A 3D Wideband GBSM for THz Communications in Indoor Scenarios

In this paper, we propose a three-dimensional (3D) wideband reference regular-shaped geometry-based stochastic model (RS-GBSM) at terahertz (THz) bands for indoor scenarios. The corresponding sum-of-sinusoid (SoS) simulation model is established to verify the reference model. The proposed model combines a two-sphere model with a elliptic cylinder model, where the received signal is considered as a summation of the line-of-sight (LoS), single-bounce (SB), and double-bounce (DB) components. The von-Mises-Fisher (VMF) distribution is applied to the expressions of azimuth and elevation angles to depict the distribution of scatterers. Based on the proposed THz RS-GBSM, the power delay profile (PDP) and channel transfer function (CTF) are obtained. The delay spread and frequency correlation function (FCF) are investigated. The simulation results demonstrate the validity of the proposed model to describe indoor THz channels.
