Application of reduced rate coding and speech interpolation to the DCS
The authors provide engineering criteria for the application of reduced-rate coding (RRC) and speech-interpolation (SI) techniques to the defense communications system (DCS). These two technologies each offer a 2:1 compression of bit rate or bandwidth for transmission of voice channels. Compression via speech interpolation is achieved through the removal of the gaps and pauses which occur naturally in speech, while reduced-rate coding uses 32 kb/s coding instead of conventional 64 kb/s coding. A description of the performance in these two technologies is given and the application criteria for RRC/SI use in the DCS are developed.<>
