<FONT face=Verdana>To mitigate the problems of high computation complexity and deteriorated error correction performance in decoding Repeat-Accumulate (RA) codes with Belief Propagation (BP) and Min-Sum algorithms
the idea of Weighted Bit-Flipping (WBF) is applied to improve the BP algorithm. The improved BP decoding algorithm based on the WBF scheme is proposed for systematic RA codes. If decoding is failure in each iteration
bit flipping measure is to be taken according to specific rules in order to obtain legitimate code words. Simulation results demonstrate that the proposed algorithm can decrease the computation complexity effectively for such RA codes while maintaining the excellent error-correction performance.
