摘要:

这封信提出了一个全面的框架,分析的渐近误差性能的多输入多输出(MIMO)无线系统采用空间调制(SM)与最大似然检测和完美的信道状态信息。推导了MIMO SM系统的分集增益和编码增益的一般解析表达式,揭示了MIMO SM系统的基本特性。所提出的分析可以用来获得封闭形式的广义衰落下的MIMO SM系统的平均误比特概率(ABEP)的上限,成为渐近紧在高信噪比(SNR)区域。

英文摘要:

This letter presents a comprehensive framework analyzing the asymptotic error performance of a multiple-input-multiple-output (MIMO) wireless system employing spatial modulation (SM) with maximum likelihood detection and perfect channel state information. Generic analytical expressions for the diversity and coding gains are deduced that reveal fundamental properties of MIMO SM systems. The presented analysis can be used to obtain closed-form upper bounds for the average bit error probability (ABEP) of MIMO SM systems under generalized fading which become asymptotically tight in the high signal-to-noise ratio (SNR) region.
