Huffman Based Code Generation Algorithms: Data Compression Perspectives

This article proposes two dynamic Huffman based code generation algorithms, namely Octanary and Hexanary algorithm, for data compression. Faster encoding and decoding process is very important in data compression area. We propose tribit-based (Octanary) and quadbit-based (Hexanary) algorithm and compare the performance with the existing widely used single bit (Binary) and recently introduced dibit (Quaternary) algorithms. The decoding algorithms for the proposed techniques have also been described. After assessing all the results, it is found that the Octanary and the Hexanary techniques perform better than the existing techniques in terms of encoding and decoding speed.
