摘要
一般情况下,哈夫曼编码所采用的存储结构及构树方法,不仅影响编码效率,而且也没充分利用存储空间.本文改顺序存储为链式存储,对叶结点和非叶结点采用不同的存储结构来降低空间复杂度.在编码时,充分利用短码字且基于树型模式匹配进行编码,提高了编码性能和传输效率.
Generally, the storage of Huffman coding and the way of creating Huffman tree,which not only influence the coding efficiency, but also do not fully make use of the storage space. In this paper, sequential storage is changed into chain storage for reducing the space complexity, and two different storage structures are applied to store leaf node and non-leaf node. Also, in order to improve the efficiency of coding and transmitting, short coded keys and the tree pattern matching have been fully applied to the Huffman coding.
