摘要
研究了MMSE线性多用户检测接收机在单用户DS-UWB系统中的应用,推导了接收机的信号模型以及滤波器权向量的计算公式,分析了其性能.仿真实验表明,在IEEE 802.15.3 a信道中,线性多用户检测接收机比选择Rake接收机(S-Rake)具有更好的能量收集和多径干扰抑制能力.
This paper studied the application of MMSE （ mini metal state examination） linear multiuser detection receiver in the single user DS-UWB system. The signal model of the receiver and the weight vector of the filter were derived. The performance of linear muhiuser detection receiver was analysed. Simulation results show that the linear multiuser detection receiver has better performance than selective Rake receiver（S-Rake） in both energy collecting and muhipath interference suppression in dense multipath channel.
