摘要

空间调制(Spatial Modulation

SM)是一种特殊的多天线传输技术

利用发送天线索引和发送的符号共同传递信息.为了获得发送分集增益

人们将天线选择技术应用到SM系统中

提高SM系统解调性能.在天线选择技术中

最大-最小欧式距离(Euclidean Distance Antenna Selection

EDAS)准则应用较为广泛

但是它的全搜索求解方法复杂度高

限制了其应用.为此

本文利用空间调制系统和调制符号本身的特性

给出了两种低复杂度的最优天线选择算法

并通过计算机仿真和复杂度分析

表明了该算法的有效性和最优性.

Abstract

Spatial modulation (SM) is a special multi-antenna transmission technology

where the transmit antenna index is exploited to convey information except for modulation signals.In order to obtain transmit-diversity gains

antenna selection technology is introduced in SM systems to increase its demodulation performance.In antenna selection technology

Euclidean distance antenna selection (EDAS) is widely applied.However

its exhaust-search detection has extremely high complexity

which limits its application.Thus

exploiting the characteristics of modulation symbols and 2-D quantization

two low-complexity and optimal antenna selection algorithms are proposed.The simulation results show that the proposed algorithms reduce the computational complexity meanwhile achieving optimal performance.
