A new high performance LDPC code for DVB-S2 [PDF]
, 2006 In spite of their powerful error correcting capability, Low Density Parity Check codes (LDPC) have been ignored due to their high complexity. Around three decades after the invention of this code, researchers returned back their attention to it and tried

Iterative Code Acquisition for DS-UWB Downlink using Multiple-Component Decoders
, 2008 Iterative code acquisition schemes employing beneficially chosen higher-order generator polynomials and multiple-component decoders are analysed in terms of the correct detection probability of the direct sequence-ultra-wideband (DS-UWB) downlink.

Performance of LDPC Code Based D-BLAST System [PDF]
, 2003 In this paper, we derive a closed form of symbol error probability of low density parity check (LDPC) code based diagonal Bell laboratories layered space-time (DBLAST) system over independent fading channel, especially for low SNR case.

FPGA Implementation of Irregular LDPC Code Decoder
, 2006 LDPC(低密度奇偶校验码)是一种优秀的线性分组码,是目前距香农限最近的一类纠错编码。与Turbo码相比,LDPC码能得到更高的译码速度和更好的误码率性能,从而被认为是下一代通信系统和磁盘存储系统中备选的纠错编码。简要介绍了适于硬件实现的LDPC码译码算法,并基于软判决译码规则,使用Verilog硬件描述语言,在X ilinx V irtex2 6000 FPGA上实现了码率为1/2、帧长504bit的非规则LDPC码译码器。Low Density Parity Check(LDPC) code is ...
