Kraftdistribution
Kraftdistribution is not a widely standardized term in information theory, but it is sometimes used informally to describe a probability distribution that is derived from the codeword lengths of a prefix code and that respects Kraft’s inequality. In this sense, a kraftdistribution is the distribution over codewords implied by a given length function l(w) for a prefix code.
If a binary prefix code has codeword lengths l(w) for each word w in its codebook, Kraft’s
This distribution is not unique: different prefix codes (with different sets of lengths) induce different kraftdistributions.
In practice, one might refer to “the distribution induced by a prefix code” rather than using the
