- % 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 )

- else
- r(i)=1;

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