一种采用坐标交织空时编码的空间调制方案
Coordinate interleaved space time coded spatial modulation scheme
摘要
Abstract
Based on Space Time Coding(STC) from Coordinate Interleaved Orthogonal Designs(CIOD), a novel Spatial Modulation (SM) scheme for 4 transmit antennas is presented. Compared with conventional SM, the novel scheme can not only improve the spectral efficiency of wireless communication system by using the transmit antenna number to carry information, but also achieve partial diversity gain by using STC. The use of conditional Maximum-Likelihood (ML) algorithm at the receiver reduces the decoding complexity effectively. The Bit Error Rate perfor-mances(BER) of the proposed scheme, SM and Space-Time Block Codes(STBC) over independent and correlated channel are presented. The simulation results show that the BER performance of the proposed scheme is better than that of conventional STBC and SM.关键词
