• BCH code — In coding theory the BCH codes form a class of parameterised error correcting codes which have been the subject of much academic attention in the last fifty years. BCH codes were invented in 1959 by Hocquenghem, and independently in 1960 by Bose… …   Wikipedia

• Exclusive or — The logical operation exclusive disjunction, also called exclusive or (symbolized XOR or EOR), is a type of logical disjunction on two operands that results in a value of “true” if and only if exactly one of the operands has a value of “true”. [… …   Wikipedia

• Lucas–Lehmer test for Mersenne numbers — This article is about the Lucas–Lehmer test (LLT), that only applies to Mersenne numbers. There is also a Lucas Lehmer Riesel test for numbers of the form N=k 2^n 1, with 2^n > k, based on the LLT: see Lucas Lehmer Riesel test. There is also a… …   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

• Quantum teleportation — Quantum teleportation, or entanglement assisted teleportation, is a technique used to transfer information on a quantum level, usually from one particle (or series of particles) to another particle (or series of particles) in another location via …   Wikipedia

• Group code — In computer science, group codes are a type of code. Group codes consist of n linear block codes which are subgroups of G^n, where G is a finite Abelian group.A systematic group code C is a code over G^n of order left| G ight|^k defined by n k… …   Wikipedia

• Interaction information — The interaction information (McGill 1954) or co information (Bell 2003) is one of several generalizations of the mutual information, and expresses the amount information (redundancy or synergy) bound up in a set of variables, beyond that which is …   Wikipedia

• YUV — Y UV is a color space typically used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowed reduced bandwidth for chrominance components, thereby typically enabling transmission errors… …   Wikipedia

• Knuth's up-arrow notation — In mathematics, Knuth s up arrow notation is a method of notation of very large integers introduced by Donald Knuth in 1976. It is closely related to the Ackermann function. The idea is based on iterated exponentiation in much the same way that… …   Wikipedia
