Can someone teach me how to create a USB pulse with Matlab?
% Pulse parameters
pulse.type = 0; % 0 = Gaussian
pulse.width = 1.4e-9; %
[pulse.xt, BW10dB] = uwbPulse(pulse.type, pulse.width, Fs);
txParam.pulse = pulse;
I need to write that function "uwbPulse" given pulse.type, pulse.width and Fs.
Thanks.

Fs is defined somewhere else, like: Fs = 1/(0.4e-9);

I wrote email to his last publicly available address (a phd student @stanford) - but got no reply.

You can use this equation G(x)=1/√(2πσ^2 ) e^((-x^2)⁄2) σ^2 This pulse is often used in UWB systems because its shape is easily generated.
