Improving Data Compression Ratio by the Use of Optimality of LZW & Adaptive Huffman Algorithm (OLZWH)

Abstract

There are several data compression Techniques available which are used for Efficient transmission and storage of the data With less memory space. In this paper, we have Proposed a two stage data compression Algorithm that is OLZWH which uses the Optimality of Lempel-Ziv-Welch (OLZW) and Adaptive Huffman Coding. With this proposed Algorithm, the data Compression ratios are Compared with existing Compression Algorithm for different data sizes. KEYWORS Optimality of Lempel-Ziv-Welch (OLZW), Adaptive Huffman coding, Compression Ratio.
