Abstract

The eventual practical deployment of a terahertz (THz) wireless communication system requires a proper channel model. By considering the unique characteristics of THz propagation, this paper proposes a geometric-statistic channel model for system-level simulation. This work also provides an evaluation methodology for investigating the system performance. Numerical results reveal that the proposed channel model is not only suitable to describe the physical characteristics of the THz channel, but also to investigate system-level performance.

Notes

  1. The influence of double-reflected paths might not be negligible as interference. This paper, however, does not consider their influence with a high signal-to-interference-plus-noise ratio (SINR) assumption.

  2. This paper uses ‘path’ and ‘cluster’ interchangeably.

  3. This notation for angular measurements is used for the rest of whole paper because it makes the angular analysis easier and it also gives an intuitive interpretation at the measurement point.

  4. Refs. [11] and [12] showed that the materials (e.g., glass, plaster, and wood) feature a greater reflectivity for TE polarization than for transverse-magnetic (TM) polarization. Hence, this paper only considers TE polarization and perfect antenna steering.
