Abstract :
New upper bounds on the redundancy of Huffman codes are provided. A bound that for 2/9 \\leq P_{1} \\leq 0.4 is sharper than the bound of Gallager, when the probability of the most likely source letter P_{1} is the only known probability is presented. The improved bound is the tightest possible for 1/3 \\leq P_{1} \\leq 0.4 . Upper bounds are presented on the redundancy of Huffman codes when the extreme probabilities P_{1} and P_{N} are known.
