Multiuser Scheduling Over MIMO Nakagami-m Fading Channels: Capacity and BER Performance

Free registration required

Executive Summary

A performance analysis for the average channel capacity and average Bit Error Rate (BER) of user scheduling schemes for multiuser MIMO systems exploiting the multiuser and antenna diversities over non-identically distributed Nakagami-m fading channels is presented. The authors consider different scheduling schemes including absolute SNR-based scheduling and normalized SNR-based scheduling schemes for both heterogeneous and homogeneous wireless networks. They derive expressions for the Probability Density Function (PDF) and Cumulative Distribution Function (CDF) of the Signal-to-Noise-Ratio (SNR) in non-identical Nakagami-m MIMO channels for each scheduling scheme.
