Map-based channel model for 5G wireless communications

This paper introduces a type of channel models especially suitable for demanding air interface evaluations like the case in many 5G communication systems will be. The map-based channel model is based on the digital information of the environment and uses a deterministic method to search for the propagation links. Most often used link calculation method is ray-tracing. Also here the examples are covered with ray-tracing. However, it is practically impossible to have all the environment information stated deterministically leading thus either to simplifications in the modelling or in the use of hybrid modelling methods. The hybrid modelling here means to add stochastic add-ons on top of the deterministic path search. The model evaluations are reflected to the corresponding geometry based stochastic channel model (GSCM).
