An Improved Multi-bit Flipping Algorithm for LDPC Decoding
摘要
Abstract
The bit-flipping (BF) algorithm of low density parity check (LDPC) code has low computation complexity and great practicability.On the basis of studying simple BF, WBF and RRWBF, an improved BF algorithm is proposed on considering the reliability ratio and ahsolute value of symbol.The proposed algorithm flips more than one bit in each iteration.Simulation results indicate that compared with RRWBF, the error rate of the proposed algorithm with 5 dB is improved from 10-3 to 10-4.关键词
