System and method for detecting victim signal in MB-OFDM UWB communication system

摘要

To detect a victim signal in an ultra wideband communication system, fast Fourier transform of a received signal including a plurality of time symbols is performed to generate a signal including a plurality of frequency symbols, it is determined whether a first signal is present in a first region of the signal, and if a first signal is present, the first signal is detected as a first victim signal. Next, an error signal is generated based on the signal including the plurality of frequency symbols, it is determined whether a second signal is present in a second region of the error signal, and if a second signal is present, the second signal is detected as a second victim signal.
