function [ SYMBOLS , PREVIOUS , NEXT , START , STOPS ] = viterbi_init(Lh)
% VITERBI_INIT:
% This function returns the tables which are used by the
% viterbi demodulator which is implemented in the GSMsim
% package.
%
% SYNTAX: [ SYMBOLS , PREVIOUS , NEXT , START , STOPS ]
% =
% viterbi_init(Lh)
%
% INPUT: Lh: The length of the channel impulse response
% minus one.
%
% OUTPUT: SYMBOLS: Statenumber to MSK-symbols mapping table.
% PREVIOUS: This state to legal previous state mapping table.
% NEXT: This state to legal next state mapping table.
% START: The start state of the viterbi algorithm.
% STOPS: The set of legal stop states for the viterbi
% algorithm.
%
% GLOBAL: None
%
% SUB_FUNC: make_symbols,make_previous,make_next,make_start,make_stops
%
% WARNINGS: None
%
% TEST: Verified that the function actually runs the subfunctions.
