I am trying to learn signal processing and digital pre-distortion.
I am currently trying to auto correlate the input signal and from this I make a matrix. I then get the coefficients for this matrix and use them with a LUT to help pre-distort the signal. I am having difficulty understanding what these coefficients represent? Why are they useful when added to the LUT. So the coefficients are used as a weight in those LUTs. Can anyone give me a pointer?
Same goes for the cross-correlation with the feedback, what do the coefficients from that vector represent?
Thanks for any help.
