 Abstract
Ultra-wideband (UWB) signal energy spreads over multiple correlator outputs due to rich multipaths, making the output of each correlator have only a small portion of the total energy. Thus, in the proposed two-stage UWB signal detection scheme for cognitive radio communication systems, the decision variable is formed by combining multiple correlator outputs, making it possible to collect the signal energy spread by the multipaths, Simulation results show that the proposed scheme can provide a gain of about 0.6 dB over the conventional schemes in various UWB channel environments.
