USE OF SYNCHRONISATION AND TIME DISTRIBUTION IN COMBINED SATELLITE-LAND LINE NETWORK WITH MULTIPLEXING WITH ORTHOGONAL FREQUENCY DIVISION Russian patent published in 2011 - IPC H04J11/00 

FIELD: radio engineering.

SUBSTANCE: in the system that includes several transducers, at least, one transducer is located at satellite. Several transducers perform communication with receiver by means of radio communication. Each of some transducers transmits copy of data signal to receiver at some orthogonal subcarrier frequencies. Some transducers are synchronised in such a way that receiver could get data signal copies, basically, simultaneously.

EFFECT: increase of data signal reception validity ensured by the use of recovery facilities of original transmitted data signal.
