| 摘 要： | 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,提出了一种基于改进的进化规划多用户检测方法,该方法是通过增加种群的多样性来改善进化规划易于出现早熟收敛的缺点。实验表明,该多用户检测方法在抗多址干扰的能力和抗远近效应的能力都优于进化规划的多用户检测方法。

| Abstract: | In view of the exponential computation complexity of the optimal multi-user detection in Code Division Multiple Access(CDMA) systems and the practical characteristic of CDMA communication,a sub-optimal multi-user detector based on the modified evolution strategy is proposed.The premature convergence of the evolution strategy is avoided by means of increasing the race individual.The simulation results have shown that in the aspects of multiple-access interference cancellation and near-far resistance,the detector using the presented algorithm is better than that using the evolution strategy. |
