DESIGN OF TRANSPONDER SIGNALS AND RECEIVERS FOR AUTOMATIC VEHICLE LOCATION AND IDENTIFICATION SYSTEMS

Systems which locate and identify moving vehicles without the active cooperation of either the vehicle operator or its passengers are being considered for various applications, including identification and subsequent billing for vehicles passing toll booths, and location and identification of railroad locomotives. This paper considers the design of identification signals transmitted from (to) a moving vehicle to (from) roadside receivers (transmitters) at various known locations. It is shown that use of simple binary codes, including constant ratio or single parity check codes, in conjunction with signal averaging, often yields better performance at less cost than systems which employ complex coding/decoding schemes.
