OPTICAL RELAY SYSTEM TO COMPENSATE RADIO WAVE TRANSMISSION DELAY DUE TO MULTIPATH AND METHOD FOR RELAY THEREOF

摘要

The present invention relates to an optical relay system and, more particularly, to an optical relay system for compensating radio wave transmission delay due to a multiple path, capable of smoothly recovering a signal by reducing the delay time difference of a transmission signal due to various paths by including a delay compensation circuit with various delay filters in an optical master unit. The optical relay system according to the present invention includes at least one bidirectional amplifier, at least one optical remote unit, the optical master unit, and a base station.
