WebbShannon gave a lower bound in 1959 on the binary rate of spherical codes of given minimum Euclidean distance $\rho$. Using nonconstructive codes over a finite alphabet, we give a lower bound that is weaker but very close for small values of $\rho$.

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… Webb证明：.

WebbShannon’s information-theoretic lower bound has been developed for uniquely decodable systems of bit strings, while ordinary data structures often consist of many separate blocks of memory. One might expect that adapting the bound to data structures is trivial, but we demonstrate that this is not the case. Webb$\begingroup$ I wouldn't accept that number.
