The paper introduces two decoding techniques based on grouping for symbol flipping non-
binary LDPC codes. Firstly, a new technique of adaptive grouping of variable nodes in each …

This paper introduces an adaptive technique for grouping variable nodes in decoding non-
binary LDPC codes that involve symbol flipping. The technique considers both the individual …

Traditional cooperative wireless networks suffer from error propagation to the destination in
poor channel conditions. The incorrect decoding at the relay and low signalto-noise ratio …
