Abstract
A method for reducing adjacent channel interference begins by determining a desired channel of a radio frequency (RF) signal. The method continues by determining a plurality of potential local oscillations for the desired channel. The method continues by determining a proximal power level of an image frequency of each of the plurality of potential local oscillations to produce a plurality of proximal power levels. The method continues by selecting one of the plurality of potential local oscillations for down converting the desired channel based on the plurality of proximal power levels.
