| Abstract: | In order to compare the performance of nonbinary LDPC codes and binary LDPC codes.We do effective analysis from parity check matrix,Tanner graph and BP algorithm and do concrete Monte Carlo simulation.Then we come to a conclusion that the performance of nonbinary LDPC codes certainly outperforms the performance of binary LDPC codes in the same code length. |
