Abstract
A remote transmitter system for vehicle applications includes a remote transmitter for carrying by a user and a receiver for mounting on a vehicle and receiving an amplitude modulated signal. The transmitter is operative to transmit the amplitude modulated signal at a plurality of different carrier frequencies. The receiver is programmed to select the carrier frequency for reception by detecting noise due to unwanted frequency modulated signals based on a received signal strength indicator, and detecting noise due to unwanted amplitude modulated signals based on a data decoder. The receiver changes the selected carrier frequency when either noise becomes excessive.
