ABSTRACT:
A data compression scheme implemented based on V.42bis implemented in hardware within mobile units of a cellular system is disclosed. The data compression scheme includes a number of hardware state machines that perform data compression and decompression functions. Additionally, a dictionary of codewords and character strings is organized according to keys and is implemented as a balanced binary tree.
