• 32-Bit Cyclic Redundancy Codes for Internet Applications

2014-8-4u2002·u2002Unfortunately, standardized CRC polynomials such as the CRC-32 polynomial used in the IEEE 802.3 (Ethernet) network standard [IEEE85] are known to be grossly suboptimal for important applications. For example, the 802.3 CRC can detect up to three independent bit errors (Hamming Distance HD=4) in an Ethernet Maximum

2016-2-28u2002·u2002Reduced to a single check bit, Hamming codes and CRC are identical (x+1 polynomial) to parity. Both CRC and the Hamming code are binary linear codes. One significant difference is that the Hamming code only works on data of some fixed size (depending on the Hamming code used), whereas CRC is a convolutional code which works for data of any size.

2011-8-6u2002·u2002The minimum distance dmin is the smallest hamming distance between two code words. The hamming distance is the number of symbols (bits in the binary case) in which they differ. The minimum distance is closely linked to the capacity of the code to detect and correct errors and is a function of the code characteristics. An (n,k) block code is capable

In Classical CAN, a 15-bit CRC polynomial is used (x 15 + x 14 + x 10 + x 8 + x 7 +x 4 +x 3 + x 0 ). It features a Hamming distance of six. This means that five randomly distributed bit failures are detectable. The polynomial is also able to detect burst-errors up to 15 bit. However, this is only true for a fixed data length.
