摘要:

提出了适用于OFDMA系统,采用遗传算法的多载波比例公平调度(MC-PFS)及最大信干比(MCI)改进算法。根据比例公平准则,MC-PFS通过遗传算法搜索最优子载波分配方案。仿真结果表明采用遗传算法的MC-PFS可获得近似理论上界的性能。通过引入MCI初始分配结果,改进算法可提供比理论上界(比例公平)更高的系统吞吐量。

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).
