Voice over wireless LAN: a fine-scalable channel-adaptive speech coding scheme

Abstract

Achieving a fine-scalable and channel-adaptive speech coding scheme to provide reliable voice communication in wireless IP networks is an important challenge that opens new directions for research. In this proposal we review the problems and issues in supporting voice over wireless networks and examine the role of new speech coding techniques and the proper use of existing network protocols aimed at providing adequate quality of service in this difficult environment. We propose a new coding scheme, that fulfills the requirements of robust and reliable VoWLAN expectantly.
