A Neural Network Multiuser Detector

本文提出采用Hopfield神经网络实现CDMA多用户通信系统中多用户信号的检测利用基于检测序列最大后验概率最佳多用户检测器的似然函数与Hopfield神经网络的能量函数的对应关系，构造一种离散Hopfield神经网络多用户检测器研究结果表明，这种多用户检测器具有优良的性能，其计算复杂度低于最佳多用户检测器。

A new Hopfield Neural Network multiuser detector is proposed. According to the corresponding relation between the power function of Hopfield neural network and the likelihood function of maximum posterior detective probablilityfor optimum multiuser detector, a discrete Hopfield neural network multiuser, detector is constructed. It is shown that the detector complexity is lower than that of optimal detector, and precedes conventional detector in elimlnating multi-user interference and near-far reslstance.
