Hello everyone,
I try to simulate PSK modulation and demodulation without channel model to
calculate BER. The flow graph as shown below.
From File Source to PSK Mod is working, I can see the constellation even
with ISI. But after PSK demod there's no output.
Is there's anything wrong
Hi,
do you know if the default PSK Demodulation block does any frecuency correction
or time recovery?
After running some tests, I have noticed that when I use a Channel Model
between PSK mod and PSK demod, I successfully decode my data even I have a
small frecuency offset or time offset
Thank you Karl!
