Abstract
For multi-gigabit wireless transmission in fiber-wireless (FiWi) networks, one of the good promising candidates is terahertz (THz) communications. In order to analyze the performance of THz communication systems, where there exist multiple paths caused by THz signal’s reflections, a proper channel model for describing the THz frequency characteristics and an adequate path selection algorithm is important. By bringing the blocking probability to describe the blocking effect of the propagation signals, this paper provides a modified THz channel model and proposes a path selection algorithm for finding the dominant signal. This paper also analyzes the correlation coefficient between propagation signals. Numerical results reveal that the modified channel model is suitable for describing the blocking effect of the propagation signals in the FiWi indoor environment and the proposed algorithm makes use of path diversity well to achieve the highest data transmission rate.
