摘要：
To study adaptive sub-carrier allocation in an orthogonal frequency division multiple access (OFDMA) system, the authors applied a particle swarm optimization (PSO) algorithm in the OFDMA system to allocate the adaptive sub-carrier. PSOs characteristically have fewer parameters, rapid speed of convergence and more effective global search capability. These features suggested it would be a better solution for allocation of the sub-carrier in an OFDMA system. Experimental and simulation results proved that performance improved when using the PSO algorithm to allocate the adaptive sub-carrier. It was found to minimize overall transmission power and run more rapidly.
