Deterministic diffraction loss modelling for novel broadband communication in rural environments

Abstract

This paper presents a deterministic modelling approach to predict diffraction loss for an innovative Multi-UserSingle-Antenna (MUSA) MIMO technology, proposed for rural Australian environments. In order to calculate diffraction loss, six receivers have been considered around an access point in a selected rural environment. Generated terrain profiles for six receivers are presented in this paper. Simulation results using classical diffraction models and diffraction theory are also presented by accounting the rural Australian terrain data. Results show that in an area of 900 m by 900 m surrounding the receivers, path loss due to diffraction can range between 5 dB and 35 dB. Diffraction loss maps can contribute to determine the optimal location for receivers of MUSA-MIMO systems in rural areas.

“…Also, the current model only considers clear line-of-sight path cases. A further development taking into account the diffraction [10] is needed in order to extend the applicability of the model.…”
