摘要
提出了一种改进的四进制哈夫曼树的生成算法,通过分析算法的平均码长和编码效率,论证了算法相对于传统的四进制算法的优点。并用C语言分别实现两种算法,进行了压缩比和压缩时间的比较,证明了改进算法在压缩比和压缩速度上的提升。
This paper proposed an improved quaternary Huffman tree algorithm, demonstrated the advantages of improved qua- ternary algorithm by analyzing the average code length and coding efficiency compared to conventional quaternary algorithms. And implemented the two algorithms by C language ,made a comparison between the two algorithms in ratio and compression time, proved algorithm compression ratio and compression speed of the upgrade.
