This article is within the scope of WikiProject Computer science, a collaborative effort to improve the coverage of Computer science related articles on Wikipedia. If we allow any number of errors in data bits and in check bits, then no error-detection (or correction) method can guarantee to work, since any valid pattern can be transformed into any other valid pattern. The Hamming Distance Errors must not turn one valid codeword into another valid codeword, or we cannot detect/correct them.

If distinct of the set of correctable errors produce orthogonal results, the code is considered pure. 2 Detection 9. Error Detection and Correction. There are two basic methods of error control for communication, both involving coding of the messages. A code with this ability to reconstruct the original message in the presence of errors is known as an error-correcting code. International Journal of Reviews in Computing © 2009-2010 IJRIC& LLS. edu is a platform for academics to share research papers. We're upgrading the ACM DL, and would like your input. Undetected errors means the errors change a valid CW to another valid CW 2. And if these errors are not detected and corrected the result could be disastrous as the digital systems are very much sensitive to errors and will malfunction due to the slightest of errors in transmitted codes.
