单词	Kraft’s inequality
释义	Kraft’s inequality Computer When an instantaneously decodable code is to be formed from an alphabet of q letters, with the ith codeword being λ‎_i letters in length, Kraft’s inequality $\sum_{i = 1}^{n} q^{- λi} ⩽ 1$ is a necessary and sufficient condition for such a code to be constructible with n codewords. In a code with no codewords remaining for allocation, the equality sign operates. See also prefix codes.
