Abstract
A method in a radio communication device having a receiver receiving a wideband signal in the presence of narrowband blockers method in direct conversion and intermediate frequency RF receivers including determining power for signal distortion products (), determining power for a desired signal and the distortion products (), filtering the signal distortion products with a filter having a bandwidth of rejection, and dynamically adjusting a rejection property () as a function of the power for both the desired signal and the signal distortion products. In some embodiments, a determination is made whether a ratio of powers exceeds a threshold () as a condition for adjusting the rejection property.
