Compression of Chinese text files using a multiple four-bit coding scheme
Ghim Hwee Ong, Shell Ying Huang · 1992
This paper reports on the results of the study of a two-pass reversible data compression scheme. The restricted variable length coding method using multiples of 4-bit code values is simple in concept and easy to implement. The compression results and the compression/decompression times regarding four large Chinese text files are superior to those using character-based two-pass Huffman coding and adaptive Huffman coding methods. The compression results are comparable with what the LZW method achieves, and the compression/decompression process it slightly faster.>
