Hi everyone.
I just want to plot the QPSK baseband spectrum from the output data of the QPSK
simulink block.
However the output of this block are the symbol coordenates in the signal space
and when I use "spectrum scope" i don't get the theorical spectrum for the
qpsk (the sinc function..).
How can I do it? Can I use the qpsk block?
thanks in advance!
