Excessively worry and property to radiation for the people coordinates being continuously increased of difficulty, and construction cost is climbed to a higher point day by day, causes
The construction of mobile communication base station is more and more difficult, and merely rely on base station equipment carry out network seamless continuously
Cover hardly possible realization, so scientific research personnel proposes the scheme of repeater in this context.
Repeater is positioned at the covering fringe region of base station, extends to the coverage of base station, and repeater
Composition includes two set receiving-transmitting chains, and its operation principle is: downlink, the wireless communication of reception base station, repeater
Number, it is forwarded to terminal after filter and amplification；Up-link, repeater receives the wireless signal of terminal, and filtering is put
It is forwarded to base station after great.

Digital to analog converter (Digital to Analog Converter, DAC) and PLC technology unit (Field-
Programmable Gate Array, FPGA) etc. device.According to the difference of duplex mode, for opening after antenna
Close (Switch) or duplexer (Duplexer).
The specific works flow process of this repeater is: when descending, and the wireless signal from base station enters through returning antenna
Enter Switch/Duplexer, then through devices such as LNA, Gain, enter FPGA through ADC, after process
Signal through DAC digital to analog conversion, after launch covering terminal through PA, incoming end antenna etc.；Up
When, the wireless signal carrying out self terminal enters Switch/filter through incoming end antenna, then through LNA, Gain
Deng device, enter FPGA through ADC, the signal after process through DAC digital to analog conversion, after through PA,
Passback antenna etc. is launched to base station.
