摘要
多址干扰的存在是影响CDMA系统性能和限定系统容量的重要因素。针对多址干扰信号的特点 ,研究了一种改进的硬判决并行干扰多用户检测器。分析和仿真结果表明 ,该多用户检测器具有更好的性能和抗远近效应的能力 。
Multi access interference (MAI) is the major factor degrading the CDMA system performance and capacity. According to the characteristics of MAI in CDMA systems, a multi user detector is designed by a new hard decision parallel decision algorithm for MAI cancellation. Analysis and simulation results show that this detector performs better and has larger capacity to restrain near far impact than the conventional ones, and hence has good potential for practical application.
