Abstract :
To alleviate congestion at thin route multiplexers such as are used in VSAT systems, some transmitters are forced to drop speech packets. Receiver reconstruction of the lost speech invariably produces some degradation of quality. The authors exploit the knowledge of dropped packets at the transmitter to mitigate this degradation
