ELECTRO-MAGNETIC COMPATIBILITY DESIGN FOR RAPID TRANSIT SYSTEMS
Design criteria and techniques used to minimize the interference levels between the communication and signal channels for control of rapid transit vehicles and other working systems (such as propulsion, power system, auxiliaries, etc.) or the environment, are analyzed in this paper. The particular system under consideration utilizes a higher frequency band to allow a wide separation from signal to noise, but below 10 KHz and at low power level so that it does not require special license to operate. In addition, the use of FSK and the well known features of signal capture as developed in fm systems, are used to further increase the EMC of the overall system. The techniques presented in this paper have been successfully implemented in various transit systems which are presently in operation.
