• Polynomial code — In coding theory, a polynomial code is a type of linear code whose set of valid code words consists of those polynomials (usually of some fixed length) that are divisible by a given fixed polynomial (of shorter length, called the generator… …   Wikipedia

• Convolutional code — In telecommunication, a convolutional code is a type of error correcting code in which each m bit information symbol (each m bit string) to be encoded is transformed into an n bit symbol, where m/n is the code rate (n ≥ m) and the transformation… …   Wikipedia

• Linear code — In mathematics and information theory, a linear code is an important type of block code used in error correction and detection schemes. Linear codes allow for more efficient encoding and decoding algorithms than other codes (cf. syndrome… …   Wikipedia

• Cyclic redundancy check — A cyclic redundancy check (CRC) is an error detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. Blocks of data entering these systems… …   Wikipedia
