Question

Consider a pair of independently modulated signals, ue(t) ΣΝ1b [n]p(t-n) and us(t) bnlp(t -n), where the symbols beln), b, nl are chosen with equal probability to be +1 and -1, and p(t) Io.1](t) is a rectangular pulse. Let N 100 (1.1) Use Matlab to plot a typical realization of ue(t) andu(t) over 10 symbols. Make sure you sample fast enough for the plot to look reasonably "nice."

Answer 1

ze=zeros(100,1);
for i=1:100
    ze(i)=1-2*binornd(1,0.5);
end
c=ze;
T=4e-5;
t= linspace(-5*T,5*T,81);
h=ones(1,8);
u_c=conv(c,h,"same");
u_s=conv(c,h,"same");

so the plots are are the following

a)u_c

4 2 2 -4 40 60 80 100 20

b)u_s
