In order for simulcast phase synchronization to be carried out autonomously by each base station, a highly accurate clock is provided in the central station and in each base station, and phase compensation is performed in accordance with time information from these clocks. As a result, simulcast synchronization that depends on the accuracy of clocks can be established, and the required synchronization accuracy can be obtained even when high transmission speeds are involved. The clocks can be corrected by a portable reference clock brought to each base station and central station site, and/or by a global positioning system installed at each base station and/or central station site. Because this invention is constituted so that each frame of paging signals transmitted by a base station is transmitted under the control of a reference clock in accordance with a preset table, it becomes unnecessary to indicate transmission times in the paging signals that are sent from the central station to the base stations, whereby base station equipment is simplified.
