Let the message be M : 1001 0001   and the generator function is G : 1001

Solution :

CRC sender

            <u>                                     </u>

1001     | 1001  0001  000

           <u>  1001                             </u>

           <u> 0000  0001             </u>

                        1000

            <u>            1001             </u>

                        0001  000

                             <u>    1 001  </u>

                                 0001

Here the generator is 4 bit - 1, so we have to take three 0's which will be replaced by reminder before sending to received--

eg    1001  0001  001    

Now CRC receiver

                <u>                                     </u>

1001         | 1001    0001   001

                <u> 1001                           </u>

                 0000 0001

                       <u>     1001                  </u>

                            1000

                          <u>  1001              </u>

                            0001  001

                    <u>        0001  001      </u>

                                   0000
