摘　　要：用连续Ｈｏｐｆｉｅｌｄ神经网络实现ＣＤＭＡ通信系统中多用户信号检测的设想，并针对同步ＣＤＭＡ系统构造了基于连续Ｈｏｐｆｉｅｌｄ神经网络的用户信号检测器。计算机仿真结果表明：这种检测器的性能远远优于传统检测器的性能，它的性能可与最佳多用户信号检测相比拟。According to hypothesis about the implementation of multi-user signal detector with continuous Hopfield neural network a kind of Hopfield -based multi-user signal detector for synchronous DS / CDMA (Direct Sequence Code Division Multiple Access)system has been constructed . A computer Simulation shows that this detector perform ance is quite superior than that of the conventional one . Its performance can be comparable with that of the optimum detector .
