source Matlab traites the UWB

% A: pulse amplitude [V]
% chip_span: %how many chips before and after
% alpha: determines the pulse width
% TC
% samples_per_chip

function [monopulse,t] = get_monopulse(A,chip_span,alpha,TC,samples_per_chip)

%pulse shaping

%this is needed if the pulse shape is not exactly zero outside the
%boundaries of one chip, 0.5 = the pulse shape has a duration of exactly
%one chip, nothing will be cut out later.

Tmin = -chip_span * TC;                     % Lower time limit
Tmax = chip_span * TC;                      % Upper time limit
t=linspace(Tmin,Tmax,smp);        % Inizialization of the
                                  %  time axis

monopulse=gaussian_pulse(A,t,alpha); %get the monopulse
%monopulse = monopulse./norm(monopulse); %normalize it
