<br/><br/> New designing technique for different rates of low - density parity - check codes (LDPC) inBI - AWGN channel is presented to minimize the gap to shannon bound CPSO algorithm is applied on the variable and check node degree distribution in case of irregular LDPC codes adapted discrete FDEis used to calculate the threshold value
