AI 中文摘要
本文研究了大规模线性天线阵列在近场非视距（NLoS）传播中单边近似的有效性。利用多端口通信理论，评估从接收器返回发射器的电磁相互作用是否可忽略。分析了天线数量增加时固定间距离散阵列和固定孔径连续阵列的情况。结果表明两种情况下该近似平均渐近满足，为下一代无线系统中使用相关瑞利衰落模型提供理论基础。
英文摘要
This paper investigates the validity of the unilateral approximation in near-field non-line-of-sight (NLoS) propagation for large-scale linear antenna arrays. Utilizing multiport communication theory, the study evaluates whether the electromagnetic interaction from the receiver back to the transmitter can be neglected. The analysis examines both discrete arrays with fixed spacing and continuous arrays with fixed aperture as the number of antennas increases. Results show the approximation is asymptotically satisfied on average for both cases. This provides a theoretical foundation for using correlated Rayleigh fading models in physically consistent next-generation wireless systems.
