A dynamic resource scheduling algorithm for OFDM system

This article presents a practical scheduler algorithm-multiple carrier proportional fairness (MCPF), to dynamically allocate resource for the orthogonal frequency division multiplex (OFDM) system in both frequency and time domain. We analyze its performance on the Doppler fading multipath channel with cocentric system studio and find that the throughput of MCPF is more than 60% greater compared with the fixed scheduling algorithm when there are more than 2 users. This algorithm satisfies proportional fair rule and its throughput performance increases with the number of system user, reaching 100% in 8 users system.
