http://witestlab.poly.edu/blog/nyquist-formula-relating-data-rate-and-bandwidth/ 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…
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 This section focuses on the single-antenna, point-to-point scenario. For channel capacity in systems with multiple antennas, see the article on MIMO. Bandlimited AWGN channel If the average received power is 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 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 • Error exponent Visa mer Webb17 mars 2024 · Signal to noise ratio affects all wireless networks, and this includes Bluetooth, Wi-Fi, 4G, ...
