摘要
Abstract
Aiming at synchronization of burst communications,this paper firstly introduces a method of matched filtering based on quadrature down-conversion and digital sampling,then analyzes the influence of frequency offset on matched filtering.It proposes a synchronization method based on matched filtering with frequency offset pre-correction,then analyzes the performance of synchronization by matched filtering with and without frequency offset pre-correction and after demodulation without frequency offset.In the end,the modeling simulation and analysis of the synchronization performance of the three cases under the condition of low signal noise ratio.关键词
