Hello,
I am new MATLAB user, and now I want to show effect of group delay on QAM
I found simple code for QAM now I want to add Group delay to this code?
1:Is it possible to add group delay to my code?
2: Anyone have code that show group delay?
3:phase y group delay Page no. 14 show effect of group delay this is what I want.
Please help me ,

PHP:
clc;
clear all;
M=32;
x=RANDINT(100e3,1,M);
y=modulate(modem.qammod(M),x);
ynoisy=awgn(y,27,'measured');
%%I think here we should have group delay??
scatterplot(ynoisy),grid;
z=demodulate(modem.qamdemod(M),ynoisy);
figure (2);
subplot(2,1,1);
stem(x(1:10),'filled'),grid;title('transmitted data')
subplot(2,1,2);
stem(z(1:10),'filled'),grid;title('received data');
[num ty]=symerr(x,z);2: Anyone have code that show group delay?
