I wrote a matlab code for obtaining BER of ldpc codes using sum product algorithm. But its BER performance is relatively close to uncoded BPSK. What can I do to change this? What should be the dimension of parity check matrix, number of iterations???
Questions: Range for noise power N0 when bit energy=1 using BPSK modulation? No'of iterations required for sum product algorit...
