The Capacity with Probabilistic Delay Constraint CDt,Ɛ expresses the maximum source rate that may be supported in a wireless system with a probability Ɛ of exceeding certain delay bound Dt. In , CDt,Ɛ was calculated for a Rayleigh channel carrying a constant rate flow. In this work, the potential of the effective bandwidth theory is shown by evaluating this constrained capacity for a variable rate source modeled as an ON-OFF process. Cross relations among ON-OFF process parameters, fading channel statistics, QoS constraints and maximum allowable mean source rate are displayed by the obtained closed-form expressions. CDt,Ɛ is measured in different scenarios to exhibit to which extent higher time-correlation of the channel response or longer ON-OFF periods are harmful to the delay behaviour, getting a lower value of the capacity CDt,Ɛ.
