Genetic Algorithm Approach for Resource Allocation in Multi-User OFDM Systems

摘要

A novel genetic algorithm application is proposed for adaptive power and subcarrier allocation in multi-user OFDM systems. The proposed method is compared with Eshan's [2] power and subcarrier allocation algorithm and Wang's modified genetic algorithm [23]. Our method has fast convergence and can handle large allocations of subcarriers to users without performance degradation. The simulation results show that our approach is a viable alternative to existing methods for optimum resource allocation.
