针对码分多址接入(CDMA)系统中最优多用户检测的指数计算复杂度问题,结合CDMA通信的实际特点,利用进化规划免去了交叉操作因而计算复杂度小的特点,提出了一种基于进化规划的多用户检测问题的优化处理方法。实验结果表明本方法可获得接近最佳检测的性能,但计算复杂度降低。 |

Abstract: |
With respect to the exponential computation complexity of the optimal multi-user detection(MUD) in CDMA systems,a sub-optimal multi-user detector based on evolution strategy for exonerating crossover operation and lowing computation complexity is proposed.The simulation results show that the performance approaches the optimal multi-user detector while the complexity is much lower. |
