The Cyclic Redundancy Check is another form of error detection that involves use of modulo 2 arithmetic to compute a Frame Check Sequence that is added on to. I know the whole intention of using CRC is to do error detection, but I heard someone state that it can be used to do basic error correction in addition to error. Hamming distance is still the staple of error detection and correction. For example, a CRC of 16 bits needs a. CRC only allows for error detection;.
