APPARATUS FOR COMPENSATING DELAY TIME IN OFDM MOBILE WIRELESS COMMUNICATION SYSTEM

摘要

The present invention is an up / down (Up / Down) provided with a base stations and remote repeaters OFDM (Orthogonal Frequency Division Multiplexing) mobile radio communication system, it relates to a link delay time compensation unit. In at least one or more optical repeater remote one OFDM mobile radio communication system having the base station up / down of the base station-link delay compensation unit delay to light is set to pre-up of the optical line between the optical repeater remote and base station down the combined time and remote own delay (down) - link data delay time of down generate-link delay generating section, the down-up for generating a link delay-link same up (up) and the data delay - operation unit generating link delay times and from the terminal up-link delay generating unit, and the terminal down to-link data transmission when the downlink data received during the up-operates link delay generation unit to the control unit for compensating for an optical repeater delay It characterized in that it comprises.
