ABSTRACT:
Disclosed are a method and system for generating switching a timing signal for separating a transmitting and receiving signal in an optical repeater of a mobile telecommunication network by using a Time Division Duplex (hereinafter, referred to as “TDD”) scheme and an Orthogonal Frequency Division Multiplexing (hereinafter, referred to as “OFDM”) modulation scheme, which transmits a part of a RF signal extracted from a coupler included in a remote of an optical repeater to a switching timing signal generating circuit, locates a frame start position of a RF signal by correlating a reference signal generated in a switching timing signal generating circuit with a RF signal extracted from a coupler, and is capable of transmitting a RF signal by distinguishing between a downlink signal and a uplink signal by using a switching timing signal in a switch when calculating a starting point of a downlink signal and a uplink signal included in an RF signal on the basis of a frame starting location, generating a switching timing signal by using it, and transmitting to a remote's switch.
