I am currently studying for an exam and trying to check a message (binary) for errors using a polynomial, I would like if somebody could verify that my results below are (in)valid.
Thanks.
Message: 11110101 11110101
Polynomial: X4 + x2 + 1
Divisor (Derived from polynomial): 10101
Remainder:111
Result: There is an error in the above message?
Also, I had a link to an online calculator that would do the division but can't relocate it, any links to a calculator would be greatly appreciated.
Thanks.
