Abstract:

This report describes the design and construction of prototype portable voice communication units and the implementation of the BBN robust 16 kbits adaptive predictive coding algorithm as a full-duplex real-time speech coder on these units. The report documents the hardware and software design and implementation efforts, and presents the results of a hardware production cost study. Work on algorithm simplification of the BBN 2.4 kbits harmonic deviations LPC speech coder is also described. Author
