METHOD OF SYNCHRONISING CLOCK SIGNALS OF EXPORT MODULE AND EXCITER Russian patent published in 2010 - IPC H04J3/06 H04L7/00 

FIELD: information technology.

SUBSTANCE: method of synchronising a clock signal of an exciter with a modem frame clock signal in an IBOC radio broadcasting system involves receiving multiple modem frame pulses which represent the onset of modem frames of audio signals and data signals. The time positions of the modem frame pulses are controlled by the modem frame clock signal. An exciter clock signal is generated. Pulses representing the exciter clock signal are counted so as to form a reading representing the error in the time position of each input modem frame pulse, and the exciter clock signal is controlled in response to this reading.

EFFECT: higher synchronisation accuracy.
