Abstract

A long Irregular LDPC code that performs at rates extremely close to the Shannon capacity has been taken. The code has carefully chosen degree patterns. Simulations has been done with Hard and Soft-decision decoding to compare the performance of this code with the rates 1/2 ,1/3, 1/4 ,2/3 ,2/5, 3/4, 3/5, 4/5, 5/6, 8/9 and 9/10 over various channels like AWGN channel, Rayleigh fading channel and Rician fading channel. The little dependence of BER performance on various channels is explored here along with the conjecture of the concept of computational cutoff rate that represents an upper limit on rate of transmission for practically instrumentable reliable communications.
