| Abstract: |
| Based on the analysis of LZ77 compression algorithm,the effect of the error input codeword on decoder and reconstructed data is discussed.Then the error propagation is researched.It is clear that the work is greatly useful to recover LZ compression process from error propagation and ensure data integrity. |
| Key words: Adaptive dictionary,LZ algorithm,Data compression,Error propagation, |
