摘要
本文研究了一种应用于移动通信系统中收发端皆为多天线系统的MIMO信道建模的方法,将功率延迟函数,空域相关以及时域衰落融入到信道模型中,充分考虑了时延扩散、多普勒效应、波达方向、角度扩展、到达角功率谱分布等多种信道参数。并且根据3GPP.25.996标准中的相关参数对此MIMO信道模型进行了仿真。结果表明,该模型得出的仿真值与理论值比较贴近。
This document studies a method of MIMO channel modeling and simulation for mobile communication system. Both spatial correlation and fading in time domain are integrated into this model, and many channel parameters such as time dispersion, Doppler effect, direction of arrival, azimuth spread, and power azimuth spectrum are fully considered in this model. We simulate this MIMO channel according to the parameters of 3GPP.25.996.The result show that the new method matches the analytical result very well.
