RF REPEATER FOR COMPENSATING DELAY TIME BETWEEN RAS AND REPEATER AND METHOD FOR GENERATING SWITCHING TIMING SIGNAL COMPENSATING DELAY TIME BETWEEN RAS AND RF REPEATER IN OFDM-TDD TYPE WIRELESS BROADBAND SYSTEM

摘要

The present invention relates to a RF repeater, and the signal propagation delay time compensation method for generating a switching timing signal to RF repeaters to compensate for signal transmission delay time from the RF repeater in the WiBro system. ; Signal propagation delay time compensation switching timing signal generating method of the present invention is a method for generating a switching timing signal for the switch control for the signal separated by the RF repeater of a WiBro system using the OFDM-TDD system, RF from the base station to the RF repeater When a signal is transmitted, and a first step of determining a frame start position of the RF signal; Based on the frame start position and a second step of calculating a starting point of the uplink signal and the downlink signal included in the RF signal; A third step ahead of the start point of the uplink signal by twice the calculated (2D) of the signal propagation delay time (D) compensate for signal propagation delay time; A fourth step of the transfer switch of the RF repeater by generating a switching timing signal by using the starting point of the downlink signal calculated in the second phase information and starting point information of the first delay-compensated uplink signal at step 3; There is a technical feature yirueojim including; and a fifth step of transmitting the switching timing signal to separate the upstream signal and the downstream signal by controlling the switch by a.
