%
%    Implements an adaptive RLS Lattice Backward Prediction 
%    Error Filter with filter input x(n) and output e(n).
% 
% Input Parameters:: 
%    ff  : last autocorrelation of forward prediction error (f)
%    bb  : last autocorrelation of backward prediction error (b)
%    fb  : last cross-correlation of f and b 
%    b   : last backward prediction error vector
%    a   : forgetting factor
%    x   : newest input sample x(n)
%
% Output parameters::
%    ff  : updated autocorrelation of forward prediction error 
%    bb  : updated autocorrelation of backward prediction error 
%    fb  : updated cross-correlation of f and b 
%    b   : updated backward prediction error vector
%    y   : linear combiner output 
%    e   : forward prediction error 
%    kf  : updated forward lattice coefficients kf(n)
%    kb  : updated backward lattice coefficients kb(n)
%    c   : equivalent transversal backward predictor coefficients.
