PURPOSE: A method for forming distributed antennas in a simulcasting system is provided to optimize the installation of the distributed antennas upon simulcasting, so as to optimize a transceiving characteristic of a mobile terminal. CONSTITUTION: Signals of a mobile terminal(500) received in plural distributed antennas(410,420) are transmitted to a CBS(Center Base Station)(100). The difference of paths between the mobile terminal(500) and the distributed antennas(410,420) and the square root of the difference between the plural distributed antennas(410,420) are extracted from the transmitted signals. The path difference and the square root of the difference between the distributed antennas(410,420) are multiplied, and a multiplied value is divided by a light velocity, to calculate a signal delay time between the distributed antennas(410,420). And the minimum installation distance between the distributed antennas(410,420) is calculated from the calculated signal delay time.
