Controlling filter bandwidth based on blocking signals
In one embodiment, a method includes determining in a controller of a radio receiver whether at least one blocker signal is present in a blocking spectrum surrounding a desired radio channel. If no blocker signal is present, a channel filter of a signal processing path of the radio receiver may be controlled to operate at a first bandwidth. If a first blocker signal is present, the channel filter may be controlled to operate at a second bandwidth less than the first bandwidth. If the first blocker signal and a second blocker signal are present on opposing sides of the desired radio channel, the channel filter may be controlled to operate at a third bandwidth less than the second bandwidth, when a beating signal based on the first and second blocker signals is greater than a threshold level.
