Publisher review:Girth 4 test for LDPC codes - We need to know that Girth 4 of H will lead to a poor BER performance. Recently, we find some published programs for the construction of LDPC codes have not concerned the Girth test problem, which will not the implementation of LDPC Codec to have good decoding BER. Thus, we publish a simple program to provide a tool for the girth 4 test of LDPC codes.Input a parity check matrix H with the format of the example in the program, the program can determine whether it has girth 4.
Girth 4 test for LDPC codes is a Matlab script for Communication Tools scripts design by Yang Xiao.
It runs on following operating system: Windows / Linux / Mac OS / BSD / Solaris.
