APOS: Adaptive Parameters Optimization Scheme for Voice over IEEE 802.11g
—In this paper we present APOS, a method for dynamically adapting the parameters of IEEE 802.11g to the estimated system state, with the aim of enhancing the quality of a voice c...

Voice capacity under quality constraints for IEEE 802.11a based WLANs
The communication of voice over wireless local area networks (WLANs) is influenced by the choice of speech codec, packetization interval and PHY layer bit rates. These choices aï...

Speech-adaptive layered G.729 coder for loss concealments of real-time voice over IP
In this paper, we propose a speech-adaptive layered-coding (LC) scheme for the loss concealments of real-time CELPcoded speech transmitted over IP networks. Based on the ITU G.729...
