Apparatus and method for synchronizing optic repeater in communication system using time division OFDM scheme

摘要

Disclosed is a method for synchronizing of a first signal and a second signal in a communication system including a mobile station, an base station and an optic repeater, the base station and the optic repeater being connected via an optical cable. The first signal is transmitted between the base station and the mobile station, and the second signal is transmitted between the base station and the optic repeater The method includes transmitting the first signal after delaying the first signal by a predetermined fixed delay time when it is necessary to transmit the first signal; and synchronizing the second signal with the first signal by delaying the second signal by an adaptive delay time determined according to a predetermined scheme.
