Abstract

The differential space-time block code is well-known to provide full spatial diversity and allows simple differential detection. Recent results have shown performance degradation when the channel is time-varying. The letter shows the effect on error performance of spatial correlation between transmit antennas. A generalized receiver which exploits spatial correlation information, is proposed and shown to outperform an existing receiver in terms of frame error rate for slowly varying channels with moderate to high spatial correlation.
