Deterministic Approach of Indoor Room THz Multipath Channel Model

Abstract

The terahertz (THz) communications are predicted to be the next generation of wireless communication networks for the coming 5–10 years. Both the transmitter (TX) and receiver (RX) employ highly directive antennas to overcome the problem of high propagation as well as reflection losses in THz band frequencies. One of the primary objectives of this paper is to investigate the influence of multipath channels on transmission links in an indoor office environment with the raytracing technique for line-of-sight (LoS) scenario. Furthermore, it elaborates the angle of arrival (AoA) and angle of departure (AoD) considering the relative received power, angular power profile (APP), and time of arrival (ToA). The LoS path is at 230.2° in azimuth plane with angular power of -92.36 dB.
