Low Complexity Decoding Algorithms for Rate Compatible Modulation

Rate compatible modulation (RCM) has high spectrum efficiency and achieves seamless and blind rate adaptation in wide range of channel conditions. However, due to many convolution operations at symbol nodes, the belief propagation decoding algorithm of RCM has a high level of computational complexit...
