Abstract
A modulator converts an inputted data to be transmitted into a septenary data, modulates a carrier by the converted data, and transmits the modulated carrier via an antenna. A demodulator demodulates a received data supplied from the antenna into an octonary data, which is converted into a septenary data. According to the structure, a vector representing the modulated carrier is prevented from passing a “O” point when a phase shift of the modulate carrier occurs.
