Matlab code to decode all the received words for (7, 4) LBC take any suitable generator matrix.

Code:

r=input ('enter received data r=');

h=input ('enter the transpose matrix number h=');

d=r*h;

for i=1:length(d),

    y=d(i);

    x=mod(y,2);

    d(i)=x;

end 

disp('syndrom=');

disp(d);

l=length(r);

e=zeros(1,l);

for i=1:l;

    e(i)=1;

    s=e*h;

    if s==d

        i==l;

    else

        e(i)=0;

    end

end

disp('error=');

disp(e);

c=xor(r,e);

disp('original data=');

disp(c)

Output: 

enter received data r=[1 0 1 1 1 0 1]

enter the transpose matrix number h=[1 0 0 0;0 1 1 0;1 1 0 1;0 1  0 1 ;1 1 0 0;0 0 1 0; 1 0 0 1]
