During the late 1920s, Harry Nyquist and Ralph Hartley developed a handful of fundamental ideas related to the transmission of information, particularly in the context of the telegraph as a communications system. At the time, these concepts were powerful breakthroughs individually, but they were not part of a comprehensive theory. In the 1940s, Claude Shannon developed the concept of channel capacity, based in part on the ideas of Nyquist and Hartley, and then formula… Webb16 juli 2024 · The Shannon noisy channel coding theorem states that the reliable discrete-time rate r (whose unit is bits per symbol, or bits per channel-use, or bpcu) is upper-bounded (1) r < 1 2 log 2 ( 1 + S N) where S and N are the discrete-time symbol energy and noise energy respectively.

The directed information was coined by James Massey in 1990, who showed that its an upper bound on feedback capacity. For memoryless channels, Shannon showed that feedback does not increase the capacity, ... 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: 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 scheme transmitting data at rate R whose error probability is less than ε, for a sufficiently … Visa mer • Bandwidth (computing) • Bandwidth (signal processing) • Bit rate • Code 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 An application of the channel capacity concept to an additive white Gaussian noise (AWGN) channel with B Hz bandwidth and Visa mer This section focuses on the single-antenna, point-to-point scenario.
