LDPC
LDPC码是通过校验矩阵定义的一类线性码,为使译码可行,在码长较长时需要校验矩阵满足“稀疏性”,即校验矩阵中1的密度比较低,也就是要求校验矩阵中1的个数远小于0的个数,并且码长越长,密度就要越低。
(LDPC Coding with PSK modulation in Rayleigh fading channel
Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements.
In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.
Please feel free to contact me and let me know your comments.
