Hello
I'm in need of some help if you please.
I have 2 sinsoidal signals with a phase shift of 2Pi/3 between them. Basically, I need to eliminate the phase shift and obtain 2 signals with the same phase. I'm looking forward to use the cross-correlation, that represents the differnce between both signals (the phase shift, in our case), to do so.
My problem is to know how to use the cross-correlation to "correct" the shifted signal by eliminating the phase shift indiquated by the cross-correlation. Which operation to use to do so?
Here is a portion of the code for further understanding :
t = 1 : 1000;
phaseshift= 2*pi/3;
s1 = sin (2*pi*t/500);
s2 = sin (2*pi*t/500+ phaseshift);
figure(1); clf;
plot (t,s1, t,s2);
Axis_x = [-length(s1)+1 : 1 : length(s1)-1];
cross_corr = xcorr(s1,s2,'coeff');
figure(2); clf;
plot( Axe_x, coss_corr,'r');
Thanks in advance
