METHOD OF DIGITAL TRAIN RADIO COMMUNICATION ON RAILWAY TRANSPORT Russian patent published in 2012 - IPC B61L27/00 

FIELD: transport.

SUBSTANCE: invention relates to electric communication technique, primarily to digital conventional radio communication and can be used for organisation of digital train radio communication on railway transport. The method includes voice signals transmission from train dispatcher to train locomotive driver over line channel between control station and fixed radio station and further over radio channel between fixed and locomotive radio stations. In line channel, voice signals of train dispatcher are transmitted in digital form, and in radio channel, time-frequency channel demultiplexing is performed. Between control station and fixed radio stations, digital data or voice signals of closed railway stations train locomotives drivers are transmitted over additional digital line channel. On each frequency, packet transmission is performed using two time-slots with protective interval between them. One time-slot is used to transmit data of main line channel, while the other time-slot is used to transmit data of additional line channel. Data transmission is executed in packet form.

EFFECT: higher quality and reliability of train radio communication.
