Abstract: 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.

Abstract: A communication system may include communication devices configured to be onboard vehicles in a multi-vehicle system. Each of the communication devices may operate in a lead mode, a repeater mode, or a trail mode. The communication devices operating in the lead mode may transmit a command signal to control movement of the multi-vehicle system. The communication devices operating in the repeater mode may re-transmit the command signal received from the one or more communication devices operating in the lead mode. The communication devices operating in the trail mode may receive the command signal received from the one or more communication devices operating in the lead mode or in the repeater mode. Each of the communication devices may be remotely switched between the lead mode or the trail mode to the repeater mode.

Abstract: A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.
