Abstract

Fixed radio equipment serving as a base station includes a transmitter, a plurality of antennas, and a selective control circuit. The antennas are spaced apart from each other by a distance which minimizes a correlation of interferential fading. The transmitter modulates a carrier by identical signals to be transmitted during periods associated in number with the antennas and feeds the resulting bursts of the carrier time-serially to a selective control circuit. The selective control circuit delivers one of the successive bursts of the carrier fed from the transmitter to one of the antennas and then delivers another burst following the above-mentioned burst to another one of the antennas. Mobile radio equipment or station has a single antenna for receiving the identical signals transmitted time-serially from the base station. The mobile station selects and outputs either one of the received signals which has higher quality than the other.
