<p>A transmitting apparatus includes a plurality of antenna elements (101,1021 - 102N), a user signal output unit (203) in a user signal processing unit (107), calibration signal generation units (1061 - 106N), antenna signal processing units (1051 - 105N), and total transmission power measuring units (1121-112N). The user signal output unit (203) weights a user signal by an antenna weight and outputs it to each antenna element. The calibration signal generation units (1061 - 106N) output calibration signals to be used to detect the characteristic of a transmission path. The antenna signal processing units (1051 - 105N) provided in the transmission path execute spread modulation and multiplexing for the user signal and calibration signal, and output a multiplexed signal. The total transmission power measuring units (1121 - 112N) measure the value of the total transmission power of the multiplexed signal to be transmitted from each antenna element, on the basis of the multiplexed signal input from the antenna signal processing units (1051 - 105N). An antenna weight correction unit (202) executes a correction operation on the basis of the value of the total transmission power.
