Abstract
The audio quality provided by some simple FEC schemes is studied. We deal with an M/M/l/K queueing model and assume that some of packets are lost due to noise or interference in the transmission as well as buffer overflow in the router. We consider the following two schemes: One is the Fixed/Variable Scheme that fixes the volume of original data and varies the volume of redundant data in a packet, and the other is Variable/Fixed Scheme that varies the volume of original data and fixed the volume of the whole data. We showed the cases where the Fixed/Variable Scheme improves the audio quality of the system.
