ABSTRACT:
The present invention relates to a wireless communication system which suppresses the quantity of an electric power of a carrier wave consumed in communicating by a digital data as well as it can improve the communication quality. The wireless communication system according to the present invention includes at least a signal processing circuit section and a high frequency transmitter/receiver section and it comprises controlling the timing of modulation completion by the digital data signal with the transmitting timing of the modulation carrier wave supplied from the electric power amplification section of the high frequency transmitter/receiver section and a control circuit which controls the operation of the high frequency transmitter/receiver section in transmitting the modulation carrier wave on the basis of the preceded timing of the modulation completion.
