I need to write a MATLAB function to estimate the best initial sampling point for demodulation of a 16-QAM.
I can do it by looking at the eye diagram, the point which at which the eye is "open", but can this be done in MATLAB?
An eye diagram can be created by just framing up your QAM signal (probably after matched filtering), where the frame length is the number of samples per QAM symbol. In MATLAB, this is very simple:
One note: the call to
