A wireless communication system has a transmitter and a receiver. The transmitter includes a transmission-data-processing device that generates items of data for a first series and items of data for a second series, a transmission-processing device that generates transmission signals for each series based on these items of data, and a wireless-signal-transmitting device that transmits the transmission signals generated by the items of data for the first series and the items of data for the second series as wireless signals of an anti-clockwise polarized scheme and of a clockwise polarized scheme, respectively. The receiver includes a wireless-signal-receiving device that receives the wireless signals of the anti-clockwise polarized scheme and the clockwise polarized scheme, a reception-signal-processing device that generates the items of data for the first series based on the received wireless signal of the anti-clockwise polarized scheme and that generates the items of data for the second series based on the received wireless signal of the clockwise polarized scheme, and a received-data-outputting device that reconfigures the generated items of data.
