WIRELESS TRANSMISSION SYSTEM, WIRELESS COMMUNICATION DEVICE, AND WIRELESS COMMUNICATION METHOD
First Claim
1. A wireless transmission system comprising:
- a transmission unit;
a reception unit; and
a wireless signal transmission path configured for wireless information transmission between the transmission unit and the reception unit,wherein the transmission unit includes a first carrier signal generating circuitry configured to generate a modulation carrier signal, and a first frequency converter configured to carry out frequency conversion of a transmission-subject signal by a modulation carrier signal generated by the first carrier signal generating circuitry to generate a modulated signal,wherein the transmission unit is configured to transmit the modulated signal to the wireless signal transmission path, andwherein the reception unit includes a second carrier signal generating circuitry configured to generate a demodulation carrier signal locked with the modulation carrier signal generated by the first carrier signal generating circuitry through injection of a signal received through the wireless signal transmission path, and a second frequency converter configured to carry out frequency conversion of the modulated signal using a demodulation carrier signal generated by the second carrier signal generating circuitry.
