hamming distance

In general, the hamming distance between two strings of equal length measures the number of errors that transformed one string into the other. CAN provides a hamming distance of 6 (theoretical value for CAN networks). This indicates that five randomly distributed bit failures can be detected. In addition burst errors of up to 15 bit can be detected. CAN provides no bit correction mechanisms.
