More Information
Summary:A communication device and method may include at least one tuner circuit that monitors at least a first frequency channel and a second frequency channel. A controller of the radio receiver may measure a first received signal strength indicator (RSSI) value over time for the first frequency channel and a second RSSI value over time for the second frequency channel. The first and second RSSI values are based on a signal strength of radio frequency (RF) energy received on the first and second frequency channels, respectively. The controller may detect a leader portion of a message on the first frequency channel responsive to a change in the first RSSI value exceeding a step change threshold. The controller may extract, via a detector circuit, message data from a carrier wave of the RF message.
