Title
A Hybrid Media Transmission Scheme for Wireless VoIP
Abstract
In this paper, we propose an optimization framework for real-time voice transmission over wireless tandem channels prone to both bit errors and packet erasures. Utilizing a hybrid media dependent and media independent error correction scheme, our proposed framework is capable of protecting voice packets against both types of errors. For each group of frames associated with one speech spurt, the framework finds the optimal parity assignment of each voice frame according to its perceptual importance such that the quality of the received group of frames is maximized. Our performance evaluation results show that the proposed scheme outperforms a number of alternative schemes and has a low computational complexity.
