SYSTEM FOR TREATING OSCILLATION FROM RELAY SYSTEM IN WIRELESS TELECOMMUNICATION SYSTEM AND METHOD THEREOF

摘要

An oscillation processing system in a repeater system used in a wireless communication system and an oscillation processing method thereof are provided to minimize a degrading phenomenon and distortion of a transmission signal due to oscillation in a wireless telecommunication system. A coupling unit extracts a signal outputted from a repeater system(801). A spectrum analysis unit converts a signal extracted from a coupling unit to frequency domain and analyzes a spectrum of a frequency domain(802). A spectrum detection and analysis method uses either a sweep method or the Fourier transform method. An oscillation detector performs the reverse Fourier transform in a signal analyzed in the spectrum analysis unit to convert the signal into time domain and produces an isolation by using amplitude of the signal in a time domain(803). A controller determines the oscillation state according to the produced isolation and controls a system gain according to isolation(804).
