Title:
COMMUNICATION DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/145209
Kind Code:
A1
Abstract:
Provided is a communication device capable of suppressing deterioration of the accuracy of synchronization between a transmission side and a reception side, even if noise at a high signal level is generated on a transmission path. The communication device is provided with: an operation circuit that calculates a first phase difference between a signal point relating a received signal, and a reference point in accordance with the modulation system of the communication device; a correction circuit that corrects the phase of the signal on the basis of the first phase difference; a measuring circuit that measures noise influence which the signal received, said noise having been on the transmission path; and a control circuit that determines, on the basis of the noise influence, whether the correction circuit is to correct the phase of the signal using the first phase difference.
