Hi!

I need to simulate with Matlab a QPSK and 8PSK modulations using LDPC Coding. I need to obtain the theoricals graphs of the Eb/No and BER relationship for differents code rates and modulations (in fact, I need to obtain the graphs for Eb/No and BER relationship for a DVB-S2 system), but I can't find a BER formula for LDPC codes.

Thanks!
