Hello,
I mean, if a student who was graduated lately from a faculty of RF communications at a well-known university is asked the title’s question, what will be his answer?
During my MS studies, more than 4 decades ago, there were two only:
[1] Costas Loop is based on PLL and uses I-Q signals.
[2] The squaring method uses a selective filter at 2*Fc to recover (after /2) the frequency and phase of the suppressed carrier (Fc).
I ask you this question because I am not sure if, in these days, there are more universally known topologies or not. From where I live, searching on the internet is limited (restricted), due to world’s regulations. My search tells me there is no more!
Thank you for your help and time.
Kerim

By getting no reply, you tell me that the two topologies above are the only ones known at all universities around the world.
Thank you.

Thank you, Georges, for the hint.
