Abstract

The contribution of this paper is in applying parameter replacement techniques to speech that is compressed by the Federal Standard 1016 CELP speech coder, protected by Reed–Solomon codes, and transmitted over a wireless channel. The parameter replacement results in significant improvement in speech quality without any increase in bit rate.
