Abstract

Adaptive filters are used to separate frequency hop signals to improve the detection and estimation of the frequency hop signals. In preferred embodiments, two or more adaptive filters (which can be connected in series or in parallel) exhibit different convergence characteristics to isolate a frequency hop signal.
