SATT Systems S.A., Brussels, Belgium

In this paper, we present the voice coding techniques that are proposed for the new Mobile Satellite Business Network (or MSBN) system. The paper describes not only some coding techniques that may be applied, but also the considerations that lead to them, hi the paper, we give a brief of the MSBN system, and its requirements for the voice coding sub-system. The choice of an MBE based vocoder is then discussed. Last, two key techniques that are involved in this implementation are presented: the LPC + correction representation of the spectrum envelope, and the Vector Quantisation technique that is used for transmission of the Linear Prediction parameters.
