Patent number: 8279987Abstract: A filter settings generation operation includes sampling a communication channel to produce a sampled signal. The sampled signal is spectrally characterized across a frequency band of interest to produce a spectral characterization of the sampled signal. This spectral characterization may not include a signal of interest. The spectral characterization is then modified to produce a modified spectral characterization. Filter settings are then generated based upon the modified spectral characterization. Finally, the communication channel is filtered using the filter settings when the signal of interest is present on the communication channel. In modifying the spectral characterization, pluralities of spectral characteristics of the spectral characterization are independently modified to produce the modified spectral characterization. Modifications to the spectral characterization may be performed in the frequency domain and/or the time domain.Type: GrantFiled: February 14, 2011Date of Patent: October 2, 2012Assignee: Broadcom CorporationInventors: Thomas J. Kolze, Bruce J. Currivan, Jonathan S. Min, Eric J. Ojard, James Chi Thi, Daniel H. Howard
