Space-Time Block Coded Spatial Modulation Based on Golden Code

Abstract

In this paper, a new Space-Time Block Coded Spatial Modulation (SM) scheme based on the Golden Code, called the Golden Coded Spatial Modulation (GC-SM), is proposed and analyzed. This scheme still keeps some main benefits of the Golden Code by satisfying the non-vanishing Space Time Block Code (STBC) criteria. In the signal constellation domain, the GC-SM spectral efficiency is twice that of the STBC-SM. In addition, simulation and theoretical results show that the GC-SM performance surpasses several SM schemes at the same spectral efficiency and antenna configuration. Furthermore, we study the impact of channel spatial correlation on the GC-SM performance. Finally, the GC-SM detection complexity is studied and compared with the existing SM schemes.
