I have attached a part of the simulink model and code through which the gaussian pulse is being generated and also the image of scope after the bpsk transmitter. I want to generate more gaussian pulses periodically. So instead of just a single pulse in the scope maybe 4-5 (or any number of pulses).

This is the code i've used to generate the gaussian pulse.

function y = fcn(t,A)

%#codegen

t1=.5E-10;%pulse width(0.5 nanoseconds)

x=(t/t1)*(t/t1);%x=(t^2/t1^2)(square of (t/t1)

%A=1;%positive value gives negative going monopulse;neg value gives %positive going monopulse

y=A*(1/(sqrt(6.28)*t1))*(1-x).*exp(.5*(-x));

I tried using the math function(mod) so that the signal can be repeated but was unsuccessful.
