Competitive Advantage of Huffman and Shannon-Fano Codes

open access: yes
For any finite discrete source, the competitive advantage of prefix code $C_1$ over prefix code $C_2$ is the probability $C_1$ produces a shorter codeword than $C_2$, minus the probability $C_2$ produces a shorter codeword than $C_1$.

Maximal codeword lengths in Huffman codes

open access: yes, 1992
The following question about Huffman coding, which is an important technique for compressing data from a discrete source, is considered. If p is the smallest source probability, how long, in terms of p, can the longest Huffman codeword be?

158 LETTER Huffman-Based Test Response Coding

open access: yes, 2005
SUMMARY Test compression / decompression is an efficient method for reducing the test application cost. In this letter we propose a response compression method based on Huffman coding. The proposed method guarantees zero-aliasing and it is independent of
