IMPROVEMENTS TO SYNCHRONISATION METHODS FOR SINGLE-FREQUENCY SIMULCAST MOBILE RADIO COMMUNICATION NETWORKS Russian patent published in 2012 - IPC H04L7/00 H04W48/10 

FIELD: information technology.

SUBSTANCE: described is a device and a method for synchronising communication signals between a repeater station (S) of a single-frequency simulcast radio communication network (N) and user terminals (T) with respect to a universal reference signal sent by a central station (M) of the network (N) communicating with the repeater station (S). A frequency offset is determined between a universal frequency reference signal received from the central station (M) and a local frequency reference signal of the repeater station (S), and in the repeater station (S) there are provided a first feedback control loop for supplying a signal for controlling a local oscillator of the repeater station (S) based on said determined frequency offset, and a second direct control loop for supplying a signal for compensating residual synchronisation difference of the local oscillator to which the transmitter device of the station (S) is tuned.

EFFECT: high synchronisation accuracy.
