Abstract

PURPOSE:To receive electromagnetic waves of a base section at a mobile station without interference, by using the same transmission frequency at all the base stations and communicating by selecting only the base stations outputting a demodulation signal with the best S/N for communication. CONSTITUTION:A control station 3 is provided with an S/N discriminator 5 and a controller 6, demodulation output terminals 2a1-2n1 of base stations 2a-2n are connected to the discriminator 5, and modulation input terminals 2a2-2n2 of the base stations 2a-2n are connected to the controller 6. The S/N discriminator 5 discriminates the base station transmitting signals with the best S/N out of input signals from a plurality of base stations. The controller 6 selects and connects the corresponding base station based on the discriminated output signal of the discriminator 5.
