摘要

假设一个频率平坦的慢瑞利衰落信道具有多个发射和接收天线，我们研究了当接收端假设信道参数估计是完美的或使用适当的最大似然决策度量时，信道参数的不完全估计对系统性能的影响。提出了一种用于网格空时码的最大似然决策度量递归计算算法。

Space-time decoding with imperfect channel estimation

Under the assumption of a frequency-flat slow Rayleigh fading channel with multiple transmit and receive antennas, we examine the effects on system performance of imperfect estimation of the channel parameters when the receiver either assumes that the estimate is perfect or uses a proper maximum-likelihood decision metric. An algorithm for the recursive calculation of the maximum-likelihood decision metric is developed for application to trellis space-time codes.
