为了综合遗传算法和粒子群算法的优点,提出了一种新的遗传粒子群算法。并将这三种进化算法成功地应用于多输入多输出检测问题。仿真结果表明,与基于粒子群优化的检测方法和基于遗传算法的检测方法相比,基于GPSO的检测算法所需的种群规模和迭代次数要少得多。此外,与最优最大似然检测方法相比,基于GPSO的检测算法可以在误码率性能和计算复杂度之间取得更好的平衡。版权所有©2012 John Wiley&Sons,Ltd.
In this paper, with the purpose of integrating the advantages of both the genetic algorithm and the particle swarm optimization, a new genetic particle swarm optimization (GPSO) algorithm is proposed. Furthermore, these three evolutionary algorithms are successfully applied to address the MIMO detection problem. Simulation results reveal that the GPSO‐based detection algorithm takes much less population size and iteration number when compared with the particle swarm optimization‐based detection method and the genetic algorithm‐based detection method. Besides, when compared with the optimal maximum likelihood detection method, the GPSO‐based detection algorithm can strike a much better balance between the BER performance and the computational complexity.
