Satellite on-board processing of packetized voice

Spectral room on satellite up-links is becoming more precious as time progresses, especially in the UHF band. By using packetized voice, more spectral efficiency can be achieved. Voice is a delay-sensitive type of traffic. This paper examines the tradeoffs between spectral advantages of packetized voice with other data traffic and extra processing delay caused by packetization. Specifically, relations between voice throughput and end-to-end delay in a processing satellite are developed.
