Abstract:

Multi-Carrier Proportional Fair Scheduling (MC-PFS) and Max C/I (MCI) improved algorithms implemented by Genetic Algorithms (GA) are proposed for OFDMA systems. According to the criterion of proportional fairness, MC-PFS searches optimal subcarrier allocation scheme on basis of GA. Simulation results show that near upper bound performance is achieved through GA based MC-PFS. By introducing MCI initial allocation, improved algorithm increases system throughput compare to the upper bound (PF).
