Abstract
A receiver 100 used for recovering modulation signals modulated on a carrier signal is disclosed. The receiver 100 includes a detector 204 and a decoder 206 for detecting the presence of a non-valid coded squelch signal and decoding such signal in the recovered modulation signal. The receiver 100 further includes a synchronizer 208 for synchronizing the detected non-valid coded signal. Receiver 100 is placed in a battery saver mode when a non-valid coded squelch signal is detected. The battery saver mode includes monitoring the recovered modulation signal for a change in the non-valid coded squelch signal. The battery saver mode is departed once a change in the non-valid coded squelch signal is detected.
