Hey guys, thanks in advance,
I have this graph:
And I wish to normalize y axis , saying that maximum is 0dB. Im normalizing it like this:
maxval=max(X_QPSK_cut);
X_QPSK_cut=X_QPSK_cut/maxval;
fig=figure;
hold on
set(fig,'color','white');
plot(freq_XQPSK_cut,20*log10(X_QPSK_cut),'b','linewidth',2);
xlabel('Frequency [Hz]');
ylabel('QPSK Spectrum [dB]');
set(gca,'fontsize',fontsize);
grid on;
hold off
Is there a way of normalize the y axis , saying that max val is 0, because, if I put 0 it will say that vector is infinit, and that is true,
Thanks,

The above plot doesn't seem to represent the code (or vice versa)....if you actually normalized as the code says, the max cannot be -105 dB or whatever the max actually is on the plot.
Something's not kosher -- attach the data file as .mat file.
