Thanks everyone. Sometimes I can be a little confusing....

Here is what I was trying to do:

I have a delay in my system that I am trying to get rid of. I use a Costa's loop for carrier recovery and have a rather large delay when measuring during calibration. I was thinking since I know the delay, I can somehow remove it by phase locking my NCO somehow. But as Dave said, it is much easier to just use some post processing in Matlab to compensate, which is what I did and it seems to work.

Thanks again
