Suppose the message 111010 is to be transmitted (beginning with the leftmost bit) using CRC with generator polynomial X^4 +X+1.

Determine the entire message that would be transmitted. Show all your work. Also show how receiver will check and confirm that there is no transmission error.

Answer #1

*I've appended 4 zeros at the end of the message because the degree of the polynomial is 4.

If there is no remainder occurred at receiver side while dividing then there is no error occurred while transmission.
