matlab codes for ldpc


Here are some codes I developed for LDPC. All of them are for hard decision bit-flipping algorithm.

Hope this helps.

I will be updating the codes from time to time.

belief propagation in matlab


Most of the matlab codes fir LDPC on the website are designed for Gaussian channels.


I am confused if it is possible to use same code over some fading channels as well ?

If no, than what should be changed so that the code for AWGN can be used over fading channels like Rayleigh.

please suggest ..

LDPC software (Matlab)


can anybody help me out here...

we can generate a Fixed size LDPC matrix using matlab very easily e.g 32400*64800.. but what if i want to change the dim of my Matrix.. for say 100*200.. anybody any idea.

sparse matrix helps a bit, but Matlab gives an errror saying that it has to b something like defined over GF(2)....
driving me crazy... anyone give me the idea and code or anything......Crying or Very sadCrying or Very sadCrying or Very sad

thanks always..
