Abstract:
A method for canceling narrow band interference on a communication channel, the method comprising the steps of:sampling the communication channel to produce a sampled signal; spectrally characterizing the sampled signal across a frequency band of interest to produce a spectral characterization of the sampled signal, wherein the spectral characterization does not include a signal of interest; modifying the spectral characterization of the sampled signal to produce a modified spectral characterization; generating filter settings based upon the modified spectral characterization; filtering the communication channel using the filter settings when the signal of interest is present on the communication channel; and wherein in modifying the spectral characterization of the signal to produce the modified spectral characterization, a noise floor of the spectral characterization is raised to meet a budgeted signal-to-noise level.
