Abstract

Low density parity check (LDPC) codes have become very popular in recent times due to their capacity approaching performance and are considered in the next generation digital video broadcasting DVB-S2 standard. This paper presents few results and observations obtained when some of the existing decoding algorithms are studied in the context of the standardized codes. These results with further consolidation will facilitate to arrive at the right algorithm for decoder design
