Hello Everyone,
I was wondering if anyone out there would know any kind of phase synchronisation techniques used in satellite communication.
Thanks in advance

With that minimum amount of information one can only give you a very general answer. The standard way to make one thing track another is with "degenerative" (aka negative) feedback. For phases, then, one would use a phase-feedback system, more commonly known as a phase-locked loop (PLL).
Since those are just words, they may not help too much by themselves. However, using them as search keywords will rapidly direct you to a large amount of information, some of which might even be useful.
The reliable Horowitz and Hill ("The Art of Electronics") can be counted upon for a good overview, I'd imagine.
carrier phase synchronization by Phase Locked loops. would that be correct ?
Are you just wanting to amplify a RF signal?
I'm thinking that you could use something like they use in a grid-tie inverter, where the 60 hz signal "opens" and "closes" a transister, which creates a new, stronger wave (or combined wave) with battery power.
Not sure how clean the signal would be, though. You may have to convert the signal into another form (like electrical pulses for a speaker) then back convert it to a similar frequency (not the same, though, because it would probably cause feedback).
well i am not doing a practical. I have been given an assignment on this topic to do research and then present. I am having problems choosing a technique as I have not studied this subject matter before.
Any kind of technique on which I can do research would be appreciated.
Thanks

Not sure if it will help. I'm not sure that a transistor can switch on and off fast enough for a several gigahertz signal, and even then the signal might lose quality.
