theoretical model between the reflected power detected by OTDR and the reflected wavelength of FBG was established by analyzing, and consequently the selection rule of FBG wavelength in OTDR detection system was proposed. Moreover, experiments about multi-combination of FBGs with high reflectivity were carried out. The cause of dummy peak and resonance peak in OTDR test curves were analyzed, and meanwhile the selection basis of FBG reflectivity was also given. Based on time division multiplexing theory, detecting low-reflectivity FBG by OTDR can increase the FBG multiplexing number greatly, which has wide prospect to be applied in FBG array detection.

Abstract:
To achieve multi-gas measurements of quartz-enhanced photoacoustic spectroscopy (QEPAS) sensors under a frequency-division multiplexing mode with a narrow modulation frequency interval, we report a frequency-domain detection method. A CH4 absorption line at 1653.72 nm and a CO2 absorption line at 2004.02 nm were investigated in this experiment. A modulation frequency interval of as narrow as 0.6 Hz for CH4 and CO2 detection was achieved. Frequency-domain 2f signals were obtained with a resolution of 0.125 Hz using a real-time frequency analyzer. With the multiple linear regressions of the frequency-domain 2f signals of various gas mixtures, small deviations within 2.5% and good linear relationships for gas detection were observed under the frequency-division multiplexing mode. Detection limits of 0.6 ppm for CH4 and 2.9 ppm for CO2 were simultaneously obtained. With the 0.6-Hz interval, the amplitudes of QEPAS signals will increase substantially since the modulation frequencies are closer to the resonant frequency of a QTF. Furthermore, the frequency-domain detection method with a narrow interval can realize precise gas measurements of more species with more lasers operating under the frequency-division multiplexing mode. Additionally, this method, with a narrow interval of modulation frequencies, can also realize frequency-division multiplexing detection for QEPAS sensors under low pressure despite the ultra-narrow bandwidth of the QTF.

Abstract:
Optical waveguides simultaneously transport light at different colors, forming the basis of fiber-optic telecommunication networks that shuttle data in dozens of spectrally separated channels. Here, we reimagine this wavelength division multiplexing (WDM) paradigm in a novel context––the differentiated detection and identification of single influenza viruses on a chip. We use a single multimode interference (MMI) waveguide to create wavelength-dependent spot patterns across the entire visible spectrum and enable multiplexed single biomolecule detection on an optofluidic chip. Each target is identified by its time-dependent fluorescence signal without the need for spectral demultiplexing upon detection. We demonstrate detection of individual fluorescently labeled virus particles of three influenza A subtypes in two implementations: labeling of each virus using three different colors and two-color combinatorial labeling. By extending combinatorial multiplexing to three or more colors, MMI-based WDM provides the multiplexing power required for differentiated clinical tests and the growing field of personalized medicine.

Abstract:
Multiple-antenna systems are a promising approach to increase the data rate of wireless communication systems. One efficient possibility is spatial multiplexing of the transmitted symbols over several antennas. Many different MIMO detector algorithms exist for this spatial multiplexing. The major difference between different MIMO detectors is the resulting communications performance and implementation complexity, respectively. Particularly closed-loop MIMO systems have attained a lot of attention in the last years. In a closed-loop system, reliability information is fed back from the channel decoder to the MIMO detector. In this paper, we derive a basic framework to compare different soft-input soft-output MIMO detectors in open- and closed-loop systems. Within this framework, we analyze a depth-first sphere detector and a breadth-first fixed effort detector for different application scenarios and their effects on area and energy efficiency on the whole system. We present all system components under open- and closed-loop system aspects and determine the overall implementation cost for changing an open-loop system in a closed-loop system.

Abstract:
Wireless communication companies require to use the frequency spectrum to operate. Both frequency licenses and infrastructure to reuse frequencies are costly resources subject to increasing demand. This work introduces a novel multiplexing method that saves spectrum called Spectral Shape Division Multiplexing (SSDM). Under certain configurations, SSDM displays higher flexibility and throughput than other spectrally efficient methods. SSDM defines the structure of a wireless multi-carrier by software. It is similar to Orthogonal Frequency Division Multiplexing (OFDM) in that both use overlapped sub-carriers to make efficient use of allocated spectrum. However, SSDM has several advantages. Where OFDM organizes sub-carriers orthogonally, SSDM allows arbitrary frequency steps enabling higher spectral efficiency. Similarly, while OFDM and other spectrally efficient methods use sinusoidal pulse forms, SSDM can use non-standard pulses providing a greater control of the carrier. In this thesis, a SSDM transceiver is implemented to reduce the spectrum utilization. SSDM presents an increase in spectral efficiency of 20% average with respect to OFDM. The cost of this gain is higher computational speed and signal to noise ratio. The mathematical models and possible architecture for an SSDM system with sinusoidal pulses is developed. The modem is compared with other spectrally efficient methods. Similarly, the trade-offs between spectral efficiency, bit-error rates, dimension of the carrier and sub-carrier spacing are subject of analysis.

Abstract:
Abstract The development of wireless telecommunication systems has been rapid during the last two decades and the data rates as well as the quality of service (QoS) requirements are continuously growing. Multiple-input multiple-output (MIMO) techniques in combination with orthogonal frequency-division multiplexing (MIMO–OFDM) have been identified as a promising approach for high spectral efficiency wideband systems. The optimal detection method for a coded MIMO–OFDM system with spatial multiplexing (SM) is the maximum a posteriori (MAP) detector, which is often too complex for systems with high order modulation. Suboptimal linear detectors, such as the linear minimum mean square error (LMMSE) criterion based detection, offer low complexity solutions, but have poor performance in correlated fading channels. A list sphere detector (LSD) is a tree search based soft output detector that can be used to approximate the MAP detector with a lower computational complexity. The benefits of the more advanced detectors can be realized especially in a low SNR environment by, e.g., increasing the cell coverage. In this thesis, we consider the linear minimum mean square error (LMMSE) criterion based detectors and more advanced LSDs for detection of SM transmission. The LSD algorithms are not as such feasible for hardware implementation. Therefore, we identify the design choices that relate to the performance and implementation complexity of the LSD algorithms. We give guidelines to the LSD algorithm design and propose the proper trade-off solutions for practical wireless systems. The more stringent requirements call for further research on architectures and implementation. In particular, it is important to address the parallelism and pipelining factors in the architecture design to enable an optimal trade-off between used resources and operating speed. We design pipelined systolic array architecture for LMMSE detector algorithms and efficient architectures with given algorithm properties for the LSD algorithms. We consider the VLSI implementation of the algorithms to study the true performance and complexity. The designed architectures are implemented on a field programmable gate array (FPGA) chip and CMOS application specific integrated circuit (ASIC) technology. Finally, we present some measurement results with a hardware testbed to verify the performance of the considered algorithms
Tiivistelmä Langattoman tietoliikenteen kehitys on ollut nopeaa viimeisien vuosikymmenien aikana ja järjestelmiltä vaaditaan yhä suurempia datanopeuksia ja luotettavuutta. Multiple-input multiple-output (MIMO) tekniikka yhdistettynä monikantoaaltomodulointiin (MIMO-OFDM) on tunnistettu lupaavaksi järjestelmäksi, joka mahdollistaa tehokkaan taajuusalueen hyödyntämisen. Optimaalinen ilmaisumenetelmä tilakanavoituun (SM) ja koodattuun MIMO-OFDM järjestelmään on maximum a posteriori (MAP) ilmaisin, joka on tyypillisesti liian kompleksinen toteuttaa laajakaistajärjestelmissä, joissa käytetään korkean asteen modulointia. Alioptimaaliset lineaariset ilmaisimet, kuten pienimpään keskineliövirheeseen (LMMSE) perustuvat ilmaisimet, ovat suhteellisen yksinkertaisia toteuttaa nykyteknologialla, mutta niiden suorituskyky on varsin heikko korreloivassa radiokanavassa. Listapalloilmaisin (LSD) on puuhakualgoritmiin perustuva pehmeän ulostulon ilmaisin, joka pystyy jäljittelemään MAP ilmaisinta sitä pienemmällä kompleksisuudella. Kehittyneemmät ilmaisimet, kuten LSD, voivat parantaa langattoman verkon suorituskykyä erityisesti ympäristössä, jossa on matala signaalikohinasuhde, esimerkiksi mahdollistamalla suuremman toiminta-alueen. Tässä väitöskirjassa on tutkittu kahta LMMSE ilmaisinta ja kolmea LSD ilmaisinta SM lähetyksen ilmaisuun. Yleisesti LSD algoritmit eivät ole sellaisenaan toteutuskelpoisia kaupallisiin järjestelmiin. Väitöskirjassa on tämän vuoksi tutkittu LSD:n toteutukseen liittyviä haasteita ja toteutusmenetelmiä ja annetaan suosituksia LSD algorithmien suunnitteluun sekä ehdotetaan sopivia toteutuskompromisseja käytännön langattomiin järjestelmiin. Haastavammat suorituskyky- ja latenssivaatimukset edellyttävät lisätutkimuksia toteutusarkkitehtuureihin ja toteutuksiin. Erityisesti rinnakkaisten resurssien käyttö ja liukuhihnatekniikka toteutusarkkitehtuureissa mahdollistavat optimaalisen kompromissin löytämisen toteutuksessa käytettyjen resurssien ja laskentanopeuden väliltä. Väitöskirjassa suunnitellaan tehokkaat arkkitehtuurit tutkituille LMMSE ja LSD algoritmeille ottaen huomioon niiden ominaisuudet. Väitöskirjassa tutkitaan algoritmien toteutusta VLSI tekniikalla ja pyritään saamaan realistinen arvio algoritmien kompleksisuudesta ja suorituskyvystä. Algoritmeille suunnitellut arkkitehtuurit on toteutettu sekä FPGA piirille että erillisenä toteutuksena ASIC teknologialla. Väitöskirjassa esitetään myös testilaitteistolla tehtyjä mittaustuloksia ja varmistetaan toteutettujen algoritmien suorituskyky

Abstract:
Wavelength division multiplexing passive optical network (WDM-PON) can meet growing bandwidth demand in access network by providing high bandwidth to the end users. Failure in the access network is becoming critical as a large volume of traffic might be affected. Therefore, an effective supervision mechanism to detect and localize the fault is required to shorten the service interruption time. Meanwhile, open access provides a certain freedom for end users to choose the service and hence boosts competition among service/network providers. On the other hand, to offer open access in WDM-PON could result in a substantial change on architectural design, e.g., multiple feeder fibers (FFs) instead of a single one may be required to connect different service/network providers. Consequently, the traditional supervision mechanisms don’t work properly in open WDM-PON. To fill in this gap, several fault supervision mechanisms to support open access in WDMPON are proposed in this thesis. They can be applied to both disjoint and co-located FF layout where the choice of providers is done through wavelength selection. The feasibility of such solutions has been validated by evaluating transmission performance. We have carried out simulations in VPItransmissionMaker for different deployment scenarios. The results have confirmed that no significant degradation of the transmission performance is introduced by the proposed monitoring schemes compared to the benchmark, where no any fault supervision method is implemented.

Abstract:
This project focuses on wavelength division multiplexing passive optical network (WDM-PON) supervision using optical time domain reflectometer (OTDR) for detection and localization of any fault occurred in optical distribution network. The objective is to investigate the impact of OTDR monitoring signal on the data transmission in the WDM-PON based on wavelength re-use system, where the same wavelength is assigned for both upstream and downstream to each end user. Experimental validation has been carried out to measure three different schemes, i.e. back-to-back, WDM-PON with and without OTDR connection by using 1xN and NxN arrayed waveguide gratings. Furthermore, a comprehensive comparison has been made to trace out the effect of the monitoring signal which is transmitted together with the data through the implemented setup. Finally, the result has confirmed that the OTDR supervision signal does not affect the data transmission. The experiment has been carried out at Ericsson AB, Kista.

Abstract:
Optical coherent techniques are used to eliminate the power fading found in optical subcarrier multiplexed systems. In a double-side band optical subcarrier system the signal experiences a periodic power fading that is dependent on the fiber dispersion and subcarrier frequency. This power fading is manifested during the direct detection of the subcarrier system using a square-law photodetector. Using a modified optical local oscillator to coherently detect the subcarrier channel this power fading can be eliminated. An optical local oscillator is centered at the optical carrier in order to perform homodyne detection. However, the local oscillator is modulated by a term equal the subcarrier frequency of interest. This is then a dual-frequency optical local oscillator. By controlling the phases of the local oscillator and the local subcarrier oscillator independently in the homodyne detection scheme, both the phase error and power fading of the detected subcarrier channel can be eliminated. This technique also allows the subcarrier to be selected optically, before the optical-to-electrical conversion. Analytical and simulation results are given to show the benefits of optical coherent detection in double-sideband subcarrier systems. By eliminating the periodic power loss found in the double-sideband subcarrier system the signal becomes dispersion limited and not power limited. A comparison of double-sideband and single-sideband subcarrier systems is presented. Multiple subcarriers and subcarrier spacing are also investigated for both double sideband and single sideband subcarrier systems. Optical phase and modulator noise are also considered in the analysis and simulation of coherent detection using a dual frequency optical local oscillator. Since the implementation used to eliminate the power fading is a phase correction based process, the phase noise of both the source and local oscillator lasers must be considered and the technique compared to typical direct and coherent detection techniques. Also, the effects of modulator nonlinearity are simulated for multichannel subcarrier multiplexed systems and comparisons made between the performance of using the dual-frequency local oscillator and typical detection techniques. It is shown that the advantages of the dual-frequency LO are retained in the presence of both phase noise and modulator nonlinearity.

Abstract:
Multilayer networks are formed by several networks that interact with each other and co-evolve. Multilayer networks include social networks, financial markets, transportation systems, infrastructures and molecular networks and the brain. The multilayer structure of these networks strongly affects the properties of dynamical and stochastic processes defined on them, which can display unexpected characteristics. For example, interdependencies between different networks of a multilayer structure can cause cascades of failure events that can dramatically increase the fragility of these systems; spreading of diseases, opinions and ideas might take advantage of multilayer network topology and spread even when its single layers cannot sustain an epidemic when taken in isolation; diffusion on multilayer transportation networks can significantly speed up with respect to diffusion on single layers; finally, the interplay between multiplexity and controllability of multilayer networks is a problem with major consequences in financial, transportation, molecular biology and brain networks. This field is one of the most prosperous recent developments of Network Science and Data Science. Multilayer networks include multiplex networks, multi-slice temporal networks, networks of networks, interdependent networks. Multilayer networks are characterized by having a highly correlated multilayer network structure, providing a significant advantage for extracting information from them using multilayer network measures and centralities and community detection methods. The multilayer network dynamics (including percolation, epidemic spreading, diffusion, synchronization, game theory and control) is strongly affected by the multilayer network topology. This book will present a comprehensive account of this emerging field.

AbstractThe ASTEROID project developed a cross-layer fault-tolerance solution to provide reliable software execution on unreliable hardware under soft errors. The approach is based on replicated software execution with hardware support for error detection that exploits future many-core platforms to increase reliability without resorting to redundancy in hardware. This chapter gives an overview of ASTEROID and then focuses on the performance of replicated execution and the proposed replica-aware co-scheduling for mixed-criticality. The performance of systems with replicated execution strongly depends on the scheduling. Standard schedulers, such as Partitioned Strict Priority Preemptive (SPP) and Time-Division Multiplexing (TDM)-based ones, although widely employed, provide poor performance in face of replicated execution. By exploiting co-scheduling, the replica-aware co-scheduling is able to achieve superior performance.

Space-time block coding is a way of introducing multiplexing and diversity gain in wireless systems equipped with multiple antennas. There are several classes of codes tailored for different channel conditions. However, in almost all the cases, maximum likelihood detection is required to fully realize the diversity introduced. In this chapter, we present the fundamentals of space-time block coding, as well as introduce new codes with better performance. Additionally, we introduce the basic detection algorithms which can be used for detecting space-time block codes. Several low complexity pseudo-maximum likelihood algorithms will also be introduced and discussed.

Abstract:
Modulated signals used in communication systems exhibits cyclic periodicity. This is primarily due to sinusoidal product modulators, repeating preambles, coding and multiplexing in modern communication. This property of signals can be analyzed using cyclostationary analysis. SCF (Spectral correlation function) of cyclic autocorrelation (CAF) has unique features for different modulated signals and noise. Different techniques are applied to SCF for extracting features on the basis of which decision of detecting a signal or noise is made. In this chapter, study and analysis of different modulated signals used in satellite communication is presented using SCF. Also comparison of several signal detection techniques is provided on the basis of utilizing unique feature exhibit by a normalized vector calculated on SCF along frequency axis. Moreover a signal detection technique is also proposed which identifies the presence of a signal or noise in the analyzed data within the defined threshold limits.

The second part of the chapter discusses MXene synthesis and various protocols for modification of MXene making it a suitable matrix for immobilization of bioreceptors such as antibodies, DNA aptamers or DNA molecules. The final part of the chapter summarizes examples of MXene-based nanobiosensors developed using optical, electrochemical and nanomechanical transducing schemes. Operational characteristics of such devices such as sensitivity, limit of detection, assay time, assay reproducibility and potential for multiplexing are provided. In particular MXene-based nanobiosensors for detection of a number of cancer biomarkers are shown here.

Abstract:
In this letter, we proposed a simple balanced-detection reception scheme for the half-cycled single-sideband direct-detected optical orthogonal frequency division multiplexing (HSSB DD-OFDM) signal with decreased guard band. By employing this scheme, each entire OFDM symbol can be recovered perfectly, while the signal-to-signal beat interference (SSBI) can be eliminated, the guard band can be reduced greatly and the tolerance to phase noise induced inter-channel interference (PN-ICI) and potential benefit of low peak to average power (PAPR) are retained. The simulation results demonstrate that a 40 Gbps 16-QAM HSSB DD-OFDM signal was achieved successfully.
