FA SELECTION TYPE RF REPEATER AND REPEATING METHOD THEREOF

摘要

PURPOSE: A frequency selection type wireless repeater and a radio relaying method thereof for interrupting the signal of frequency band are provided to selectively amplify FA by searching FA accroding to a mobile communication protocol. CONSTITUTION: A down-converter unit(103) converts wireless signal into the digital base-band signal. A frequency adjusting unit(109) obtains the signal-noise ratio about a plurality of FAs based on the digital base-band signal transformed in the down converter. The wavelength control unit detects the first FA in which the signal-noise ratio is maximum. The wavelength control unit outputs the signal of the first rank FA. An up-converter unit(107) converts the signal outputted in the wavelength control unit into the analog wireless signal. A second antenna(105) transmits the radio signal transformed in the up converter to the terminal.
