Abstract
Elimination of intermodulation interference in a wireless communication system by removing a portion of the spectrum of transmitted signals. According to a received indication of an occurrence of intermodulation interference experienced by a narrowband receiver, mappings are performed between the predetermined narrowband channel frequency on which the narrowband receiver operates and the occupied channel frequencies of at least one broadband transmit signal. Narrowband candidate frequency ranges that linearly combine into frequencies that overlap the predetermined narrowband channel frequency are determined based on the mappings. The narrowband candidate frequency ranges that potentially contribute to the intermodulation interference are then selectively filtered by at least one notch filter until the intermodulation interference is substantially eliminated.
