<p>In a radio communication system capable of autonomously determining, at new installation thereof, a spreading code to be used by its own station, a CDMA base station facility includes storage means (5) for storing therein all candidates of spreading codes available to base stations of the system, base station signal receiving means (2) for receiving signals sent from its neighboring base stations, correlation value calculating means (3) for calculating correlation values between the received signals from the neighboring base stations and the spreading codes stored in the storage means, comparing means (7) for comparing the calculated correlation values with each other, and spreading code selecting means (8) for selecting in accordance with a result of the comparison a kind and/or a phase of spreading code to be used by the own station. When installed at a new place, the facility receives signals from its neighboring base stations and autonomously selects spreading codes and/or phases of spreading code not used in its periphery to set a spreading code of the own station. <IMAGE></p> |
