摘要
This work studies the average probability of error for randomized space-time codes (RSTCs) when channel state information (CSI) is not perfect. We show that the diversity order of RSTC using the maximum-likelihood channel estimation and the mismatched receiver is the same as that of RSTC with perfect CSI. However, the coding gain is affected by a factor which decreases to 1 as the number of pilot symbols utilized in the channel estimation increases. In addition, we show that as the number of relays increases the performance improves.
