Abstract :
This paper considers a UWB communication system that uses spectral encoding as both the multiple access scheme and the interference suppression technique. The main advantage of this technology is that the transmitted signal spectrum can be conveniently shaped to suppress narrow-band interference. The implementation of such systems considering real-time devices is examined, and its performance is analyzed in the presence of narrow-band interference. Numerical results of the system performance are presented for a UWB channel model, and for two different multipath combining schemes.
