The following questions deal with CRC error detecting code. Given a message M = 110100, determine the CRC using the polynomial P = x3 + 1. What is the transmitted message T? Perform the error checking at receiving end.
CRC error detecting code. Thanks
The polynomial P will be 1001. The transmitted message will have a remainder 10. This remainder will also be the value of the CRC function.
The validity of a received message can easily be verified by performing the above calculation again, this time with the check value of 10 is added instead of zeroes. The remainder should equal zero if there are no detectable errors.
