Abstract :
Generally, soft decoding of low-density parity-check codes can be implemented by iterative decoding based on belief propagation (BP) algorithm. In this paper, the BP algorithm is presented and derived in a way which differs from that by Gallager, which helps to understand iterative decoding of LDPC codes more clearly.
