Webb2 dec. 2024 · In the context of noisy channel coding, a theorem by Shannon says that, by using suitable channel codes, communication with rate up to the channel capacity is possible. WebbIn information theory, the noisy-channel coding theorem establishes that however contaminated with noise interference a communication channel may be, it is possible to …

WebbThis surprising result, sometimes called the fundamental theorem of information theory, or just Shannon's theorem, was first presented by Claude Shannon in 1948. The Shannon limit or Shannon capacity of a communications channel is the theoretical maximum information transfer rate of the channel, for a particular noise level. WebbIn information theory, the noisy-channel coding theorem (sometimes Shannon's theorem or Shannon's limit), establishes that for any given degree of noise contamination of a … devonshire mark master masons
