摘要

Focusing on the resource allocation problem in multi-user orthogonal frequency division multiple access (OFDMA) systems, a multi-carrier proportional fair scheduling algorithm, G-PFS, is proposed. G-PFS searches optimal subcarrier allocation through genetic algorithms. By adding maximum carrier-to-interference ratio individual to the initial population and keeping its gene stable, an improved algorithm MG-PFS is proposed. Simulation results show that G-PFS approximate theoretical fair upper bound. MG-PFS provides higher system throughput than G-PFS.
