摘要
A control for varying a maximum transmission power of a transmitter according to a propagation loss or a distance between the transmitter and a receiver is made possible to reduce deterioration of a user capacity to a minimum. In a wave propagation loss measurement section (209), a calculation is performed on the basis of an amplification factor of a reception amplifier (211), amplitude information and a base station transmission power information of a reception baseband signal to calculate a wave propagation loss of a reception signal, thereby estimating a propagation loss of transmission signal. The wave propagation loss information is inputted to a maximum amplification amount designation circuit (208) to decide a maximum amplification factor. The maximum amplification amount designation circuit (208) adjusts a maximum transmission power of the transmission signal by designating the decided maximum amplification factor to a transmission amplifier (204).
