RADIO EQUIPMENT

PROBLEM TO BE SOLVED: To improve the accuracy of transmission output power of each carrier signal in radio equipment, while reducing peak power generated in a multicarrier signal obtained by multiplexing a plurality of carrier signals.SOLUTION: A radio equipment includes a peak power reduction unit and an output power correction unit. The peak power reduction unit reduces a carrier signal gain before multiplexed, according to a peak power generated in multicarrier signals obtained by multiplexing a plurality of the carrier signals. The output power correction unit corrects carrier signal power before multiplexed, using a power correction value according to an occupied bandwidth of the multicarrier signals.SELECTED DRAWING: Figure 1 【課題】無線装置において、複数のキャリア信号を多重させたマルチキャリア信号に生じるピーク電力を低減しつつ、各キャリア信号の送信出力電力の精度を向上させる。【解決手段】無線装置は、ピーク電力低減部及び出力電力補正部を含む。ピーク電力低減部は、複数のキャリア信号を多重させたマルチキャリア信号に生じるピーク電力に応じて多重前の前記キャリア信号の利得を低減する。出力電力補正部は、マルチキャリア信号の占有帯域幅に応じた電力補正値を用いて多重前のキャリア信号の電力を補正する。【選択図】図１
