Description: Low Density Parity Check (LDPC) codes simulation C program. This program is developed by Seishi Takamura in Stanford University. This program can realized the simulation of ber performance of regular LDPC codes. The code structure is defined by the*.txt file including the check node degree, variable node degree and the connection indices between the nodes in the bipartite graph. If you want to simulate LDPC codes with other parameters, you can only modify this input .txt file. I have tested this program and the logic is correct and performance is also accurate in the Bit error rate. In addition, the syntax of this program is so easy to learn. Generally speaking, it is a very good example for the rookie people working in the channel coding area.
