  • Parity-check matrix — In coding theory, a parity check matrix of a linear block code C is a generator matrix of the dual code. As such, a codeword c is in C if and only if the matrix vector product Hc=0. The rows of a parity check matrix are parity checks on the… …   Wikipedia

  • Low-density parity-check code — In information theory, a low density parity check code (LDPC code) is an error correcting code, a method of transmitting a message over a noisy transmission channel. [David J.C. MacKay (2003) Information theory, inference and learning algorithms …   Wikipedia

  • Low-Density-Parity-Check-Code — Low Density Parity Check Codes, auch als LDPC oder Gallager Codes bezeichnet, sind lineare Blockcodes zur Fehlerkorrektur.

  • 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
