| 摘 要： | 针对目前ＰＣ机文本文件通信中编码（ＡＳＣＩＩ）冗余度较大的情况，本文提出了１种利用变长码编码的自适应数据压缩算法．这种方法充分利用文件的局部冗余度，根据字符出现频率的变化，实时地调整编码表，以获得较高的压缩比．

| Abstract: | There are higher redundancy in computer communication code (ASICC) of test and file. Faeing such a situation,a new approaeh of adaptive clata compression is presented. This approach alter real - time code table, according to yaring of character frequency. Higher compression rate can be acquined. Algorithms is diseribed carefully and the experimental result is satisfactory. |

| Keywords: | compression rate variable length code code graduation real - time |
