WebbWhile Shannon entropies are not integer-valued and hence cannot be the lengths of code words, the integers fdlog D 1 p(x) eg x2X satisfy the Kraft-McMillan Inequality and hence there exists some uniquely decodable code Cfor which H p(x) E[l(x)]
WebbThe average codeword length for this code is l= 0.4 × 1 + 0.2 × 2 + 0.2 × 3 + 0.1 × 4 + 0.1 × 4 = 2.2 bits/symbol. The entropy is around 2.13. Thus, the redundancy is around 0.07 bits/symbol. 5/31 Minimum Variance Huffman Codes green and blue knitted sweaterWebb5.
