| Abstract: | Based on the analysis of the LZW method,the deficiencies of LZW method are discussed.It has improved the method,substantially reduce the length of the code and the effects of the dereferencing changes about the matching length,embraced the LZW method completely and increased the average rate.Further,the improved method is analyzed. |
