In recent years the concept of the effective capacity that relates the physical layer characteristics of a


wireless channel to the data link layer has gained a lot of attraction in wireless networking research


community. The effective capacity is based on Grtner Ellis’ large deviation theorem and it is used to


provide the statistical QoS provisioning in the wireless networks. Effective capacity also helps in the


analysis of the resource allocation or scheduling policies in various wireless systems such as Relay


networks, multi-user systems and multi-carrier systems subject to statistical QoS requirements. The


effective capacity in noise limited wireless network has already been investigated in the recent works.


Considering the interference limited wireless channels,in this paper we propose an analytical approach


based on Laplace’s method for the effective capacity of uncorrelated Rayleigh fading channel in the


presence of uncorrelated Rayleigh fading interference. The accuracy of the analytical model for the


effective capacity is validated by numerical simulations. We also provide the evaluation of tail


probability of the delay and maximum sustainable rate. The validation results reveal that the proposed


mathematical approach to the effective capacity can open the path for further researches in statistical


QoS provisioning in interference limited wireless networks.
