Abstract
The present invention addresses the problem of providing a signal process in which a countermeasure against eavesdropping over a physical layer in a wireless communication is performed. An optical signal generation unitgenerates, as an optical signal, multivalued information that is in a multivalued state and is based on prescribed data. An E/O conversion unitconverts the optical signal to an electrical signal. An optical signal amplification unitamplifies the optical signal. An O/E conversion unitconverts the optical signal to an electrical signal. A radio wave transmission unittransmits, as a radio wave, the multivalued information converted into the electrical signal. The problem is solved thereby.
