Abstract

A method of alpha compression is derived from seven different data types which when combined pro- duce excellent text compression for many different lan- guages.

This text was extracted from a PDF file.
At least one non-text object (such as an image or picture) has been suppressed.
This is the abbreviated version, containing approximately 81% of the total text.

TEXT OVER THE AIR COMPRESSION TECHNIQUE

by Karl R. Weiss

  A method of alpha compression is derived from seven different data types which when combined pro- duce excellent text compression for many different lan- guages.

l Backspace one character position and insert a period followed by a blank space.

l Backspace one character position and insert a comma followed by a blank space.

  The basic format of the algorithm is to send sym- bols or tokens of one byte. When a byte or token is in the range of 0 to 7F Hex then this token is extended to include the next byte in which this token will consist of two bytes which have 32768 different entries. The one byte token map is made up of the following entries:

ONE BYTE TOKEN MAP

1.26 small letters: a - z
2. 26 capital letters: A - Z
3. 10 digits: 0 9
4.18 punctuation
5.14 for special commands
6.36 for most commonly used words

The special commands are formulae to help format sentences efficiently. Examples of such commands are:

  Most commonly used words are a list of words that are frequently used in the language being supported with the addition of a blank space at the end.

  The two byte token map is a list of the 32728 most commonly used words that are frequently used in the language that is being supported other than the ones defined in the one byte section listed above. A blank space may be added to the end of the words, as this will tend to improve the efficiency of the compression. For each...
