Abstract:

The current program has two major thrusts i.e., the development and refinement of practical low-cost, robust, narrowband and variable-rate speech algorithms and voice terminal structures, and the establishment of an experimental wideband satellite network to serve as a unique facility for the realistic investigation of voicedata networking strategies. This report covers work in the following areas development of a custom-LSI-based narrowband channel vocoder studies and real-time implementation of improved vocoder structures and algorithms evaluation of speech processing capability of CCD- based spectrum analysis hardware preparation of hardware and firmware for an upcoming speech algorithm test and evaluation program design and implementation of packet voice terminals and local area access facilities progress in satellite network and internetted packet voice conferencing and in the development of new packet voice network protocols and design of a traffic emulation module for the wideband experimental network.
