论文摘要
拟议的研究对配备了最大比率组合方案的单输出多输出多输出多次无线通信系统的容量高阶统计进行了分析。假定使用具有相关主要成分的$κ-μ$褪色模型来描述传播多径通道。得出闭合形式和渐近表达式，并应用于最小容量可靠性的问题（由于通道波动，因此可能的速率恶化）和相应的信号噪声比分析。执行的计算机仿真，验证获得的表达式的正确性，以及具有相关阴影的广义$κ-μ$褪色通道，假定有几个特定的限制性简化案例：雷利，里奇亚和中an和nakagami-$ m $。结果表明，在比简化模型的值中实现了信噪比（达到最低容量可靠性），并且该最小值的绝对值可能比退化案例更小/更高，因为根据优势组件一步相关系数。
The proposed research performs an analysis of the capacity higher-order statistics for a single-input multiple-output multiantenna wireless communication system equipped with a maximum-ratio combining scheme. It was assumed that the propagation multipath channel is described with the $κ-μ$ fading model with the correlated dominant components. Closed-form and asymptotic expressions were derived and applied to the problem of minimum capacity reliability (due to channel fluctuations, thus possible rate deterioration) and corresponding signal-to-noise ratio analysis. The performed computer simulation, verifying the correctness of the obtained expressions, along with the generalized $κ-μ$ fading channel with correlated shadowing, assumed several specific limiting simplified cases: Rayleigh, Rician and Nakagami-$m$. It was shown that the signal-to-noise ratio (at which minimum capacity reliability is attained) is achieved at greater values than that of simplified models, and the absolute value of this minimum can be smaller/higher than for the degenerate cases depending on the dominant components one-step correlation coefficient.
