If the Generator Polynomial is 1001, What is the 3-bit CRC for the Message 1100 1001?
What is the 3-bit CRC that will be appended at the end of the message 1100 1001 with a generator polynomial of 1001?
The 3-bit CRC that will be appended at the end of the message 1100 1001 with a generator polynomial of 1001 is 101.
Understanding CRC and Generator Polynomial
1 0 0 1 ) 1 1 0 0 1 0 0 1 0 0 0 1 0 0 1 ----- 1 1 0 0 1 0 0 1 ----- 1 1 1 0 1 0 0 1 ----- 1 1 1 1 0 0 1 ----- 1 0 1The remainder after dividing is 101, which is the 3-bit CRC that will be appended to the message 1100 1001.
