PURPOSE:To eliminate the increase of unnecessary transmission power and the increase of interference to the other lines by increasing the transmission power only at the time reducing the reception level due to rainfall or the like. CONSTITUTION:When the reception level is reduced to a prescribed value or lower during bidirectional communication between radio stations and the deviation of the reception level in a reception band is zero or is about zero, a decision control part 5 decides flat fading due to rainfall or the like and transmits a control signal, which increases the transmission power of the radio station of the other party, to this radio station from a transmission part. Consequently, the transmission power is not increased at the time of only reducing the reception level like coherent fading. Thus, the unnecessary transmission power is not increased to reduce the power consumption, and interference with the other radio lines is reduced. |
