Evaluation of MIMO capacity in regular chaflane street corners for microcellular communications

In this paper, a ray launching model based on the application of the uniform theory of diffraction (UTD) and geometrical optics (GO) has been implemented for modelling the propagation in MIMO microcellular urban scenarios. This model has been used to analyse the behaviour of the capacity in two street corners environments: Regular and chaflane street corners. The study of the environment of the two corners shows that there exist important differences between both street scenarios: capacity is higher in chaflane street corners. Finally the impact of the orientation of the transmitter and receiver is studied in terms of capacity.
