Parameter Estimation of Frequency-Hopping Signals Based on an United Algorithm

摘要：

The paper proposes an amelioration algorithm to the frequency-Hopping (FH) signals parameter estimationUnited Algorithm (STFT-WVD) basted on STFT(Short-Time Fourier Transform)and WVD (Wigner-Ville distribution) to solving the problems of failing time-frequency resolution and oversize operation quantity,which occur in FH signals parameter estimation with Smoothed Pseudo WVD (SPWVD). STFT-WVD could achieve FH signals parameters blind estimation successfully,which include Hop-duration,Hop-timing and Hop-frequency. In the course of parameter estimation,STFT-WVD suppresses the cross-term interference in WVD effectively,and keeps the excellent time-frequency resolution as WVD. Finally,the simulation result proves that the holistic performance of STFT-WVD is better than SPWVD,and STFT-WVD can get more precise parameter estimated values while SNR exceeds -ldB.
