摘要
Terahertz (THz) communications systems have been considered as one of the enabling technologies for beyond 5G mobile networks, with the ability to offer higher capacity and lower latency compared to the current systems. In this paper, we develop a new THz channel model that captures rough surface scattering while considering attenuation due to molecular absorption of the atmosphere. The main advantage of the proposed model is that it conserves the energy of the channel impulse response, regardless of the number of launched rays in the ray-tracing simulator, or the size of the tiles for the scattering surface. Using the proposed model, a simple propagation scenario for the indoor environment has been analyzed, and the improvement over other models discussed in detail.
