摘要
定量分析了具有多用户检测功能的CDMA移动通信系统的容量和覆盖,讨论了采用遗传算法实现多用户检测的方法,仿真结果表明无论是抗多址干扰还是抑制远近效应,基于遗传算法的多用户检测技术都明显优于传统检测器。
In this paper, the coverage and capacity in CDMA Systems with multi-user detection technique are analyzed. A genetic algorithm based multi-user detection technique is presented. With the computer simulation, it is shown that the new multi-user detection technique has better performance than the conventional multi-user detection technique in terms of both the resistance on the multiple access interference and the near-far effects.
