Abstract
A system and method provide adaptive filtering of radio frequency (RF) signals. Multiple signals are received in a predetermined RF spectrum, the signals including a desired signal and multiple potentially interfering signals. A first signal of the potentially interfering signals is down-converted to a baseband signal, and a power of the baseband signal is determined. When the power exceeds a predetermined threshold power, a first notch filter, corresponding to a frequency of the first signal, is activated.
