Yi Cao · Radio and communications technology · 2007
In this paper,a fast algoritim to analyze time-frequency distribution of non-stationary signals is given.It is called algorithm of shift window’s average frequency.This algorithm features both simple complicating and high efficiency.Effectiveness and reliability of the algorithm are proved by MATLAB simulation.An application to identify digital modulation signals from noise is presented,the identification performance can be improved by this algorithm.
