Transmission power control unit and propagation path presumption device, transmission power control method and propagation path presumption method

摘要

The transmission power control unit which can reduce the excessive transmission electric power which is consumed at the time of transmitting the pilot symbol. In this device, the power control section (109) sets the transmission electrical value of the pilot signal on the basis of the quantity of repiteishiyon of the data signal. For example, the power control section (109), following to the quantity of repiteishiyon of the data signal, when synthesizing the data signal which is duplicated, sets transmission electrical value of the pilot signal, to necessary sufficient level because set point of reception quality of the communication partner is satisfied on the basis of the reception quality which is improved. The power amplification section (110) following to the transmission electrical value which is set, expands the pilot signal.
