Abstract:
1. A spectral environment estimation system for use with frequency hopped communications systems, comprising: a spectral sensor configured to receive input signals from a signal aperture and to perform spectral estimations on the input signals to generate a frequency domain spectral estimate as an output; frequency hopping translation circuitry configured to receive the frequency domain spectral estimate from the spectral sensor as an input and to produce a de-hopped channel domain spectral estimate based on the frequency domain spectral estimate; de-hopped spectral characterization circuitry configured to receive the de-hopped channel domain spectral estimate as an input and to produce a de-hopped channel domain spectral environment estimate based on the de-hopped spectral estimate, wherein the de-hopped channel domain spectral environment estimate is a parametric representation of signals in a frequency hopped channel space; and spectral environment integration circuitry configured to generate an integrated spectral environment estimate, based on the de-hopped channel domain spectral environment estimate, for use by networked communications systems or devices in controlling frequency hopped communications.
