Abstract: Under the conditions of minimum total power,required minimum rate of users and allocated minimum power for users,the PSO_GA hybrid algorithm based on particle swarm optimization(PSO) algorithm and genetic algorithm(GA) was proposed for the power line communication(PLC) multiuser orthogonal frequency division multiplexing(OFDM) system dynamic resource allocation.The hybrid algorithm effectively introduces the improved crossover operator and mutation operator from GA to PSO algorithm,so can improve the system’s convergence speed.The hybrid algorithm was tested in the typical power line channels.Simulation results show that the proposed resource allocation scheme based on PSO_GA algorithm achieves faster convergence speed and better performance than the other schemes respectively based on the tradition algorithm.
