Low density parity check codes nowadays use in modern system due to their excellent performance. There are different message passing algorithm for LDPC codes to decode. In this paper, we have mention bit flip algorithm in brief and gave its bit error performance over AWGN channel via simulation result. For this communication, we use BPSK i.e. Binary phase shift keying digital modulation technique. This algorithm is based on binary decision message passing algorithm. This paper shows bit error performance of bit flip algorithm for different block lengths of LDPC code. The significance of showing bit error performance in this paper is that it shows how efficiently this algorithm works. We have also mention why BPSK modulation technique is more efficient than any other modulation technique.
