Abstract
In this paper a new data compression technique has been proposed based on Lampel Ziv Welch (LZW) coding and block sorting. At first block sorting is performed on input data to produce permuted data. LZW coding is then applied on that permuted data to produce more compressed output. Though block sorting takes some extra time (the amount is very negligible), it increases the performance of LWZ compression much. The proposed model is compared with respect to LZW compression.
