Abstract:

In the letter, a system of continuous phase modulation (CPM) with threaded space time codes (TSTC) is proposed for multiple-input multiple-output systems. In the system, source bits are coded via outer coder of Reed Solomon (RS). The codeword of which is suitable for TSTC design. Then inner coder mainly converts binary symbols into M-ary symbols for purpose of CPM. At receiver, Joint soft decoding approach is considered. Finally simulation results are provided for VBLAST, DBLAST, and TSTC as comparison.

Abstract:

This paper examines the link between the design codes, good design and the prevention of field failures. There are many design codes for the fatigue design of welds. They contain many differences influenced by the history of particular industries. Engineering may not be well served by these codes since on one hand they are normally conservative, thus creating excessively heavy structures. On the other hand the design codes often do not include the most important factors in the life expectancy of a weld namely the weld procedure, the quality of the weld and environmental effects. The paper concludes that a thorough review and unification of the industry design codes is overdue. The issue of manufacture of welds has to be put at the centre of the consideration of fatigue design.

Abstract:

This correspondence presents a jointly designed quasicyclic (QC) low-density parity-check (LDPC) coded-relay cooperation with joint-iterative decoding in the destination node. Firstly, a design-theoretic construction of QC-LDPC codes based on a combinatoric design approach known as optical orthogonal codes (OOC) is presented. Proposed OOC-based construction gives three classes of binary QC-LDPC codes with no length-4 cycles by utilizing some known ingredients including binary matrix dispersion of elements of finite field, incidence matrices, and circulant decomposition. Secondly, the proposed OOC-based construction gives an effective method to jointly design length-4 cycles free QC-LDPC codes for coded-relay cooperation, where sum-product algorithm- (SPA-) based joint-iterative decoding is used to decode the corrupted sequences coming from the source or relay nodes in different time frames over constituent Rayleigh fading channels. Based on the theoretical analysis and simulation results, proposed QC-LDPC coded-relay cooperations outperform their competitors under same conditions over the Rayleigh fading channel with additive white Gaussian noise.

Abstract:

This survey paper provides fundamentals in the design of LDPC codes. To provide a target for the code designer, we first summarize the EXIT chart technique for determining(near-)optimal degree distributions for LDPC code ensembles. We also demonstrate the simplicity of representing codes by protographs and how this naturally leads to quasi-cyclic LDPC codes. The EXIT chart technique is then extended to the special case of protograph-based LDPC codes. Next, we present several design approaches for LDPC codes which incorporate one or more accumulators, including quasi-cyclic accumulatorbased codes. The second half the paper then surveys severalalgebraic LDPC code design techniques. First, codes based on finite geometries are discussed and then codes whose designs are based on Reed-Solomon codes are covered. The algebraic designs lead to cyclic, quasi-cyclic, and structured codes. The masking technique for converting regular quasi-cyclic LDPC codes to irregular codes is also presented. Some of these results and codes have not been presented elsewhere. The paper focuses on the binary-input AWGN channel (BI-AWGNC). However, as discussed in the paper, good BI-AWGNC codes tend to be universally good across many channels. Alternatively, the reader may treat this paper as a starting point for extensions to more advanced channels. The paper concludes with a brief discussion of open problems.

Abstract:

Low-density parity-check (LDPC) codes are known to be one of the best error-correction coding (ECC) schemes in terms of correction performance. They have been utilized in many advanced data communication standards for which the codecs are typically implemented in custom integrated circuits (ICs). In this paper, we present a research work that shows that the LDPC coding scheme can also be applied in a system characterized by highly limited computational resources. We present a microcontroller-based application of an efficient LDPC encoding algorithm with efficient usage of memory resources for the code-parity-check matrix and the storage of the results of auxiliary computations. The developed implementation is intended for an IoT-type system, in which a low-complexity network node device encodes messages transmitted to a gateway. We present how the classic Richardson–Urbanke algorithm can be decomposed for the QC-LDPC subclass into cyclic shifts and GF(2) additions, directly corresponding to the CPU instructions. The experimental results show a significant gain in terms of memory usage and decoding timing of the proposed method in comparison with encoding with the direct parity check matrix representation. We also provide experimental comparisons with other known block codes (RS and BCH) showing that the memory requirements are not greater than for standard block codes, while the encoding time is reduced, which enables the energy consumption reduction. At the same time, the error-correction performance gain of LDPC codes is greater than for the mentioned standard block codes.

Abstract:

TraceabilityCodes are CombinatorialObjects introduced by Chor, Fiat and Naor in 1994[7] to be used in traitor tracing to protect Digital Content. Frameproof Codes were given byBoneh and Shaw in 1994 to prevent privacy and gave the idea of c-secure codes withέ-error. Traceable Codes is a strong form of Frameproof Codes. Balanced Incomplete Block Design Codes in form of frameproof codes arealready available in literature [4]. Here in this paper we will define how Balanced Incomplete Block Designs can be used as Traceable Codes and in view of our paper[ ] we have relaxed these conditionsfor being Balanced Incomplete Block Designs to be traceable Code.

Abstract:

To meet the increasing demands for remote sensing, a number of radar systems using Linear Frequency Modulation (LFM) waveforms have been deployed, causing the problem of depleting frequency resources. To address this problem, several researchers have proposed the Spectrum Shared Radar System (SSRS) in which multiple radars share the same frequency band to transmit and receive their own signals. To mitigate the interferences caused by the signal transmission by other radars, SSRS employs orthogonal waveforms that inherit the orthogonality of the waveforms from orthogonal codes. However, the inherited orthogonality of the codes is significantly reduced when incorporating LFM waveforms with the codes. To solve this problem, in this paper, we propose a novel but simple scheme for generating a set of optimized coded LFM waveforms via new optimization framework. In the optimization framework, we minimize the weighted sum of autocorrelation sidelobe peaks (ASP) and cross-correlation peaks (CP) of the coded LFM waveforms to maximize the orthogonality of the waveforms. Through computer simulations, we show that the waveforms generated by the proposed scheme outperform the waveforms created by previous proposals in terms of ASP and CP.

Abstract:

We design a coded massive multiple-input multiple-output (MIMO) system using low-density parity-check (LDPC) codes and iterative joint detection and decoding (JDD) algorithm employing a low complexity detection. We introduce the factor graph representation of the LDPC coded massive MIMO system, based on which the message updating rule in the JDD is defined. We devise a tool for analyzing extrinsic information transfer (EXIT) characteristics of messages flowing in the JDD and the three-dimensional (3-D) EXIT chart provides a visualization of the JDD behavior. Based on the proposed 3-D EXIT analysis, we design jointly the degree distribution of irregular LDPC codes and the JDD strategy for the coded massive MIMO system. The JDD strategy was determined to achieve a higher error correction capability with a given amount of computational complexity. It was observed that the coded massive MIMO system equipped with the proposed LDPC codes and the proposed JDD strategy has lower bit error rate than conventional LDPC coded massive MIMO systems.

Abstract:

This article focus on the implementation of FEC part. The motivation of the design is that FEC is an effective tool to mitigate problems associated with OFDM which stem from multipath fading channel, high speed data rate. One of the key features of BCH codes is that during code design, there is a precise control over the number of symbol errors that are correctable by the code. BCH coder proccesses parralelly with high-speed operation. 8-bit parallel data input and output helps to maximize the throughput. DVB-T2 used LDPC coder, as inner codes with word length up to 64,800 bits, enabling significant proximity to Shannon limit. This encoder supports all code rates and both normal and short frames. Output of LDPC encoder is interleaved with bit interleaver. This project was fully optimized for speed and memory area, fully synchronized by using a single clock. The design was coded in VHDL, synthesized by using Xilinx ISE Design Suite 14.7. The design has been tested on development Kit NetFPGA-1G-CML of Digilent Corporation and the bit map was downloaded into Xilinx Kintex-7 XC7K325T-1FFG676, which is integrated on experimental transmitter system DVB-T2. This research product belong to program “Research of experimental testing of second generation digital terrestrial television broadcasting system DVB-T2” of Vietnamese Communications Television Development JSC.

Abstract:

Seismic codes include strict requirements for the design and construction of mid-rise reinforced concrete residential buildings. These requirements call for the symmetric and regular arrangement of the structural system, increased cross-sections for columns, and the introduction of shear walls to counteract the effects of lateral seismic loads. It is challenging for architects to reconcile the demands of these codes with the spatial arrangement and commercial appeal of their designs. This study argues that such reconciliation is possible through an architectural analysis. First, the effectiveness of applying the seismic design principles required by the codes is demonstrated with the comparative analysis of two finite element models. Then three pairs of architectural models, representing the most common floor plan arrangements for such buildings in Turkey, are architecturally analyzed before and after the application of seismic design principles in terms of floor area and access to view. The results demonstrate that within the context defined by the methodology of this study, considerable seismic achievement can be achieved in mid-rise reinforced concrete residential buildings by the application of relatively few, basic design features by the architects.

Abstract:

Building structures should correspond to the reliability requirements which are implemented with the help of design codes. The latter are based on the method of limit states. In order to simplify the verifications, the design codes often deliberately deviate from the scientifically based theoretical provisions of such fundamental disciplines as the theory of elasticity and the theory of plasticity, replacing them with the so-called working practices. The paper presents that there are inaccurately formulated recommendations in the design codes. The paper also specifies on some important problems that are not reflected in the design codes. This applies to the choice of failure probability values, the use of partial reliability factors, the calculation methodology in case of an emergency, the problems of using the results of nonlinear calculation, etc. The paper presents some considerations on these issues, with the main attention being paid to the analysis of the existing design tradition and guidance to unresolved issues. The problems of recommended reliability parameters, clarification of the limit state concepts, analysis of accidental situations, the safety factors values and possible relationship between the safety factors for load and the safety factors for materials, loads and load effects, vulnerability assessment as well as reliability of protected systems have been considered. The considerations presented by the paper give only a partial idea of the range of issues that arise when comparing working practices used in the design codes with the theoretical fundamentals they should correspond to. It should also be noted that the design codes do not provide any justifications for their recommendations. The presented paper can initiate a scientific discussion and be useful both for the developers of design codes and for the developers of software packages implemented the design codes.

Abstract:

Algebraic manipulation detection codes were introduced in 2008 to protect data against a special type of its modification – an algebraic manipulation. There are three classes of codes: weak, strong and stronger ones. Weak codes detect only weak algebraic manipulations, while strong and stronger are capable to detect both weak and strong manipulations. In this paper, a method to transform codes from weak to stronger is described resulting in a construction of generalized robust codes. The proposed construction forms the second known family of stronger AMD codes. Codes provide simple procedures of error detectiona and correction, and allow using multi-code codec design that makes it applicable in fault-tolerant computing, storage and cryptographic devices.

Abstract:

This work focuses on high-rate () moderate-length () low-density parity-check codes. High-rate codes allow to maintain good quality of the preliminary decisions that are used in carrier recovery, while a moderate code length allows to keep the latency low. The interleaver of the LDPC matrix that we consider is inspired to the DVB-S2 standard one. A novel approach for avoiding short cycles is analyzed. A modified BP decoding algorithm is applied in order to deal with longer cycles. Simulations and results for the AWGN channel are presented, both for BPSK signalling and for coded modulation based on the partition .

Abstract:

As in classical coding theory, turbo product codes (TPCs) through serially concatenated block codes can achieve approximatively Shannon capacity limit and have low decoding complexity. However, special requirements in the quantum setting severely limit the structures of turbo product codes (QTPCs). To design a good structure for QTPCs, we present a new construction of QTPCs with the interleaved serial concatenation of [Formula: see text]-type quantum convolutional codes (QCCs). First, [Formula: see text]-type QCCs are proposed by exploiting the theory of CSS-type quantum stabilizer codes and QCCs, and the description and the analysis of encoder circuit are greatly simplified in the form of Hadamard gates and C-NOT gates. Second, the interleaved coded matrix of QTPCs is derived by quantum permutation SWAP gate definition. Finally, we prove the corresponding relation on the minimum Hamming distance of QTPCs associated with classical TPCs, and describe the state diagram of encoder and decoder of QTPCs that have a highly regular structure and simple design idea.

Abstract:

Modern seismic building design codes tend to converge on issues of design methodology and the state-of-the-art. However, significant differences exist in basic provisions of various codes. This paper compares important provisions related to the seismic design of RC buildings in some of the major national seismic building codes viz. ASCE 7, Eurocode 8, NZS 1170.5, and IS 1893. Code provisions regarding the specification of hazard, site classification, design response spectrum, ductility classification, response reduction factors, and minimum design base shear are compared and their cumulative effect on design base shear is studied. The objective component of overstrength contributed by the material and load factors is considered to normalize the design base shear. It is observed that every code has merit over the other codes in some aspect. The presented discussion highlights the major areas of differences which need attention in the process of harmonization of different codes of the world.
