Multiuser Diversity in Correlated Rayleigh-fading Channels
Artikel i vetenskaplig tidskrift, 2012

This article studies the effect of scheduling and multiuser diversity on the performance of correlated Rayleigh-fading channels. More specifically, the power-limited channel average rate is obtained for quasi-static correlated fading channels. The results are obtained in the cases where there is perfect or imperfect channel state information available at the transmitter. Simulation results show that the average rate reduction due to channels dependencies is ignorable in low correlation conditions. However, the effect of scheduling and multiuser diversity on the average rate reduces substantially as the fading channels dependency increases. Also, for different channels correlation conditions, considerable performance improvement is achieved via very limited number of feedback bits.
