<P>PROBLEM TO BE SOLVED: To provide a radio repeating apparatus which has reduced circuit scale while maintaining frequency utilization efficiency. <P>SOLUTION: The radio repeating apparatus 100 includes a transmission section 74 which outputs as a transmission signal, a main signal for transmitting transmission data and an auxiliary signal for transmitting status information of radio equipment used for repetition, and a reception section 76 which acquires transmission signal from another station and separates it into a main signal and an auxiliary signal. The transmission section 74 includes an IQ separator 11, an IQ distributor 12, a complex multiplier 13, a complex vector generator 14, an in-phase adder 15, a low-pass filter 16, a D/A converter 17, a quadrature modulator 19, a synthesizer 20, and an amplifier 21. The reception section 76 includes an amplifier 31, a distributor 32, a quadrature demodulator 33, a capacitor 34, a low-pass filter 35, an A/D converter 36, and an IQ synthesizer 37. <P>COPYRIGHT: (C)2008,JPO&INPIT |
