摘要：In this paper we discuss and compare methods to analyse the influence inter-cell interference will have oncoverage/outage probabilities in cellular networks. The framework is based on a common method to findthe Laplace transform of the distribution of interference from neighbouring cells. It turns out that forSuzuki distributed fading the analysis is highly simplified. In case of Rayleigh faded channels only, theanalysis is even more simplified. The modelling approach, which is based on classical probab ility methods,rather than on modern measure theory for point processes, allows for both fixed and stochastic locations ofbase stations. The different models are applied to quantify the effect of inter -cell interference oncoverage/outage probabilities and on spectrum efficiencies in LTE networks. We consider severalscenarios ranging from fixed hexagonal layout of base station to stochastic location of based on uniformdistribution of base stations. We also extend the coverage/outage analysis for the Gin ibre Point Process toSuzuki faded environment. Numerical examples show large differences in both spectrum efficiency andcoverage/outage probabilities for the different network scenarios considered.
