LDPC and RS codes are two common error correcting codes,which have been widely used in deep space communication.This paper investigates the performance comparisons between short LDPC and RS codes in AWGN channel based on BP algorithm.Both of the two linear block codes have same code length and code rate.The short codes used the LLR belief propagation algorithm and reed-solomon codes used the adaptive BP algorithm.Simulation results show that under the same conditions,short LDPC codes demonstrate better decoding performance than RS codes.
