Wireless communication system and system using same

Abstract

Provided is a wireless communication system that achieves high-reliability communication between a transmitter and a receiver. Specifically, the wireless communication system includes: a transmitter that transmits a carrier wave with rotational polarization on which a strongly correlated code is superimposed; and a receiver that uses the strongly correlated code in the reception polarized wave from the transmitter to establish synchronization between the transmitter and the receiver, wherein the receiver receives signals in a plurality of different polarized waves, establishes synchronization between the transmitter and the receiver for the plurality of reception polarized waves using correlation values between the received signals and the strongly correlated code corresponding to the reception polarized waves, compares the correlation values to a threshold to extract a specific reception polarized wave and a received signal corresponding to the polarized wave, calculates transmission polarization angles from shifts in synchronization timing, and separates or selects the signals transmitted in different propagation paths using specific reception polarized waves corresponding to the plurality of transmission polarization angles and the received signals corresponding to the polarized waves.
