Geometrical-Empirical Channel Propagation Model for Human Presence at 60 GHz

Previous efforts to develop simulation and/or measurement-based channel propagation models for the effect of human blockage on millimeter-wave communication systems have yielded important results, but lack either accuracy, generality, or simplicity. To fill that void, in this paper we propose a hybrid geometrical-empirical model presence; refer it as presence because reflection from body before and after occurs addition diffraction around during (as previous efforts) is incorporated. Specifically, modeled superposition main transmission path reflected diffracted paths body; geometrical component accounts phase each while empirical its amplitude. validate proposed extract parameters, an exhaustive measurement campaign with 120 scenarios, comprising varying subjects transmitter-human-receiver configurations, was conducted; total 180,000 acquisitions recorded our precision, state-of the-art 60-GHz sounder. The overall shown be computationally efficient yet general enough accurately represent wide range scenarios.
