Shannon’s Noisy-Channel Coding Theorem - Centrum Wiskunde

In information theory, Shannon's source coding theorem (or noiseless coding theorem) establishes the limits to possible data compression, and the operational meaning of the Shannon entropy. Named after Claude Shannon, the source coding theorem shows that (in the limit, as the length of a stream of … Visa mer Source coding is a mapping from (a sequence of) symbols from an information source to a sequence of alphabet symbols (usually bits) such that the source symbols can be exactly recovered from the binary bits … Visa mer • Channel coding • Noisy-channel coding theorem • Error exponent Visa mer Given X is an i.i.d. source, its time series X1, ..., Xn is i.i.d. with entropy H(X) in the discrete-valued case and differential entropy in … Visa mer Fixed Rate lossless source coding for discrete time non-stationary independent sources Define typical set A n as: Then, for given δ > 0, for n large enough, Pr(A n) > 1 − δ.
