I'm trying to implement a QPSK burst modulation and demodulation through a channel and I'm now considering the synchronization part.
I've read that Barker sequence were excellent option for this as their autocorellation looks like a dirac.
So far I know that they're composed of
-1 and that the longest found is 13 characters long.
My question is the following:
Is there some adaptation of a Barker sequence for QPSK to make use of
the complex representation or do you simply send a classic sequence
-1 while you could use also
