Summary:
Since radio channels available have been assigned to traditional narrowband communication systems the only solution to establish new radio communication links is the frequency reuse. This has to be achieved without causing interference in the conventional radio systems. Ultra WideBand (UWB) radio uses extremely wideband wavelets to decrease the Power Spectral Density (psd) of radiated signal. In this paper a new demodulation technique called near-coherent demodulation is proposed for UWB systems. Closed form expressions are derived for the Bit Error Rate (BER) of the new demodulator. Results of simulations validate the derived theoretical BER performance of near-coherent detection.
