Abstract

A preprocessor for ultra-wideband (UWB) communications using impulse radio is proposed. The received UWB signal is divided into subband signals, which can be individually processed and recombined before demodulation of the signal. Perfect reconstruction of the pulses via analog subband processing is achieved. The division of subbands is flexible and the number depends on the number of frequency bands that requires processing. Only the subbands that require processing need to be digitized. The application of the preprocessor to interference cancellation is also demonstrated.
