| 摘 要： | 针对CDMA系统中的多用户检测问题,提出了一种应用恒模性质的新算法.分析了衰落信道下的等效离散接收信号模型,给出其矩阵表达式,进而推导出了接收端均衡器的权系数与等效扩频码矩阵间的关系.计算机仿真表明该算法理论正确,可以获得较好的收敛特性.

| Abstract: | To suppress multi-access interference in CDMA system,a new Multi-User Detection(MUD) approach in fading channel based on constant modulus algorithm(CMA)is proposed in this paper.The equivalent discrete receiver signal is modeled and denoted in matrix expression form.Also,the relations between taps of receiver equalizer and equivalent spread spectrum code matrix are deduced.Computer simulation results show that is is effective and feasible. |
