Abstract
A transmitter includes: a first transmission block that generates a first radio wave having an information signal modulated thereon and having a plane of polarization that rotates; and a second transmission block that generates a second radio wave having the information signal modulated thereon and having a plane of polarization that is fixed. A receiver includes: a first receive section that demodulates a first radio wave having an information signal modulated thereon and having a plane of polarization that rotates; and a second receive section that demodulates a second radio wave having the information signal modulated thereon and having a plane of polarization that is fixed. The receiver restores the information signal on the basis of the result of reception by the first receive section and the second receive section.
