... Based on the effective bandwidth theory, the joint in uence of the channel fading, the data outsourcing process, and the scheduling discipline in the QoS metrics are studied. We obtain a closed-form ... probabilistic delay constraint is defined as the pair (D t , ε), where D t is the target delay and ε is the probability of exceeding it. On the other hand, in...

In the following, we discuss the delay sources at the two layers and argue that, in both cases, a common underlying model of Gaussian delay uncertainty ... shown in Figure 1, there is an offset between the transmit time of the pulse at the sender and the arrivaltimeestimateatthereceiver.

... ambiguities in the CF envelope. Also, the relatively constant slope in the re- gion of 0.7–1 chips can be explained by the combination of high time-bin steps and the presence of the deep fades in the CF: ... ambiguities in the CF envelope sets an up- per bound on the step of searching the time-bin hypotheses (Δt) bin , in the sense that if the time-...
