Identification of radiowave propagation modes in urban microcell environments

Conventional semi-empirical or stochastic propagation prediction models are insufficient for the planning of 4G wireless communication systems. These systems suffer from time dispersion and angular dispersion of the multipath radio channel. Instead deterministic prediction models become more interesting to predict the propagation channels for 4G networks. The ray tracing (RT) model is one of the popular deterministic models nowadays. The accuracy of deterministic channel modeling is the object of debate. In order to do a detailed comparison of RT-predictions with 3D channel sounder measurements, the different radiowave propagation modes are identified by template matching of the 3D measurements with RT-simulations as template
