Abstract

Frequency hopping is a simple and commonly used means for spreading the spectrum of a signal for transmission in a spread spectrum communication system. One central problem in demodulating or efficiently jamming a frequency hopping transmission is accurate estimation of the hopping function. This paper presents some preliminary work in which multiresolution time-frequency techniques are used to estimate the hopping function of an unknown (intercepted) slow frequency hopping signal in an uncluttered environment. Wavelet and short-time Fourier analysis are both used to measure the temporally evolving frequency characteristics of the hopping signal.
