Abstract
Unique Huffman codes are generated with each being associated with a symbol. The unique codes are grouped according to a property of the unique codes such as length. The segments of a data stream to be decoded are compared with the grouped unique codes. Each segment has the same property as the grouped unique codes being compared with.
