This letter provides an analysis of the interaction between cooperative diversity and multiuser diversity in downlink channels. Through an approximation of the signal-to-noise ratio (SNR) distribution of each cooperative link using gamma distribution, we can derive an analytic expression for the average throughput of a single-cell wireless system with multiple cooperative diversity links combined with a fair-access scheduler. The proposed analytic approach is verified through comparisons with simulated results and shows that cooperative diversity has a detrimental impact on multiuser diversity.
