SYNCHRONOUS COMMUNICATION SYSTEM

摘要

PURPOSE:To provide a synchronous communication system in which the increase in a delay time is suppressed when one frequency simultaneous transmission reception system is configured via a relay station. CONSTITUTION:A relay control section 1-3 is provided in a signal path between radio equipments 1-1 and 1-2 of a relay station 1 and a timing for changeover of transmission and reception between radio equipments 2, 3 at a terminal station is set in synchronism with a predetermined time slot by the relay station 1 by controlling a signal transmission time between the radio equipments A and B. Since the burst signal subjected time compression in the one-frequency simultaneous transmission reception system is directly relayed in the relay station 1 without any modification, the increase in the delay time due to repeated time compression and expansion is avoided and the communication without a sense of incongruity is attained.
