The conjugate of Lag and lead terms

You have estimated the number of the complex coefficients to be
n= MP+2(P-1)MM2
where P: the order number, M: Memory length, M2: lag depth
if you use IQ compensation then,
N=2n
if you use Dc term then,
N=2n+1
In the IQ compensation section, you haven't added the conjugate of Lag and Lead terms. You need to add them hence the total number of N=2n+1. else the total number of coefficients will be N=2MP+ 2(P-1)MM2

NN-based DPD training

If I want to build my own Neural Network-based DPD, Do I need to perform any preprocessing either for the input or output of PA? or just use PA_out as input and PA_in as the output for the NN model during training?

Synchronization step

I can't understand the idea behind these mathematical equations?! the methodology ?!
%Set up an LS estimation for figuring out a subsample delay.
X = [y [0; y(1:end-1)]];
coeffs = (X'*X) \ (X'x);
y = Xcoeffs;
