Abstract

We analyze the influence of mobility on downlink performance of a wireless communication system. We first summarize some previously obtained information theoretic results, followed by a review of multiuser diversity systems. Then we introduce several first-order Markov chain models for use with multiuser diversity scheduling algorithms, in order to obtain quantitative performance results. Finally we propose an improved scheduling algorithm and compare its performance against that of a known scheduling algorithm.
