Satellite-to-indoor channel model for mobile receivers

Realistic channel models are prerequisites to develop advanced receiver positioning algorithms able to cope with the effects of signal propagation such as shadowing and multipath. In this contribution, we propose a novel and accurate wideband satellite-to-indoor channel model applicable to testing and validating range estimation algorithms for positioning applications. The advantage of the channel model compared to the state of the art is the ability to reproduce the spatial characteristics of multipath propagation seen by a moving receiver. To model satellite-to-indoor propagation, a combination of physical-deterministic mechanisms and stochastic methods is used. In this context, components occurring due to diffraction and transmission by walls, windows and doors are treated using physical-deterministic near field methods. For paths occurring due to indoor multipath propagation, a hybrid approach is used combining physical-deterministic and stochastic methods.
