摘要
Abstract
Based on the principle of Orthogonal Time Frequency and Space(OTFS)modulation,this paper designs an OTFS waveform scheme based on Zero Suffix(ZP)protection.Methods of synchronization,channel estimation,and the detection algorithm based on delay-time domain Maximum Ratio Combining(MRC)are presented,and the MRC detection algorithm is simplified.Hard-ware implementation schemes of channel interpolation and the MRC detector are given.And the Field Programmable Gate Array(FP-GA)hardware implementation of the proposed OTFS system waveform is carried out to verify the feasibility of the key algorithms of the designed OTFS system.Test results show that the designed OTFS system has good performance in resisting doubly selective fading.关键词
