Abstract
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.
Claims15
A system for detecting a victim signal in an ultra wideband communication system, the system comprising:
- a fast Fourier transform unit that performs fast Fourier transform of a received signal including a plurality of time symbols to output a signal including a plurality of frequency symbols;
- a DFL (Detection Algorithm For Low Signal Noise Ratio) processor that checks and detects the presence of a victim signal in a first signal corresponding to a first region of the input fast-Fourier-transformed signal;
- a monitor that monitors an error signal generated based on a signal obtained by performing channel compensation on the fast-Fourier-transformed signal and a signal obtained by performing symbol determination on the channel-compensated signal;
- and
- a DFH (Detection Algorithm For High Signal Noise Ratio) processor that checks and detects the presence of a victim signal in a second signal corresponding to a second region of the error signal.
A method for detecting a victim signal in an ultra wideband communication system,
- performing fast Fourier transform of a received signal including a plurality of time symbols to generate a signal including a plurality of frequency symbols;
- determining the presence or absence of a first signal in a first region of the signal including the plurality of frequency symbols, and, if a first signal is present, detecting the first signal as a first victim signal;
- generating an error signal based on the signal including the plurality of frequency symbols;
- and
- receiving the error signal, determining the presence or absence of a second signal in a second region of the error signal, and, if a second signal is present, detecting the second signal as a second victim signal.
