每个长为l的码都可以在后面补上n−l位（n为码的最大长度），且所有补完的结果不重复，所以∑irn...
State the Kraft inequality and its impact on instantaneous codes. 11. Gain insight into the Shannon’s source coding theorem. 12. Determine how extension codes can be implemented. 13. Outline the entropy (probability-based) and universal (adaptive) coding techniques. 14. Provide a step-by-step...
Kraft points (Kraft's inequality or Kraft-Levenshtein theorem) refer to a concept in information theory. It is a condition that must be satisfied for the existence of a prefix code. A prefix code is a code in which no codeword is a prefixof any other codeword. In other words, it is...
The paper will therefore study the equality cases of this theorem and demonstrate that these equality cases have similar results to that of the Kraft Inequality, although it is necessary to prove them in a different way since the latter theorem's proof is less direct....
The next theorem gives a version of the Kraft–McMillan inequality for codes in matrix monoids. Theorem 1 Let M={Mi|i∈I}⊆Tri(k,Z). If M is a code then ρ(M)>0 for all ⁎M∈M⁎ and(1)π(M)=∑i∈Iρ(Mi)−12k(k−1)≤1. The following theorem is a direct conseq...
