| Research Abstract |
Our results invented a method that gives the accurate word error rate of LDPCcodes over a binary symmetric channel. We applied our results to some examples, known as SFA LDPC codes and verified the validity of our method. We also investigated the structure of FA(2, P)-and(3, P) LDPC codes. Our result characterizes the weight distribution of these LDPC codes.
