Abstract

This scheme will compress a file/data used for transmission. This is similar to coding the data. Transmit the compressed file. On the receiving end, decompress the file/data. This is similar to decoding the data. For this file/data transfer scheme, the following steps are required: ~ First prepare a file which contains common data. This file contains base tables. The base table becomes an index table for subsequent transmissions of files or data. This file, which consists of base tables, is called the master file. (Image Omitted) ~ Transmit the master file once. ~ Then prepare the base table file which has an index into base table numbers of the master file. In the base table file, the ordering of base table numbers is random.
