% DESCRIPTION
%
% CELP vocoder simulation, including analysis, transmission, synthesis,
% and graphical user interface (GUI).
%
% DESIGN NOTES
%
% This simulation has been ported from the NSA version of CELP, CELP 3.2a,
% available in source code form via Internet anonymous [e-mail].
% All MATLAB code has been optimized ("vectorized") to run in the
% MATLAB environment where possible.  For example, all for loops have
% been replaced with array-wise or column/row-wise operations,
% where possible. In addition, many operations which were done by
% loop based summations, such as filtering, have been replaced with
% calls to simple MATLAB built in functions.  These include
% operations such as filter() and median(). With some work, it is probably
% still be possible to optimize some sections further.
