Review on: Iterative Decoding schemes of LDPC codes

Low-density parity-check (LDPC) code, a very promising near-optimal error correction code (ECC), is being widely considered in next generation industry standards. In this paper, two simple iterative low complexity algorithms for decoding LDPC codes have been explained. These algorithms are implemented using real additions only and also not dependent on power spectral density. Comparison of these algorithms with standard BP algorithm are explained. How these algorithms are useful for standards DVBS2, T2 and WiMAX are explained. In VLSI implementation these algorithms using shiftLDPC codes these algorithms reduces hardware
