摘要

空间复用辅助空间调制(SMx-SM)是一种通信技术，本质上结合了垂直贝尔实验室分层时空(V-BLAST)和空间调制(SM)的概念。本文构造了一种高速率空间复用辅助广义空间调制(SMx-GSM)方案，该方案保证了极低的检测复杂度。利用码本结构，可以设计出SMx-GSM方案中基于树搜索的MIMO检测器。仿真结果表明，该方法可以显著降低检测复杂度，使系统具有较高的检测速率，且误差性能非常接近最大似然(ML)检测器，尤其适用于具有大量激活发射天线的高速率大规模SMx- GSM系统。

A Low-Complexity High-Rate Spatial Multiplexing Aided Generalized Spatial Modulation Scheme

Spatial multiplexing aided spatial modulation (SMx-SM) is a communication technology which essentially combines the concepts of Vertical Bell Labs Layered SpaceTime (V-BLAST) and spatial modulation (SM). In this paper, we construct a high-rate spatial multiplexing aided generalized spatial modulation (SMx-GSM) scheme which guarantees a very low detection complexity. Benefiting from the codebook structure, a tree-search based MIMO detector for the SMx-GSM scheme can be devised. Simulation results show that the detection complexity can be significantly reduced, which makes a highrate system feasible, and an error performance which is very close to that of the maximum-likelihood (ML) detector can be achieved, especially for the case of a high-rate large-scale SMx- GSM system with a large number of activated transmit antennas.
