Abstract: A system and method for selectively rejecting frequency bands in wireless communication systems are disclosed. For example, the system provides a software-selective band rejection technique using multiple cascaded band rejection filters that can remove undesired sub-bands within the RF pass band of the wireless communication system, subsystem or network involved.

Consequently, the software-oriented band rejection approach enables a designer, operator or user to rapidly configure or reconfigure its designated bands or sub-bands (e.g., on an application-by-application basis) without having to procure and install new bandpass filter hardware or other filter hardware.
