Command and Control Related Computer Technology. Part I. Packet Radio. Part II. Speech Compression and Evaluation

Abstract

This document describes progress on (1) the development of a packet radio network, and (2) speech compression and evaluation. Activities reported under (1) includes work on Station Software and Internetworking Research and Development; under (2) comparative informal evaluation of our perceptual-model- based variable frame rate scheme for transmitting LPC data with two other schemes under a number of vocoder conditions; development and testing of a new scheme for variable rate transmission of LPC gain parameter; and completion of the initial analysis of our recent factorial subjective speech quality study.
