摘要

我们提出了一种新的计算效率高的时变多径(快速衰落)矢量信道模拟器，可用于评估天线阵列无线接收机的性能。仿真器的开发是基于对矢量信道时空相关特性的仿真。该信道被建模为具有时变系数的多通道FIR系统，时变系数是通过对一些独立随机序列进行空时相关整形变换得到的。详细介绍了新模拟器的各个部分，并给出了信道仿真的实现和评论。

A new multi-path vector channel simulator for the performance evaluation of antenna array systems

We present a new, computationally efficient simulator for time-varying multi-path (fast fading) vector channel that can be used to evaluate the performance of antenna array wireless receivers. The development of the simulator is based on the emulation of the spatio-temporal correlation properties of the vector channel. The channel is modeled as a multi-channel FIR system with time-varying coefficients which are obtained via the application of a space-time correlation shaping transformation on some independent random sequences. The various parts of the new simulator are detailed and channel simulation realizations are presented and commented.
