研究了发射天线选择(TAS)-最大比合并(MRC)与中继和用户选择相结合的多输入多输出系统在非相同Nakagami衰落信道下的误码率(SER)。本文推导了该系统有效信噪比的精确累积密度函数。利用CDF，本文推导了在非相同Nakagami衰落信道下，采用M进制正交幅度调制的TAS-MRC在中继和用户选择情况下的精确闭合表达式，包括利用渐近分析来量化分集阶数。
We investigate the symbol error rate (SER) of a transmit antenna selection (TAS)-maximal ratio combining (MRC) with relay and user selection in multiple-input multiple-output systems over non-identical Nakagami fading channels. This letter derives the exact cumulative density function (cdf) of the effective signal-to-noise ratio for the proposed system. Using the cdf, this letter derives the exact closed-form expressions of the TAS-MRC with relay and user selection for the SER with M-ary quadrature amplitude modulation over non-identical Nakagami fading channels including quantification of the diversity order using asymptotic analysis.
