码分多址中的几种用户检测技术的分析与比较

Analysis and Comparison of Several User Detection Approaches in Code Division Multiple Access Systems

着重分析了在码分多址 (CDMA)数字蜂窝移动通信系统中的三种用户检测技术 .通过数学分析的方法 ,对这三种用户检测技术在抗多址干扰和抗“远 -近”效应方面的特性 ,以及在同等条件下的误比特率进行了比较和分析 ,并给出了仿真运行的结果和应用场合分析 .

This paper mainly analyzes three user detection approaches in digital cellular mobile communication systems based on CDMA.Firstly,the performances of three approaches on anti multi address interferences and anti“far-near” effects,and their bit error ratio(BER) under equivalent conditions are mathematically compared and analyzed.The simulation results of three approaches are then presented and their applications are analyzed.
