Binary erasure channel — A binary erasure channel (or BEC) is a common communications channel model used in coding theory and information theory. In this model, a transmitter sends a bit (a zero or a one), and the receiver either receives the bit or it receives a message … Wikipedia
Binary erasure channel — Der Begriff binärer Auslöschungskanal (kurz BEC von engl. binary erasure channel) wurde in der Informationstheorie erstmals von Peter Elias verwendet. Man bezeichnet damit einen gedächnisfreien informationstheoretischen Kanal, der ein Bit (0 oder … Deutsch Wikipedia
Binary symmetric channel — A binary symmetric channel (or BSC) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver receives a bit. It is assumed that… … Wikipedia
Channel (communications) — Old telephone wires are a challenging communications channel for modern digital communications. In telecommunications and computer networking, a communication channel, or channel, refers either to a physical transmission medium such as a wire, or … Wikipedia
Erasure code — In information theory, an erasure code is a forward error correction (FEC) code for the binary erasure channel, which transforms a message of k symbols into a longer message (code word) with n symbols such that the original message can be… … Wikipedia
erasure code — noun A forward error correction (FEC) code for the binary erasure channel, which transforms a message of k symbols into a longer message with n symbols such that the original message can be recovered from a subset of the n symbols … Wiktionary
Information theory — Not to be confused with Information science. Information theory is a branch of applied mathematics and electrical engineering involving the quantification of information. Information theory was developed by Claude E. Shannon to find fundamental… … 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
