Webb19 jan. 2010 · But Shannon’s proof held out the tantalizing possibility that, since capacity-approaching codes must exist, there might be a more efficient way to find them. The quest for such a code lasted until the 1990s. But that’s only because the best-performing code that we now know of, which was invented at MIT, was ignored for more than 30 years. Webbconcerning whether the Shannon limit can be broken or not. In particular, we argue that a new way of defining channel capacity taking account of all admissible sets of distributions seems reasonable, and we show that the corresponding channel capacity is unfortunately the same as the Shannon limit for channels carrying a finite number of symbols.
