摘要

本文基于室内衰落环境下5.2 GHz频段的实测数据，研究了圆形阵列MIMO系统的信道自相关和多普勒频谱问题。结果表明，这些衰落特性不仅与RX运动方向有关，而且与阵列方向有关。在NLOS环境下，观测到的多普勒谱与理论形状的Jakes谱有很大的不同。

Channel Auto-Correlation and Doppler Spectrum of MIMO Systems Using Circular Array

In the paper, channel auto-correlation and Doppler spectrum of MIMO systems using the circular array are considered based on measured data conducted at the 5.2 GHz frequency band in an indoor fading environment. The results show that these fading properties are much dependent not only on the direction of the RX motion, but also on the array orientation. In the NLOS environment, observed Doppler spectrum is quite different from the theoretical –shaped Jakes’ one.
