本文提出了一种用于卫星通用移动电信系统 (S-UMTS) 信道均衡的径向基函数 (RBF) 神经网络 (NN) 方法。 S-UMTS 通信中存在两个主要问题：(i) 由板载非线性功率放大器引起的非线性失真，以及 (ii) 多径传播。本文表明 RBF 网络特别适合克服这些问题。本文提出的几个仿真结果表明，对于不同的移动信道配置（移动速度、噪声水平、路径数量等），RBF 网络的性能优于经典均衡技术。
The paper proposes a radial basis function (RBF) neural network (NN) approach to satellite universal mobile telecommunication system (S-UMTS) channel equalization. Two main problems arise in S-UMTS communications: (i) non-linear distortions which are caused by the onboard nonlinear power amplifiers, and (ii) multipath propagation. This paper shows that RBF networks are particularly well suited to overcome these problems. The paper presents several simulation results which show that RBF networks outperform classical equalization techniques for different configurations of the mobile channel (mobile speed, noise level, number of paths, etc.).
