Dependency Modelling in Wireless Networks


Stochastic models of wireless fading channels, arrival processes, and mobility build the basis for the solid wireless system design. The impact of spectral, temporal, and spatial correlation on the achievable performance of single- and multi-user networks is well researched. The models in literature are mostly limited to linear dependencies and positive correlation. In this talk, we propose general dependency models based on copula theory which include both positive and negative dependencies. First, we motivate the models from practical observations in frequency selective and multiple antenna channels. Second, the performance range for outage capacities is completely characterized. Third, for modern ultra-high reliable wireless systems, the zero-outage capacity is considered and the dependency structures in peaceful and wiretapped channels, which achieve positive zero-outage capacities, are derived. Finally, the talk closes with conjectures and open questions for future works.
