Xin Zhang · Journal of Circuits and Systems · 2013
An innovatory cyclic spectrum estimation algorithm is proposed based on data division and overlap reservation in limited data length.The procedure is given and the performance of the algorithm is analyzed from the point of estimation variance,the ability of restraining noise,resolution and reliability,and the expression is deduced.It is deduced that the innovatory algorithm can reduce the cyclic spectrum estimation variance and the influence of noise on signal’s cyclic spectrum.The simulation results have proved that the validity of the method.
