Digital Channel Efficiency Model.

Abstract

This report describes the design, fabrication, and testing of a bit rate reduction system. The Digital Channel Efficiency Model (DCEM) effectively doubles the transmission bandwidth (number of channels) of digital communications systems, by providing an overall 2:1 compression of DCM signals, either DCS or NATO, transparent to any users, with no modifications of existing equipment. The DCEM also provides a variety of DCS-NATO interface modes at the digroup level. Originator supplied keywords include: Digital Transmission, Channel Compression, Bit Rate Reduction, and Digital Speech Interpolation.
