Decoding of Decode and Forward (DF) Relay Protocol using Min-Sum Based Low Density Parity Check (LDPC) System

Decoding high complexity is a major issue to design decode and forward (DF) relay protocol. Thus, the establishment of low decoding system would beneficial assist This paper reviews existing methods for min-sum based LDPC as system. Reference lists chosen articles were further reviewed associated publications. introduces comprehensive model representing describing developed DF It consists number components: (1) encoder modulation at source node, (2) demodulation, decoding, encoding (3) demodulation destination node. also proposes new taxonomy techniques, highlights some most important components such data used, result performances profiles Variable Check Node (VCN) operation that have potential be used in Min-sum provide an objective measure best tradeoff between complexities process error performance, emerge cost-effective solution practical application.
