Cellular automata based encompression technology for voice date

This paper reports an efficient compression technology for voice data. It is developed around Programmable Cellular Automata (PCA) structure. The program executed on PCA is so designed that it ensures high speed transmission of voice data with desired level of security (encryption). Further, the regular and local neighborhood structure of CA is employed to design high speed low cost implementation of the encompression (encryption + compression) scheme. Comparison with standard GSM (Global System Mobile) technology, in respect of compression ratio, the quality of D'encompressed voice data and the quality of security attained, confirms high potential of the proposed scheme.
