A parameter estimation algorithm for high-speed frequency-hopping signals based on RSPWVD

Abstract

The key to jam frequency-hopping communication is to estimate its parameters efficiently and precisely. An algorithm for estimating the parameters of frequency hopping (FH) signals based on reassigned smoothed pseudo WVD (RSPWVD) is proposed. With the good time- frequency concentration and restraining cross-term ability of RSPWVD, this algorithm can efficiently estimate the parameters of FH signals such as hop duration, hop timing and hop frequencies. Simulation results demonstrate that the estimation algorithm is accurate and efficient.
