Project: A generic radio channel model for propagation in inhomogeneous forests at 40 GHz

Main Objective:
This proposal aims to take forward the RET modelling work carried out by the Principal Investigator (PI) under a UK consortium, which identified a number of problems in the estimation and establishment of the input parameters required by the RET model. In addition, this research intends to investigate current approaches and develop new
more accurate narrow and wideband channel models through theoretical investigations as well as experimental data gathering at 40 GHz in view of BFWA applications. The influence of inhomogeneous vegetation in a cluttered environment with respect to their influence and the radio propagation path as well as their potential origin of interference within networks and onto other networks will be addressed in this program. Both narrow and wideband channel performances and fast fading dynamics of signals propagating through, around or scattered from vegetation will be modelled and included in the prediction tool, as these are critical for quality of service, RF regulation and the assessment of spectrum efficiency.
