摘要

在DS-CDMA通信系统中,每个用户通过唯一的扩频码来调制二进制数据。在接收机的一侧,需要的用户信号必须从求和信号中分离出来。本文提出了一种基于子空间分离器和功能链路神经网络的分离目标用户、消除同信道干扰和附加高斯噪声的方法。最后给出了结合这两种技术的接收机的计算机仿真结果

Subspace Separator and Functional Link Neural Network Based Receiver for DS-CDMA Signal
In DS-CDMA communication systems, each user is distinguished by a unique spreading code to modulate binary data. At the side of the receiver, the signal for the desired user must be separated from the summed signal. This paper presents a subspace separator and functional link neural network based method to separate the desired user and eliminate the co-channel and interference as well as additional Gaussian noise. At last some computer simulation results of the receiver combining these two techniques are given
