摘要
针对发射天线数可变的扩展空间调制技术(Extended Spatial Modulation,ESM)提出了相应的低复杂度检测算法。传统的空间调制技术(Spatial Modulation,SM)将信息调制在发射的天线上,但是在一个符号周期内活跃的天线数为常数。而ESM允许在不同符号周期以不同数目的发射天线进行组合,不仅能够承载更多信息,同时对发射的天线也有了更多优选的空间,但是传统的检测算法在发射天线数固定时才能正常使用,针对ESM的特殊情况提出了阈值法检测天线,并通过数值实验给出了性能分析。
A low complexity detection scheme for extended spatial modulation （ESM） is proposed in this paper. Extended spatial modulation is a novel spatial modulation design where the number of active transmit antennas can be various, which boosts the data rate as more data bits can be modulated per symbol period. However traditional low complexity detection algorithms are only well performed when the number of active transmit antennas is fixed and known. A thresholding detection algorithm is proposed in this paper to solve this problem. Numerical experiments are performed for performance evalua- tion.
