Abstract
A wireless communication system that communicates by an electromagnetic wave includes a first wireless device that includes a transmission rotationally polarized wave frequency generator for giving a rotation period to a polarized wave of the electromagnetic wave to be transmitted, transmits a synchronization code by the electromagnetic wave of the polarized wave rotated using the transmission rotationally polarized wave frequency generator, and transmits data by the electromagnetic wave, and a second wireless device that includes a reception rotationally polarized wave frequency generator for giving a rotation period to the polarized wave received in a reception of the electromagnetic wave, calculates transmission timing of the synchronization code included in the received electromagnetic wave of the polarized wave rotated using the reception rotationally polarized wave frequency generator, and sets a signal included in the received electromagnetic wave, as data based on the calculated transmission timing.
