Jitter Resistant Ultra Wideband Pulse Generation Based on Wavelet

This paper proposes a novel method for constructing UWB pulses based on Daubechies wavelets. The constructed pulse, while meeting the FCC mask requirements insures minimum interference with WLAN by introducing a notch at 5GHz in its spectrum and provides good performance in the presence of timing jitter. The proposed pulse shaping method is based on linear combination of Daubechies wavelets. The performance of the pulse in a Additive White Gaussian Noise (AWGN) channel and multipath channel with different amounts of timing jitter is simulated and is found to be better than that of Gaussian pulse when timing jitter is high.
