发明名称 BOOSTER DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To provide a device to be operated with an amplification rate of not less than inter-antenna connection quantity by providing a conversion circuit of control information on a frequency, changing the control information on the frequency and making a received frequency to be different from a re- transmission frequency and relieving the limiting conditions on the amplification rate. SOLUTION: Only control information on a frequency is changed in frame signals, taken out of reception demodulation parts 2 and 8 and frame signal extraction parts 3 and 9. Other information is inputted to frame signal generation parts 5 and 11, so that they are sent out as they are. The changed frequency is designated to modulation/transmission parts 6 and 12, and the modulation/transmission parts 6 and 12 execute modulation with the changed frame signal and execute retransmission. Control information requiring changes concerns an informing channel, an individual channel and a call channel in control channels on the frequency. Since the device has a conversion part of control information regarding the frequency, repeating of amplification with converted frequency is made possible.</p>
