Abstract :
In the end-to-end voice communication networks, the packet losses caused by network congestion and wireless channel errors reduce the efficiency of the forward error correction (FEC) scheme. Especially for mobile VoIP, network congestion and wireless channel status changed very fast. This paper presents an adaptive FEC that can adaptive adjust and predict the FEC block according to the network status.
