error-correcting code

error-correcting code A code that is designed for channel coding, i.e. for encoding information so that a decoder can correct, with a high probability of success, any errors caused in the signal by an intervening noisy channel.

Error-correcting codes may be block codes or convolutional codes, and in either case are employed in a forward error-correction system. The most common error-correcting block codes are the Hamming codes, Bose–Chaudhuri–Hocquenghem (BCH) codes, Reed-Solomon (RS) codes, simplex codes, and the Golay (23, 12) code.

Since errors may be corrected by detecting them and requesting retransmission, the process of error correction is sometimes taken to include backward error-correction systems and, hence, error-detecting codes.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

The Chicago Manual of Style

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
