This document explores the Lempel-Ziv data compression algorithm, focusing on a specific example utilizing a structured dictionary format. It illustrates the steps taken in compressing a sequence of symbols, applying the algorithm in a progressive manner. Key aspects include the creation of addresses and entries in the dictionary, which enhances the compression efficiency for transmitting data. By breaking down how the algorithm works, this example serves as a practical guide for understanding and implementing Lempel-Ziv compression in data transmission scenarios.
