METHOD OF AND DEVICE FOR COMBINED RADIO COMMUNICATION AND RADIO NAVIGATION FOR USE IN RAILWAY TRANSPORT Russian patent published in 2006 - IPC B61L25/02 

FIELD: railway signaling and communication.

SUBSTANCE: proposed group of inventions is designed for determining parameters of running train directly at dispatcher station. Said dispatcher station contains PR sequence generator, high-frequency generator, phase keyer, two oscillators, two mixers, first intermediate frequency amplifier, two power amplifiers, transmit and receive antennas, second intermediate frequency amplifier, multiplier, band-pass filter, phase detector, two buffer storage units, correlation processing unit, registration and analyzing unit. Locomotive on-board equipment includes receive and transmit antennas, receiver, change-over switch and transmitter. Parameters of running train are determined using complex signals with phase-shift keying for which correlation processing, transmission and reception at two frequencies are provided.

EFFECT: improved noise resistance and provision of accurate determination of parameters of running train.
