一种基于FPGA和Matlab的时延测量方法
A Method of Measuring Time Delay Based on FPGA and Matlab
摘要
Abstract
A method of measuring time delay based on FPGA and Matlab is presented to meet the demand of precise measurement of time delay in the field of deep space communication.The principle is elaborated,and the time delay of one piece of optical fiber of 1 km in length is measured.The results show that the time delay can be measured with an accuracy of 1ps when a tone is transmitted, and the standard deviation of time delay values of optical fiber path is 2.0 ps when frequencies of transmitted tones range from 800 MHz to 900 MHz.关键词
