PROBLEM TO BE SOLVED: To prevent production of a setting error by obtaining an optimum delay correction time automatically so as to set it again automatically in the case of training a high speed modem at a base station side mainly. SOLUTION: A central station 3 and a base station 4 have respectively satellite communication reception units 200, 210 and receive a pulse signal for each second. Upon the receipt of the pulse signal, the central station 3 sets at which bit location of a frame a 1-sec pulse is received to the frame as input terminal and transmits the resulting frame. Delay correction sections 100-10n of the base station 4 send data whose delay is corrected based on bit location information the moment when a succeeding 1-sec pulse signal comes to transmitters 120-12n. The timing is controlled by a control section 212. |
