Abstract

The information for operating the train should be transmitted to train, with extreme security. In our system, The information, such that the allowable velocity of the train, train existence in current area, and other data necessary for operating train, is transmitted in the form of FM signal. Received by the receiver located on train, the signal is filtered, demodulated, and analyzed for extracting the original information. The analysis of the demodulated signal is done through FFT algorithm using sliding slot. The simulation results shows the validity of the algorithm.
