  • Multidimensional parity-check code — A multidimensional parity check code (MDPC) is a simple type of error correcting code that operates by arranging the message into a multidimensional grid, and calculating a parity digit for each row and column. In general, an n dimensional parity …   Wikipedia

  • Parity (mathematics) — In mathematics, the parity of an object states whether it is even or odd. This concept begins with integers. An even number is an integer that is evenly divisible by 2, i.e., divisible by 2 without remainder; an odd number is an integer that is… …   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

  • Longitudinal redundancy check — In telecommunication, a longitudinal redundancy check (LRC) or horizontal redundancy check is a form of redundancy check that is applied independently to each of a parallel group of bit streams. The data must be divided into transmission blocks,… …   Wikipedia
