Huffman Codes Lecturer : Michel
Shannon’s noiseless coding theorem tells us how compactly we can compress messages in which all letters are drawn independently from an alphabet A and we are given the probability pa of each letter a ∈ A appearing in the message. Shannon’s theorem says that, for random messages with n letters, the expected number of bits we need to transmit is at least nH(p) = −n ∑ a∈A pa log2 pa bits, and ther...
متن کاملEntropy and Huffman Codes
We will show that • the entropy for a random variable gives a lower bound on the number of bits needed per character for a binary coding • Huffman codes are optimal in the average number of bits used per character among binary codes • the average bits per character used by Huffman codes is close to the entropy of the underlying random variable • one can get arbitrarily close to the entropy of a...
متن کاملDiscovery of Huffman codes
Large networks of IBM computers use it. So do high-definition television, modems and a popular electronic device that takes the brain work out of programming a videocassette recorder. All these digital wonders rely on the results of a 40-year-old term paper by a modest Massachusetts Institute of Technology graduate student—a data compression scheme known as Huffman encoding. In 1951 David A. Hu...
متن کاملAn efficient decoding technique for Huffman codes
We present a new data structure for Huffman coding in which in addition to sending symbols in order of their appearance in the Huffman tree one needs to send codes of all circular leaf nodes (nodes with two adjacent external nodes), the number of which is always bounded above by half the number of symbols. We decode the text by using the memory efficient data structure proposed by Chen et al. [...
متن کاملExistence of optimal prefix codes for infinite source alphabets
It is proven that for every random variable with a countably infinite set of outcomes and finite entropy there exists an optimal prefix code which can be constructed from Huffman codes for truncated versions of the random variable, and that the average lengths of any sequence of Huffman codes for the truncated versions converge to that of the optimal code. Also, it is shown that every optimal i...
