Ultra-wideband (UWB) signals with a large bandwidth has some advantages like multipath immunity, low transmission power, good resolution for ranging and detecting geo locations, as well as it can resist to narrow-band interference. These signals are used for transmission in short distance with high throughput. In this paper, we have analyzed different modulation schemes for performance comparison in terms of BER with UWB Gaussian second derivative monopulse and wavelet-based monopulse. The simulation results demonstrate that wavelet-based monopulse provides better performance in comparison to the other two monopulses.
