Method and apparatus for detecting oscillations and WiBro repeater having the same

摘要

Disclosed are a method and apparatus for detecting minute oscillation in a WiBro repeater, and the WiBro repeater having the same. The method of detecting minute oscillation in a WiBro repeater includes: calculating an autocorrelation value of an input signal inputted to the repeater; calculating energy of the input signal; calculating the amount of oscillation by dividing the autocorrelation value by the energy; and comparing the amount of oscillation with a predetermined threshold value to determine whether or not the minute oscillation occurs in the repeater.
