近年来，针对大规模单输入多输出系统，提出了一种简单的基于能量检测的非相干通信方案，通过对所有天线上接收信号能量进行平均来解码发送符号。在本文中，我们研究了相关瑞利衰落对上述系统性能的影响。具体来说，我们推导出的符号错误率，可达速率，中断概率的解析表达式。此外，这些表达式的渐近行为的制度，大量的接收天线，高信道相关性，和高信噪比的影响。分析结果表明，信道相关性的错误概率的不利影响，这可以归因于这样一个事实，即信道相关性减少了自由度。我们的分析还表明，信道相关性的可达速率的影响不大。此外，当接收天线数趋于无穷大时，给出了可达速率的上界。最后给出了数值结果来验证我们的分析。
In recent studies, a simple non-coherent communications’ scheme based on energy detection is proposed for massive single-input multiple-output systems, where transmit symbols are decoded by averaging the received signal energy across all antennas. In this paper, we investigate the effect of correlated Rayleigh fading on the performance of the aforementioned systems. Specifically, we derive the analytical expressions of the symbol error rate, achievable rate, and outage probability. Furthermore, the asymptotic behaviors of these expressions in regimes of large numbers of receive antennas, high channel correlation, and high signal-to-noise ratio are investigated. The analytical results demonstrate the adverse impact of channel correlation on the error probability, which can be attributed to the fact that channel correlation reduces the degrees of freedom. Our analysis also shows that channel correlation poses little influence on the achievable rate. Besides, an upper bound of the achievable rate is given when the number of receive antennas goes to infinity. Finally, the numerical results are presented to verify our analysis.
