An information theoretic point of view to MIMO channel modelling

The tutorial presents an in-depth introduction to recent results on MIMO channel modelling. A unifying approach, based on the principle of Maximum Entropy, is provided to construct consistent models: the consistency argument is at the heart of scientific inference and gives an explicit answer to the problem posed by the striking number of papers dedicated to MIMO channel models´. Indeed, nearly all the models proposed are different and moreover validated by measurement campaigns! Who should we trust?
