WIDE BAND RADIO RELAY APPARATUS FOR MOBILE COMMUNICATION

摘要

PURPOSE: A wide band radio relay apparatus for a mobile communication is provided to amplify a weak original signal and relay it by separating a transmission antenna and a receiving arrangement antenna as far as a predetermined distance in a vertical direction and restraining an interference signal through a spare area signal processing. CONSTITUTION: A receiving arrangement antenna(101) receives a radio wave from a mobile communication network base station and an interference signal fedback from a transmission antenna together. A multi-channel receiver(102) demodulates a signal outputted from the receiving arrangement antenna(101) and converts it into a signal required for a space signal processor(103). The space signal processor(103) changes a signal outputted from the multi-channel receiver to a digital signal, processes it to restrain the interference signal, changes it to an analog signal, and outputs it. A signal modulating and amplifying unit(104) modulates the interference signal outputted from the space signal processor, amplifies it and transmits it to a transmission antenna(105). The transmission antenna(105) receives the output of the signal modulating and amplifying unit(104) and transmits a radio wave to a radio wave shade area.
