Title:
送信装置、歪み補償装置及び歪み補償方法
Document Type and Number:
Japanese Patent JP5365369
Kind Code:
B2
Abstract:
A transmission device (10) includes an amplifier (101) that amplifies a transmission signal according to a voltage to be applied, an envelope detector (102) that detects an envelope signal of the transmission signal, a rate decreasing unit (103) that decreases changing rate of the envelope signal detected by the envelope detector (102), and a voltage controller (104) that changes the voltage applied to the amplifier (101) according to the envelope signal whose changing rate is decreased by the rate decreasing unit (103).
