PROBLEM TO BE SOLVED: To provide a transmitter-receiver for compensating distortion of a transmission signal with a simple configuration. SOLUTION: This transmitter-receiver is provided with a modulating part for modulating a transmission signal to be transmitted, a power amplifying part for amplifying the transmission signal modulated by the modulating part, a transmitting part for transmitting the transmission signal amplified by the power amplifying part to the outside, a selecting part for selecting and outputting either a reception signal received from the outside or the transmission signal amplified by the power amplifying part, a receiving part for receiving the transmission signal or the reception signal outputted by the selecting part, and an operating part which is connected to the receiving part, measures distortion of the transmission signal when the receiving part receives the transmission signal and demodulates the reception signal when the receiving part receives the reception signal. The modulating part corrects modulation of the transmission signal on the basis of the distortion of the transmission signal measured by the operating part. COPYRIGHT: (C)2004,JPO&NCIPI
