Shannon information capacity
Information theory, developed by Claude E. Shannon in 1948, defines the notion of channel capacity and provides a mathematical model by which it may be computed. The key result states that the capacity of the channel, as defined above, is given by the maximum of the mutual information between the input and … Visa mer Channel capacity, in electrical engineering, computer science, and information theory, is the tight upper bound on the rate at which information can be reliably transmitted over a communication channel. Visa mer The basic mathematical model for a communication system is the following: where: • $${\displaystyle W}$$ is the message to be transmitted; • $${\displaystyle X}$$ is the channel input symbol ( Visa mer An application of the channel capacity concept to an additive white Gaussian noise (AWGN) channel with B Hz bandwidth and signal-to-noise ratio S/N is the Shannon–Hartley theorem Visa mer • Bandwidth (computing) • Bandwidth (signal processing) • Bit rate Visa mer If G is an undirected graph, it can be used to define a communications channel in which the symbols are the graph vertices, and two codewords may be confused with each other if their … Visa mer The noisy-channel coding theorem states that for any error probability ε > 0 and for any transmission rate R less than the channel capacity C, there is an encoding and decoding … Visa mer This section focuses on the single-antenna, point-to-point scenario. For channel capacity in systems with multiple antennas, see the … Visa mer WebbIn electronic communication channels the Shannon capacity is the maximum amount of information that can pass through a channel without error, i.e., it is a measure of its “goodness.” The actual amount of information depends on the code— how information is represented. But coding is not relevant to digital photography.
