Complexity-aware adaptive jitter buffer with time-scaling

In VoIP applications, packet loss, delay and delay jitter are inevitable and have a large impact on the perceived speech quality. Jitter buffers are commonly deployed to compensate for jitter in order to play out the received packets continuously. For mobile devices, due to limited battery power, computational complexity has to be kept to a minimum. In this paper, we propose a jitter buffer management which takes complexity into consideration. The algorithm adaptively adjusts the play-out delay under certain complexity constraints. Simulation results show that our proposed algorithm can keep complexity under specified constraints while still optimizing jitter induced packet losses and average delay.
