Abstract
A DAA (Detection And Avoidance) apparatus for use in a UWB receiver includes a frequency offset unit for adding a preset frequency offset to a UWB signal including a victim signal and an FFT unit for performing a fast-Fourier-transformation on the UWB signal with the frequency offset added thereto. The DAA apparatus further includes a DAA unit for detecting a victim signal from the fast-Fourier-transformed UWB signal and, when reception power of the victim signal is higher than a predetermined reference power level, changing a communication channel for the UWB signal to avoid interference.
