Well, you asked for "and other modulations", so I gave you one where
phase synchronization is possible with simple control loops.
Synchronization of 16QAM is... nontrivial. I've just discussed this
with my favourite officemate.
In practical systems, it's very likely that you'd simply send a
Hello Marcus, and all,
Thanks for the response,
I am reading the PSK example you told me, nevertheless y am not so sure it
applies also for 16QAM...i understand that Costas Loop, does not work with
16 QAM.
Is there any flowgrpah for a complete 16QAM modulator/demodulator?
Kind regards.

Hello Marcus,
Thanks for the response,
I am not using an attenuator, because i font have one , i am only with my
cable, but i have meassured the Power before connecting to the RX in my
USRP, so it wont be bigger than the threshold of the USRP.
Thanks for the info, is there any guide where i can
Hi Luis,
I hope you're using an attenuator with a cable or antennas in your
feedback, not to risk damaging your receiver!
What you need to do to get a similar constellation is the whole dance
that is taught in your average digital communication basics lecture:
Synchronization in time, and phase
