Abstract
Military communication systems do not necessarily operate within FCC frequency bands. Hence, they
may be subject to interference from other waveforms using the same frequency band. In this paper we first investigate a technique to estimate the spectrum of competing signals utilizing the same bandwidth as a desired frequency-hopped waveform. Next, we show that the desired frequency-hopped waveform can be recovered from the composite received signal by dividing the composite signal spectrum by an estimate of the interference spectrum. Since the interference estimate is imperfect, spectral division is significantly better than spectral subtraction of the interference spectrum from the composite spectrum for the detection of frequency-hopped waveforms.
