| Abstract: | In this paper, the basic idea of hard-decoding algorism for LDPC codes is introduced and a kind of practically used computer simulation process is described. Then it analyses the error-performance and iteration times of decoding algorism for middle-sized random LDPC codes when different thresholds are chosen. |
