Title: Radio equipment
Inventor: KIMURA YOKO
IPC: H04B1/04
Filed: 2011-02-04
Abstract: PROBLEM TO BE SOLVED: To perform interruption communication reducing an influence on established RZSSB communication.SOLUTION: In the interruption communication, a switch 10 switches off an input of a reduced carrier wave, whose carrier generated by an oscillator 84 is attenuated in an attenuator 85, to an adder 86. By this, an A/D converter 82 converts a voice input from a microphone 81 into an analog signal, and an SSB modulator 83 modulates the analog signal into an SSB signal with the carrier generated by the oscillator 84. A D/A converter 87 converts the SSB signal into a digital signal without the reduced carrier wave being added in an adder 86, and a transmission RF circuit 88 converts the digital signal into an RF signal to transmit it from an antenna 89. In radio equipment on a receiving destination, because the carrier is not added to the SSB signal which is received as an interruption signal, the magnitude of a carrier in the established communication with other radio equipment is not varied, so that the magnitude of demodulated voice can be maintained substantially constantly without producing a beat disturbance.
