Re: PHASE ESTIMATION
what u mean by change the phase??
and u r doing it in baseband right i assumed..it can be done easily by V&V algorithm, angle(sum(x(t).^M)), where x(t) is the complex received signal. The more symbols of x(t), the more accurate the phase estimated.
Or if you have pilot symbols, u can get better result by doing this
angle(sum(x(t)p*(t))) where p(t) is the complex pilot symbols.
Hope it help. Maybe you can tell me what you r doing then we can exchange more information and ideas.
