Improved Method of Generating UWB Pulse
The choice of pulse is crucial for ultrawide-bandwidth (UWB) communication system, bescause it will affect the power spectral density of emission signal. In most cases, the spectrum of single pulse waveform do not meet the federal communication committee (FCC) emission mask.The text proposes that the optimal waveform can be got through a linear combination of different derivatives of the Gaussian pulse so that it can approach the standard of emission mask in the whole band.
