Deep Learning-based Receiver Design for Affine Frequency Division Multiplexing
摘要
Abstract
In this research,a deep learning-based receiver is designed for Affine Frequency Division Multiplexing(AFDM)over doubly selective fading channels.A Deep Neural Network(DNN)is constructed,trained offline using training data,and then deployed online at the receiver to output transmitted bits.Simulation results demonstrate that the proposed deep learning-based receiver achieves comparable Bit Error Rate(BER)performance with respect to the conventional channel estimation scheme when a guard interval exists between the pilot and data.Notably,as the guard interval between the pilot and data decreases,the BER performance of the deep learning-based receiver surpasses that of the traditional channel estimation scheme.Moreover,the proposed receiver exhibits greater robustness than existing schemes in the presence of pilot-data interference.关键词
