Reduction of Sufficient Number of Code Tables of -Bit Delay Decodable Codes

Kengo Hashimoto, Ken-ichi Iwata

A -bit delay decodable code-tuple is a lossless source code that can achieve a smaller average codeword length than Huffman codes by using a finite number of code tables and all…

The Optimality of AIFV Codes in the Class of -bit Delay Decodable Codes

Kengo Hashimoto, Ken-ichi Iwata

AIFV (almost instantaneous fixed-to-variable length) codes are noiseless source codes that can attain a shorter average codeword length than Huffman codes by allowing a time-varian…

Properties of k-bit Delay Decodable Codes

Kengo Hashimoto, Ken-ichi Iwata

The class of k-bit delay decodable codes, source codes allowing decoding delay of at most k bits for k >= 0, can attain a shorter average codeword length than Huffman codes. This p…

Optimality of Huffman Code in the Class of 1-bit Delay Decodable Codes

Kengo Hashimoto, Ken-ichi Iwata

For a given independent and identically distributed (i.i.d.) source, Huffman code achieves the optimal average codeword length in the class of instantaneous code with a single code…

Proceedings of the 11th Asia-Europe Workshop on Concepts in Information Theory

A. J. Han Vinck, Kees A. Schouhamer Immink, Tadashi Wadayama +24

This year, 2019 we celebrate 30 years of our friendship between Asian and European scientists at the AEW11 in Rotterdam, the Netherlands. Many of the 1989 participants are also pre…
