Radio channel measurement and modelling techniques

Abstract

This chapter is dedicated to radio channel measurement and modelling techniques for beyond 4G networks, in particular: • new measurement techniques not only targeting radio channels, but also material properties in new frequency bands (Section 9.1), • improved physical models, cowering full-wave as well as ray-based methods, with a specific sub-section dealing with diffuse scattering (DS) and complex surfaces (Section 9.2), • progress in analytical models (Section 9.3), • new channel estimation tools for model development based on channel sounding data (Section 9.4), and • finally, updates on COST 2100 channel models, enabling to include new features such as massive and distributed multiple-input multiple-output (MIMO) aspects (Section 9.5).
