% initialize stuff to do joint channel and data estimation for x4.m problem
% using alternating LLSQ solutions for A and h
%
% This method does not use the Viterbi algorithm.

% initial channel coefficients estimate
%
%  FIR = zeros(size(FIR));
%  FIR(1) = 1;

  FIR = FIR_save; % .* (1 + 0.1*rand(size(FIR))); % random 10% perturbation from true coefficients

%  FIR(1+Memory/2) = 1;	% with -1 instead of 1, the data solution will have reversed signs
