Peter Smith is Professor of Statistics at the Victoria University of Wellington. His research interests include the statistical aspects of design, modelling and analysis for communication systems, information theory, stochastic processes and applied probability.

Large wireless communication networks are widely believed to offer “free” interference reduction. This has led to a huge growth of research in performance analysis of large systems, where many users communicate
with 100s of antennas located in a large array of antennas. Since wireless channels are often modelled as random Gaussian matrices, a considerable body of work now exists on the effect of large random matrices in performance analysis. The process where large numbers of antennas automatically removes interference is called favourable propagation and is a property of large random vectors. However, in contrast to the statistical Gaussian channel models, more fundamental channel models are also of interest based on physical ray-tracing. In this talk I demonstrate that the two types of models lead to very different conclusions. In order to do this, the asymptotic interference variable is analysed as the numbers of antennas and users in the system grows to infinity.
