Polar Coded Cooperative Differential Spatial Modulation Based on Plotkin Construction and Quasi-Uniform Puncturing

Coded-cooperation combines virtual MIMO transmission and channel coding to achieve forward error correction while achieving diversity gain. It is a promising technology in 5G communications. The polar code the only that can theoretically Shannon limit transmission, which make it preferred cooperative communication. In this paper, we proposed new wireless communication scheme, coded spatial modulation schemes based on Plotkin construction Quasi-uniform puncturing (QUP). First, adopt inverted codeword of get cooperation method, offer significant improvement performance under fading channels. We analyze decoding characteristics codewords then introduces QUP method improve benefits. At same time, extend scheme with differential for schemes. coded-cooperation outperforms its non-cooperative counterpart identical conditions, as expected. Monte Carlo simulated results show outperform their corresponding schemes, by gain 2.5 dB 1024 length 0.25 rate conditions.
