Abstract
A system that incorporates teachings of the subject disclosure may include, for example, a method for identifying a spectral region in a radio frequency spectrum for initiating a communication session having a transmission link and a reception link, determining a correlation factor from signals measured in the spectral region, detecting according to the correlation factor a foreign communication signal in the spectral region, generating coefficient data to prevent interference with the foreign communication signal while transmitting in the transmission link, filtering a first signal for transmission in the transmission link according to the coefficient data to generate a filtered signal, and causing a transmission of the filtered signal which prevents interference with the foreign communication signal while transmitting in the transmission link. Other embodiments are disclosed.
