A new hop rate estimation method for high-speed frequency-hopping signals

Abstract

The key to jam frequency-hopping communication is to estimate its parameters efficiently and precisely. An algorithm for estimating the hop rate of high-speed 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 hop rate of FH signals. Simulation results demonstrate that the estimation algorithm is accurate and efficient.
