Abstract:

This article discusses the concept of CAN protocol and its implementation in verilog language. Initially the CAN protocol description is given in brief with the block diagram, later its design, implementation in verilog code is presented. The CAN transmission (Tx) data Frame is realized using verilog code, this is achieved by defining individual sub-blocks verilog codes and combining these to get the CAN transmission of data frame. In the year 1986, CAN data link layer protocol was introduced in SAE conference. In 1993, CAN protocol and high speed physical layer were internationally accredited as ISO 11898. As on today it has 11898-1 to 4 standard documents. The CAN 1.0, 2.0 versions were initially had fixed data rate for the entire frame. In 2012, CAN-FD (Flexible data rate) protocol was introduced. This will allow data phase a second higher bit rate, along with this restriction of 8 bytes is extended up to 64 bytes.In this paper CAN Tx data frame is realized using Xilinx 14.7 version using verilog language.

Abstract:

<p>High level of security is essential in wireless 5G communications. The last few years there has been an increase in research interest in the potential of the radio channel’s physical properties to provide communications security. These research efforts investigate fading, interference, and path diversity to develop security techniques for implementation in 5G New Radio (NR). In this paper, we propose a collaborative scheme to existing physical layer security schemes, taking advantage of the characteristics of the OFDM technique. An OFDM symbol includes the pilot subcarriers, typically essential for the pilot channel estimation process performed at the legitimate receiver. In this work we propose the positions of the subcarriers to change on every OFDM symbol following a probability distribution known only to the legitimate transmitter and legitimate receiver. An eavesdropper, does not have access to the information of the pilot subcarriers positions so, it performs blind channel estimation. The theoretical analysis is based on the information theoretic problem formulation and is confirmed by simulations. The performance metrics used are the secrecy capacity and the outage probability. The proposed scheme is very simple and robust, strengthening security in multimedia applications.</p>

Abstract:

LoRa Wide Area Networks (LoRaWAN) can provide a connectivity service to Internet of Things (IoT) for an extremely long run-time and with low power consumption. As the LoRaWAN is extensively applied to various IoT scenarios, LoRaWAN solutions face a flexibility issue in terms of inter-operating with various kinds of LoRa modem hardware and protocol scenarios. In this regard, we design a unified protocol architecture for LoRaWAN physical layer, which can flexibly correspond to various deployment and operational cases. The new protocol architecture includes a hardware abstraction sub-layer, which contains generalized handlers for configuring various kinds of the LoRa modem, and a physical procedure sub-layer that structurally models the physical layer procedures of the LoRaWAN based on Finite State Machine(FSM). We illustrate the flexibility of the new protocol architecture by implementing an extensive feature that enhances the packet reception ratio based on the status of preamble detection. For evaluating the new protocol architecture, we implement the LoRaWAN physical layer protocol on real-time embedded systems and conduct experiments. The experimental results show that the proposed protocol robustly transmits and receives packets and generates little amount of additional burden compared with the conventional open source protocol provided by SemTech.

Abstract:

This paper presents a video transmission system for scalable High-Efficiency Video Coding (HEVC) videos using a 4G standard’s physical layer. SHVC, the scalable HEVC is used to compress the different layers of videos into binary files. The resultant binary files are easily transportable over any network thus solving many issues mainly related to videos with high resolutions. Three scenarios are studied and simulated at first, namely, Single Input Single Output (SISO), Multiple Input Single Output (MISO) and MIMO. Since the MIMO scenario offers the best results, it is considered in the implementation of the system on Field Programmable Gate Array (FPGA) using Xilinx System Generator (XSG). A Simulink model is developed under Matlab to simulate the video transmission scenarios using the WIMAX physical layer. Then, the MIMO system is implemented using a Zed-Board to co-simulate the video transmission in real-time and which allows a successful reception of the video sequences.

Abstract:

Machine learning (ML) has been broadly connected to the upper layers of communication systems for different purposes, for example, arrangement of cognitive radio and communication network. Nevertheless, its application to the physical layer is hindered by complex channel conditions and constrained learning capacity of regular ML algorithms. Deep learning (DL) has been as of late connected for some fields, for example, computer vision and normal dialect preparing, given its expressive limit and advantageous enhancement ability. This paper describes about a novel use of DL for the physical layer. By deciphering a communication system as an auto encoder, we build up an essential better approach to consider communication system outline as a conclusion to-end reproduction undertaking that tries to together enhance transmitter and receiver in a solitary procedure. This DL based technique demonstrates promising execution change than traditional communication system.

Abstract:

We present a joint scheme that combines both error correction and security at the physical layer. In conventional communication systems, error correction is carried out at the physical layer while data security is performed at an upper layer. As a result, these steps are done as separate steps. However there has been a lot of interest in providing security at the physical layer. As a result, as opposed to the conventional system, we present a scheme that combines error correction and data security as one unit so that both encryption and encoding could be carried out at the physical layer. Hence, in this paper, we present an Error Correction-Based Cipher (ECBC) that combines error correction and encryption/decryption in a single step. Encrypting and encoding or decoding and decrypting in a single step will lead to a faster and more efficient implementation. One of the challenges of using previous joint schemes in a communications channel is that there is a tradeoff between data reliability and security. However, in ECBC, there is no tradeoff between reliability and security. Errors introduced at the transmitter for randomization are removed at the receiver. Hence ECBC can utilize its full capacity to correct channel errors. We show the result of randomization test on ECBC and its security against conventional attacks. We also present the nonpipelined and pipelined hardware architecture of ECBC, and the result of the FPGA implementation of the ECBC encryption. We also compare these results with non-ECBC schemes.

Abstract:

It has been proved that Physical-layer Network Coding (PNC) can boost the system throughput obviously and decrease the error rate by reducing the time slots of inter-communication,which makes signal processing efficient and reliable.Coded Modulation (CM) considers coding and modulation as a whole,which makes coding and modulation effective without decreasing system transmission rate ,to guarantee bandwith efficiency.In this paper,the basic idea of the CM and its implementation are introduced.We analyze the effect of the combination of CM and PNC for communication system performance,which provide the foundation for future research.

Abstract:

AbstractIndustry 4.0 is referred as the fourth industrial revolution that represents the information intensive transformation of industrial automation and manufacturing processes. Cyber-physical systems (CPS) are building blocks in Industry 4.0 and part of the Industry 4.0 vision. This paper presents a cyber-physical platform development and implementation strategy for Industry 4.0 applications. It has been considered a cyber-physical platform model (CPP) built upon hardware reconfigurable technology based on a Field Programmable Gate Array (FPGA) processor framework. The development strategy exploits the full benefits enabled by reconfigurable hardware, such as scalability of complex systems, platform-based design approach, adaptive processing, real-time constrains management, or high performance prototyping capabilities. The implemented experimental setup also combines major advantages of both the hardware and software platform-based design trends in Industry 4.0. In this endeavor, the used software toolkit comprises the entire system complexity as a high performance integration layer. The presented design method and implementation strategy can serve as rough orientation for future CPS research and development activities.

Abstract:

The large bandwidth of the 60 GHz frequency band enables wireless short-range applications with data rates of several Gbit/s. The German project EASY-A has focused on early prototype implementations for selected applications, although no generally accepted 60 GHz standard has been available at the time. The implementations are based on application-oriented physical layer designs and link-budget investigations that account for the scenario-specific channel characteristics and for different integration technologies. This paper discusses the results of these investigations and details the hardware implementation of the digital baseband processing that relies on considerable parallelization. The link-budget results show that SiGe technology allows for 1 Gbit/s at a range of 3.5 m in non-line-of-sight environments, while up to 10 Gbit/s are feasible at more than 1 m in case of strong line of sight.

Abstract:

Referred to the protocol specification of DeviceNet, the hardware structure was set up by analysis of the physical layer and data link layer. Then it emphasized the software implementation procedure of the communication between master and slave from the view of application layer. With the software and hardware design method, a group 2 only communication node based on DeviceNet was designed through the platform of CAN controller SJA1000. Finally both IXXAT Corporation’s DNSDT protocol analysis software and RockWell’s master device were used to test the slave node. And the experimental data is detailed to verify that this slave node can fully meet the requirements specification of DeviceNet.

Abstract:

LTE is accepted worldwide as the Long Term Evolution Perspective for todays 3G and 4G networks. Cell search time synchronization is an important physical layer procedure by which a user equipment (UE) acquires synchronization with a cell and detects the physical layer cell ID of that cell. Timing synchronization is consisted of the symbol timing synchronization and frame synchronization. This paper supplies the introduction of synchronization signals, presents the detection method, and analyzes the design based on FPGA platform and finally simulated on the Modelsim 6.5 and implemented in Xilinx Virtex-6 kit.

Abstract:

Digital twin has aroused extensive attention of international academia and industry to support future interaction with the physical and virtual world. Although the research and application of digital twin spring up continuously, the concept in the manufacturing domain remains in its infancy. In this context, this paper first reviews the applications of digital twins for intelligent manufacturing. Then it presents an innovative application framework of a digital twin-driven ship intelligent manufacturing system and analyzes its operation mechanism. The application framework of a digital twin-driven ship intelligent manufacturing system mainly includes five parts: the physical layer, model layer, data layer, system layer, and application layer. Finally, key enabling techniques, as well as a case study in a pipe machining production line, are constructed and studied to validate the proposed approach. Meanwhile, system design and implementation, the twin modeling construction, application process, and implementation effect of the pipe machining production line are described in detail to provide a reference for enterprises.

Abstract:

Due to the fourth industrial revolution, manufacturing companies are looking to implement digital twins in their factories to be more competitive. However, the implementation of digital twins in manufacturing systems is a complex task. Factories need a framework that can guide them in the development of digital twins. Hence, this article proposes a small-scale digital twin implementation framework for manufacturing systems. To build this framework, the authors gathered several concepts from the literature and designed a digital twin subsystem model using a model-based systems engineering (MBSE) approach and the systems engineering “Vee” model. The systems modelling defines the digital twin components, functionalities, and structure. The authors distribute most of these concepts throughout the framework configuration and some concepts next to this general configuration. This configuration presents three spaces: physical, virtual, and information. The physical space presents a physical layer and a perception layer. The information space has a single layer called middleware. Finally, the virtual space presents two layers: application and model. In addition to these layers, this framework includes other concepts such as digital thread, data, ontology, and enabling technologies. This framework could help researchers and practitioners to learn more about digital twins and apply it to different domains.

Abstract:

Cognitive radio technology has received wide attention for its ability to sense and use idle frequency. IEEE 802.22 WRAN, the first to follow the standard in cognitive radio technology, is featured by spectrum sensing and wireless data transmission. As far as wireless transmission is concerned, the availability and implementation of a mature and robust physical layer algorithm are essential to high performance. For the physical layer of WRAN using OFDMA technology, this paper proposes a synchronization algorithm and at the same time provides a public platform for the improvement and verification of that new algorithm. The simulation results show that the performance of the platform is highly close to the theoretical value.
