The system capacity is defined as the maximum possible transmission rate such that the probability of error is arbitrarily small. Initially, we assume that the channel matrix is not known at the transmitter, while it is perfectly known at the r

Matlab software that generates LDPC parity check matrix of rate 1/2 with the possibility of selecting the input output block dimension and performs BER evaluation of BPSK+LDPC transmission over AWGN channel.
