基于改进粒子群优化的联合处理频谱分配算法
Spectrum allocation algorithm using improved particle swarm optimization
摘要
Abstract
In the coordinated multi point transmission/reception single user joint processing (CoMP SU JP) system,the spectrum allocation algorithm was proposed based on improved particle swarm optimization (PSO).Aiming at maximizing the performance of cell edge users (CEUs) and total cell users (TCUs),the limited nonlinear 0-1 programming model was established for spectrum allocation in CoMP SU JP by introducing the CEU weighting factor.The spectrum allocation algorithm based on improved PSO was designed for this model.The simulation results show that the proposed algorithm balances the performance of CEUs and TCUs by adjusting the weighting factor and has a flexible implementation.Compared with other existing algorithms,the CEU throughput and TCU throughput of the algorithm are improved significantly when the weighting factor is set properly.关键词
