WebbThe theorem establishes Shannon's channel capacity for such a communication link, a bound on the maximum amount of error-free digital data (that is, information) that can be transmitted with a specified bandwidth in the presence of the noise interference, assuming that the signal power is bounded, and that the Gaussian noise process is … Webb87K views 6 years ago Everything Long before wireless devices became ubiquitous, a brilliant mathematician named Claude Shannon had already determined one of the fundamental limits they would...
WebbThen Shannon coding has lengths $(2,2,6,6,6,\ldots,6)$ while Fano coding splits between 0.4 and 0.26 and then for the 0.6 probability on the right it splits between the second and third 0.02. Continuing on we see that 0.26 is encoded with a length of 3, larger than Shannon length.
