Variable-to-fixed length codes are better than fixed-to-variable length codes for Markov sources
-It is demonstrated that for finite-alphabet, Kth order ergodic Markov Sources (i.e., memory of K letters), a variable-to-fixed code is better than the best fixed-to-variable code (Huffman code). It is shown how to construct a variable-to-fixed length code for a Kth order ergodic Markov source, which compresses more effectively than the best fixed-to-variable code (Huffman code).

متن کاملOn the Analysis of Variable-to-Variable Length Codes
We use the \conservation of entropy" 1] to derive a simple formula for the redundancy of a large class of variable-to-variable length codes on discrete, memoryless sources. We obtain new asymptotic upper bounds on the redundancy of the \Tunstall-Huuman" code and the \Tunstall-Shannon-Fano" code. For some sources we provide the best existing upper bound for the smallest achievable asymptotic red...
متن کاملA Comparative Complexity Study of Fixed-to-variable Length and Variable-to-fixed Length Source Codes
In this paper we present an analysis of the storage complexity of Huffman codes, Tunstall codes and arithmetic codes in various implementations and relate this to the achieved redundancies. It turns out that there exist efficient implementations of both Huffman and Tunstall codes and that their approximations result in arithmetic codes. Although not optimal, the arithmetic codes still have a be...
