Abstract
A receiver ( ) uses a scanning technique ( ) to minimize scan time. An initial bandwidth setting is selected that covers multiple channel frequencies ( ). A signal detection step ( ) is performed looking for channel activity. As channel activity is detected, the bandwidth of a baseband filter ( ) is narrowed ( ). The radio remains programmed to the same channel while the bandwidth is varied. Once the last signal detection with the narrowest possible bandwidth setting has been determined ( ) the radio is programmed to that channel. Thus, more than one channel frequency is capable of being scanned without reprogramming the radio to a new channel for each scan.
