基于空间调制的二维空时极化编码技术研究
Research on Spatiotemporal 2-D Polarization Coding Technology Based on Spatial Modulation
摘要
Abstract
This paper addresses the limited decoding performance of spatial modulation(SM)systems with short codes,and proposes a two-dimensional polar-coded spatial modulation(2D-PC-SM)system based on two-dimensional po-lar space-time coding.Unlike the one-dimensional polar-coded spatial modulation(1D-PC-SM)scheme,which encodes on-ly in the time domain,the proposed scheme further introduces spatial domain encoding to fully exploit the spatial dimen-sions provided by massive antenna arrays.Source information is jointly encoded in both the time domain and the spatial do-main to generate a two-dimensional codeword matrix,which is then transmitted through spatial modulation mapping,there-by improving transmission reliability in short-code scenarios.At the receiver side,leveraging the sparsity of the spatial mod-ulation symbols after space-time coding,detection and decoding receivers based on orthogonal matching pursuit(OMP)and approximate message passing(AMP)are proposed.Simulation results demonstrate that the decoding performance of the proposed 2D-PC-SM-AMP is within 0.1 dB of the one-dimensional coded system with a maximum likelihood(ML)receiv-er.Meanwhile,compared to minimum mean square error(MMSE)detection,the OMP-and AMP-based detection and de-coding receivers significantly reduce computational complexity while achieving a 2 dB decoding performance gain.关键词
