Abstract

Over the air compression of text information is usually accomplished by choosing tokens which represent the most commonly used phrases, words, or parts of words. The smallest size tokens (in num- ber of bits) are assigned to those phrases, words, or parts of words which occur most often in the domain for which the text compression is being used and defined. This leads to tokens which have differ- ent sizes and which are not integer multiples of each other. Therefore the start location of token bound- aries is not known up front by the receiving decom- pression routine and is a function of previous received tokens. This is unlike using standard ASCII 7 bit values where the token boundary occurs every 7 bits.
