AUTOMATIC CAB SIGNALING ADAPTIVE SIGNAL RECEIVER Russian patent published in 2007 - IPC B61L25/06 

FIELD: railway transport; signaling and communication.

SUBSTANCE: invention relates to continuously controlled cab signaling systems. Proposed adaptive receiver contains series-connected coded signal reception unit, analog-to-digital converter implementing Fourier transfer function, first on-line storage, averaged signal spectrum forming unit and second on-line storage, correlative comparator, control pulse shaper, switch element and correlative identificator of automatic cab signaling signal spectrum which is output of adaptive receiver. First and second outputs of second on-line storage are connected, accordingly, to first and second inputs of correlative comparator. Output of clock-pulse generator is connected to control inputs of first on-line storage, averaged signal spectrum forming unit, second on-line storage and correlative comparator.

EFFECT: improved reliability of identification of signals of continuously controlled cab signaling system at external interference and instability of carrier frequency of coded signals.
