I want to generate the pulse train which consists of guasepulses with different bandwidth. Can anyone help me? This is the code that I have

warning('off')

clc

clear

fs = 1e6;

Tr=1*10^-3;

Trs = zeros(1, Tr*fs);

idxdelay=4;

bandwidth = 2:20000:62000;

multisignal = []; %initialize an empty array to contain the final multisignal

xi = zeros(1, idxdelay);

bandwidth = bandwidth(randperm(length(bandwidth)));

f=25*10^5;

fx= @(y,t) (1-cos(2*pi*f*t/y)).*sin(2*pi*f*t).*(t<(y/f));

for c=1:idxdelay

t=linspace(0,2*bandwidth(c)/f,500);

x =fx(bandwidth(c),t);

xi(c) = norm(x);

multisignal=[multisignal x Trs];

%figure(1),hold on;

end

plot(multisignal)

Hi,

The function gauspuls can be used to generate Gaussian pulses. According to the script provided, you are generating sinusoidal pulses with varying bandwidth. Replacing the sinusoidal function with the Gaussian pulse function can generate a Gaussian pulse train. You can refer to the following code snippet for more information:

clc
clear
fs = 1e6;
Tr=1*10^-3;
Trs =  zeros(1, Tr*fs);
idxdelay=4;
bandwidth = 2:20000:62000;
multisignal = []; %initialize an empty array to contain the final multisignal
xi = zeros(1, idxdelay);
bandwidth = bandwidth(randperm(length(bandwidth)));
f=25*10^5;
frac_bandwidth = bandwidth/f;
for c=1:idxdelay
t=linspace(0,2*bandwidth(c)/f,500);
x = gauspuls(t,f,frac_bandwidth(c));
xi(c) = norm(x);
multisignal=[multisignal x Trs];
%figure(1),hold on;
end
plot(multisignal)
