Re: UWB Gaussian Polycycles

Started by tayyar guzel March 4, 2004
Hi Divya,

I don't know of any other way to generate gaussian
polycycles, nonetheless, I can tell you how you can
use matlab's built-in functions to generate four
monocycles. Here it is: N ; n= 0:N-1; fc>9; fsE9;

% here is your data, just play with it, see what
happens
data = [1 1 -1 1];

%3GHz UWB Gpolypulses trains in the time domain with
pulse intervals (PRI) of 100nS.
D = [0 1 2 3]' * 1e-7; %Pulse delay time (100nS)
tc = gmonopuls ('cutoff',fc); %width of each
pulse(0.33nS)
t = 0 : 1/fs : 3000*tc; %signal evaluation time

%this is where we actually generate the pulse train
yp = pulstran (t,D,'gmonopuls',fc);

plot(t,yp);
grid;
xlabel ('Time in nanoseconds'); wish you good luck,
TayyaR.
