Webb10 aug. 2013 · Jamie Vicary explained Shannon capacity to me last summer, using the same example of the 5-cycle C 5 C_5 and its ‘strong square’ C 5 ⊠ 2 C_5^{\boxtimes 2}. But he presented it in the form of a puzzle: find as many pairwise nonadjacent vertices as you can in C 5 ⊠ 2 C_5^{\boxtimes 2} .

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… Webb21 juli 2016 · Shannon-Hartley tells you that you can reduce data rate to get better range (in theory without limit).

Hartley's name is often associated with it, owing to Hartley's rule: counting the highest possible number of distinguishable values for a given amplitude A and precision ±Δ yields a similar expression C′ = log (1+A/Δ).

WebbMany practical obstacles stand in our way and we can rarely achieve Shannon’s capacity. We ﬁrst state the simplest case as theorized by Nyquist. In 1927, Nyquist developed a thesis that in order to reconstruct a signal from its samples, the analog signal must be sampled at least two times its highest frequency. From this comes the ideas that WebbIn texts that introduce the Shannon capacity, bandwidth W is often assumed to be the half-power frequency, which is closely related to MTF50. Strictly speaking, W log2(1+S/N) is …
