APPARATUS AND METHOD FOR SYNCHRONIZING FREQUENCY IN DISTRIBUTED REPEATER
First Claim
1. An apparatus for synchronizing frequency in distributed repeaters, comprising:
- a timing recoverer for compensating sampling timing offset of reception signals;
an intermediate frequency (IF) timing offset information reflector for applying the sampling timing offset information extracted in the timing recoverer to digital-to-analog conversion; and
a radio frequency (RF) timing offset information reflector for applying the sampling timing offset information extracted in the timing recoverer to RF up-conversion as a reference signal.

Abstract
Provided is a frequency synchronizing apparatus and method that can synchronize center frequency of radio frequency (RF) transmission signals among distributed repeaters using identical signals as mother signals by reflecting sampling information acquired in a timing recovery process of reception signals transmitted from a main transmitter or other repeaters. The apparatus for synchronizing frequency in distributed repeaters includes: a timing recoverer for compensating sampling timing offset of reception signals; an intermediate frequency (IF) timing offset information reflector for applying the sampling timing offset information extracted in the timing recoverer to digital-to-analog conversion; and a radio frequency (RF) timing offset information reflector for applying the sampling timing offset information extracted in the timing recoverer to RF up-conversion as a reference signal.
