A ray optical wave propagation model for the prediction in time variant scenarios

With the growing demand for wireless communication systems, wireless concepts for the data exchange in time variant scenarios in indoor and urban domains become more and more interesting. In order to describe and thus assess the mobile radio channels in such scenarios, simulations are required. The main aspect is the time-variance of the channel impulse response. This paper discusses the demands for models to describe the radio channel in time variant environments and presents an appropriate ray tracing approach. The performance of the ray tracing algorithm is demonstrated by a comparison from predictions to several measurement campaigns.
