摘要： 研究了径向基函数网络（RBFN）在正交频分复用（OFDM）系统快衰落信道估计中的应用，提出了一种基于分散导频的RBFN信道估计器。较之基于梳状导频的RBFN 估计器，该估计器极大地提高了频带利用率，且具有良好的误码率性能。

Abstract: The application of radial basis function network (RBFN) to channel estimation in OFDM systems is investigated, and a scattered pilot-based RBFN channel estimator is presented. Compared with the comb pilot-based RBFN channel estimator, this estimator greatly increases thebandwidth efficiency and shows good BER performance
