MIMO Detection Performance for Realistic Rician Fading of Estimated Statistics
The multiple-input multiple-output (MIMO) technique can greatly improve coverage and throughput in wireless networks. However, varying channel parameters create unfavorable conditions that make the transmission less reliable. Unfortunately, many previous MIMO evaluations suffer from limited practical relevance due overlysimplified assumption about the channel fading model and parameters. Therefore, it is important to match reality and thus acquire a more accurate understanding of MIMOs expected performance and challenges. In this paper, we investigate MIMO performance when the transmit and receive antennas experience correlation and when the channel gain matrix and its statistics (i.e., statistical channel state information—SCSI) are estimated. Furthermore, we investigate the effect of realistic random and correlated azimuth spread (AS) and K-factor. Numerical results for typical urban scenario demonstrate the performance difference between the unrealistic and realistic assumptions about channel knowledge and fading model.
