Modeling the power angular profile of dense multipath components using multiple clusters

In this work, we will discuss the modeling of the Power Angular Profile (PAP) of the Dense Multipath Components (DMC), taking into account multiple angular clusters. We have extended the maximum likelihood estimation of the angular DMC parameters in the RiMAX framework, so that the PAP of the DMC can be modeled with a multimodal von Mises distribution. This allows us to better characterize the diffuse scattering between transmitter and receiver, originating from multiple reflections in an environment. We have validated our proposed method with synthetic radio channel data based on Monte Carlo simulations, and have shown the importance of applying a multimodal assumption over a unimodal one.
