| 摘 要： | 多用户检测技术是第三代移动通信系统CDMA中的一项关键技术,在多用户检测中求解最佳矢量问题可以转化为在免疫算法中求解具有最高适应度函数的问题。文章提出了一种基于免疫算法的CDMA多用户检测,并与最佳多用户检测和传统检测器进行比较,实验结果表明该方法可获得接近最佳检测的性能。

| Abstract: | The techniques of multi-user detection are crucial for the implementation of code division multiple access(CDMA) in the 3rd mobile communication system. It is shown that the problem of minimizing the objective function of the optimal multi-user detector can be translated into finding the individual, which has the high fitness in the immune algorithm. A multi-user detector based on the immune algorithm is proposed and compared with the optimal multi-user detector and the conventional detector,and the results show that the performance of the proposed method is close to that of optimal multi-user detector. |
