| 摘 要： | 与准静态独立的瑞利衰落信道模型相比较，在MIMO(Multi-Input Multi-Output)系统中，实际信道更趋向于空时相关莱斯快衰落。考虑到MIMO系统的收发分集优势以及收发两端天线阵列的空时相关性，在简单论述了MIMO系统和信道模型的基础上，该文利用多变量统计学理论，推导出MIMO系统在空时相关莱斯快衰落信道下平均成对差错概率上界的闭合表达式，并探讨了信道特性对系统性能的影响，然后给出相应仿真结果。

| Abstract: | Compared with the quasi-static rayleigh fading model, in MIMO (Multi-Input Multi-Output) systems, the practical channel is better for the spatial correlated fast Rician fading. Considering the transmit and receive diversity advantage in MIMO system and spatiotemporal correlation in transmitter and receiver arrays, based on the simple discussion about the MIMO system and channel model, this paper derive the close-form solution of the upper bound of the average pairwise error probability of the MIMO system under spatiotemporal correlated fast Rician fading by use of multivariate statistics, and the effect of the characteristic of the mobile channel on the system performance is discussed. Finally, the simulation results are shown. |
