int_state.m

用Matlab仿真turbocode的算法

function int_state = int_state(bin_state,form)
% To convert a row vector of m bits into a integer (base 10)

[dummy,m]=size(bin_state);

for i= 1:m
   vect(i)=2^(m-i);
end

x=bin_state*vect';


switch form
    case 'unipolar'
        int_state=x;
    otherwise
        int_state=-(x-(2^m-1))/2;
end
