Huffman Coding Huffman coding is the best known form of entropy coding The premise behind Huffman coding is that more frequently occurring symbols are coded using longer code words To accomplish this variable length code words are assigned to symbols based on their frequency of occurrence Huffman code satisfies two conditions 1 All code words are uniquely decodable 2 No delimiters or extra information is inserted in the code words to facilitate decidability The first condition is accomplished by the use of prefix code This leads to the second condition No markers are needed to separate the code words because of the use of prefix code Huffman coding have fastest adaptive version has See Answer
