COMMUNICATION DEVICE, DISTORTION COMPENSATION CIRCUIT, AND DISTORTION COMPENSATION METHOD

摘要

A transmission circuit sends a signal transmitted from a signal processing part to a port. A reception circuit sends a signal received from the port to the signal processing part. A waveform monitor monitors the waveform of the signal transmitted from the transmission circuit to the port, thereby generating a feedback signal. A switch part connects the feedback signal from the waveform monitor to the reception circuit in transmission timing. The signal processing part compares the transmitted signal with the feedback signal of the transmitted signal.
