ABSTRACT:
A method and system for spectral suppression of a noise in a communication signal. The method includes transmitting a communication signal through a plurality of rejection filters to create a plurality of spectral holes over a spectrum of the communication signal. The communication signal with an acquired noise is received. Noise intensities of the acquired noise at the plurality of spectral holes are measured, and the acquired noise over the spectrum of the communication signal is calculated. The acquired noise is subtracted from the communication signal with the acquired noise.
