UNITARY REPEATER FOR CANCELLING FEEDBACK INTERFERENCE SIGNALS AND CASCADE RELAY SYSTEM USING SAME

摘要

The present invention relates to a unitary repeater for cancelling feedback interference signals and to a cascade relay system using the same. More particularly, the present invention relates to a cascade relay system using a unitary repeater for cancelling feedback interference signals, wherein the system ensures isolation between antennas using mutually different polarizing characteristics of a donor antenna and a service antenna, and has unitary repeaters for cancelling feedback interference signals, arranged into a cascade structure to provide a radio wave shadow area with optimum communication quality.
