The Research on the Space Correlation in MIMO Systems
不同传输环境下MIMO信道的空间相关性的研究

The space correlation is analyzed in different propagation conditions including the MIMO macro-cell and micro-cell applications. The characteristics curves describing the space correlation versus the distance of antennas are obtained according to the numerical analysis. The effect of the spread of the angle of arrival on the space correlation is also investigated. Besides, the impact of the space correlation on the system performances is discussed here. The thresholds of the space correlation coefficients influencing BER performance under different propagations are also found by BER analysis.
