Abstract

PURPOSE:To compensate the loss due to rain fall for outgoing line, by performing low-speed time division multiplex connecting communication in common to the time slot location of a frame every carrier and inhibiting the burst location directed to the same station for the same time slot. CONSTITUTION:Radio stations 3-6 make a low-speed time division multiplex connecting communication having a common frame every band and a satellite relay devide 2 split into a plurality of frequency bands. Each radio station transmists the burst of the same level when it is fine. Further, if it rains 3' in a radio station 3, the transmission power of the burst from other stations to the station 3 is increased to the level at raining to compensate the attenuation in the outgoing line, and the lowering in the level reaching the relay device 2 can be avoided by increasing the burst power transmitted from the station 3 to the other stations. Thus, since the power for >=2 stations is not increased at the same time, the split loss of the power margin and the production of cross modulation can be avoided for stable communication.
