摘要：
Nonbinary LDPC codes demonstrated excellent performance. However, how to reduce the decoding complexity for such codes, without performance degradation is still a problem to be solved. In this paper, the bit-flipping method is introduced into the standard Fourier transform decoding algorithm for decoding nonbinary LDPC codes. Simulation results show that the proposed method gains better BER performance with efficiently reduce of the decoding computation complexity in high E-b/N-0 regions.
