WebHuffman Encoding and Decoding Create unique symbols, and assign probabilities of occurrence to them. Determine minimum number of bits required for binary representation of the symbols. symbols = 1:6; p = [.5 .125 .125 .125 .0625 .0625]; bps = ceil (log2 (max (symbols))); % Bits per symbol Web4 dec. 2015 · Sorted by: 9. In a gist LZW is about frequency of repetitions and Huffman is about frequency of single byte occurrence. Take the string 123123123. (The following is an oversimplification but will make the point) LZW will identify that 123 is repeated three times and essentially create a dictionary of codes for sequences.
