水声通信中多普勒系数估计方法研究
Study on Doppler Coeffcients Estimate in Underwater Acoustic Communication
摘要
Abstract
According to the Doppler Effect in the underwater acoustic communication,this paper puts forward Doppler coefficient estimation based on Notch filter.This method makes use of Notch filter to estimate the channel narrowband CW pulse signal frequency,and then gets the Doppler coefficient,and makes a comparative analysis of the Doppler coefficient based on the broadband signal.Finally,the paper makes a comparative study through the computer simulation based on the CW pulse frequency estimation and Doppler coefficient estimation based on the broadband signal,and gives two methods of their advantages and disadvantages and occasions of application.关键词
