Abstract
Under the circumstance of lack the knowledge of hopping frequency location, a time-frequency transform algorithm for identifying the parameters of frequency hopping communication signals in additive white Gaussian noise is proposed in this paper. The signal parameters to be identified include hopping frequencies, hopping rate, and hopping sequence. The proposed method is based on the time-frequency representation of the intercept signal to identify the parameters of the frequency hopping signals. Then, the computational complexity and simulation results of the proposed algorithm are presented to evaluate the performances which are given in terms of the root mean square error.
