摘要翻译:
本文从启发式粒子群优化(PSO)的角度研究了直序码分多址(DS-CDMA)上行链路多用户检测问题(MuD)。针对高阶调制和分集开发等未来技术的不同系统改进,给出了一套完整的粒子群优化算法用于MuD问题的参数优化过程,这是本文的主要贡献。此外,通过蒙特卡罗模拟,对PSO-MuD的性能进行了简要分析。仿真结果表明,经过收敛后的PSO-MuD检测器的性能明显优于传统检测器,接近于单用户界(SuB)。最初考虑的是瑞利平坦信道,但结果进一步推广到分集(时间和空间)信道。

英文摘要:
In this paper, the uplink direct sequence code division multiple access (DS-CDMA) multiuser detection problem (MuD) is studied into heuristic perspective, named particle swarm optimization (PSO). Regarding different system improvements for future technologies, such as high-order modulation and diversity exploitation, a complete parameter optimization procedure for the PSO applied to MuD problem is provided, which represents the major contribution of this paper. Furthermore, the performance of the PSO-MuD is briefly analyzed via Monte-Carlo simulations. Simulation results show that, after convergence, the performance reached by the PSO-MuD is much better than the conventional detector, and somewhat close to the single user bound (SuB). Rayleigh flat channel is initially considered, but the results are further extend to diversity (time and spatial) channels.
