Development of measurement-based ray tracer for multi-link double directional propagation parameters

This paper introduces a new method for combining high resolution parameter estimates with ray-launching based wave propagation prediction. The idea behind the proposed measurement-based ray tracing tool is to use measured data as the input for a ray-launching algorithm. With the developed tool, it is possible to identify dominant propagation phenomena and relate them with the objects in the physical environment. A core function of the tool is the identification of the scattering points of the multipath components by utilizing the measured multi-link double directional parameter estimates. The obtained knowledge is essential in developing a multi-link MIMO channel model.
