摘要
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 algo-rithms reduce the computational complexity meanwhile achieving optimal performance.关键词
