Question

How to make link between crc generator code and error-detecting code so that it can run smoothly?
For reference, my crc generator code is-
% The program generates CRC code for any given input message stream &
% generator polynomial
%msg=[1 1 1 0 0 0 1 1 ]
msg=input('Input Message sequence :');
%poly=[1 1 0 0 1 1]
poly=input('Input Generator Polynomial :');
[M N]=size(poly);
mseg=[msg zeros(1,N-1)];
[q r]=deconv(mseg,poly);
r=abs(r);
for i=1:length(r)
a=r(i);
if ( mod(a,2)== 0 )
r(i)=0;
else
r(i)=1;
end
end

crc=r(length(msg)+1:end)
frame = bitor(mseg,r)
