چکیده
In this letter, we propose a layered decoding algorithm for protograph-based low-density parity-check Hadamard codes (PLDPC-HCs), which have been shown to be ultimate-Shannon-limit approaching. Compared with the standard algorithm, improves convergence rate by about two times. At bit error of 2.0×10 -5 , decoder using 20 iterations shows very small degradation 0.03 dB compared 40 iterations. Moreover, 21 same performance as 41

Iterative reliability-based decoding of low-density parity check codes
In this paper, reliability based decoding is combined with belief propagation (BP) decoding for low-density parity check (LDPC) codes. At each iteration, the soft output values delivered by the BP algorithm are used as reliability values to perform reduced complexity soft decision decoding of the code considered. This approach allows to bridge the error performance gap between belief propagatio...
متن کاملEarly Decision Decoding Methods for Low-Density Parity-Check Codes
Low-density parity-check codes have recently received extensive attention as a forward error correction scheme in a wide area of applications. The decoding algorithm is inherently parallelizable, allowing communication at high speeds. One of the main disadvantages, however, is large memory requirements for interim storing of decoding data. In this paper, we investigate a modification to the dec...
متن کاملImproved Layered Min-Sum Decoding Algorithm for Low Density Parity Check Codes
In this paper, an improved layered min-sum (ILMS) algorithm is proposed for the decoding of lowdensity parity-check (LDPC) codes. The proposed method speeds up the decoding by slightly amplifying the message update from check node to variable node. Simulations and analytical results show that compared with the standard layered min-sum decoding algorithm, the proposed scheme may reduce the numbe...
متن کاملPerformance analysis of protograph-based low-density parity-check codes with spatial diversity
In wireless communications, spatial diversity techniques, such as space-time block code and single-input multipleoutput (SIMO), are employed to strengthen the robustness of the transmitted signal against channel fading. This article studies the performance of protograph-based low-density parity-check (LDPC) codes with receive antenna diversity. The authors first propose a modified version of th...
متن کاملIterative Decoding of Low-Density Parity Check Codes (A Survey)
Much progress has been made on decoding algorithms for error-correcting codes in the last decade. In this article, we give an introduction to some fundamental results on iterative, message-passing algorithms for low-density parity check codes. For certain important stochastic channels, this line of work has enabled getting very close to Shannon capacity with algorithms that are extremely effici...
