MIMO Channels Modeling for Terahertz Radio Communications Systems

THz channel is a multipath channel that causes large differences between transmitted and received signals. To do transmission over this environment, the channel model must be realized. In fact, modeling the THz channel will allow researchers to develop the THz communication system, as well as to establish an effective communication algorithm, which could improve the data transmission. In this work, we derived mathematical expressions defining an analytical model of the THz MIMO channel based on correlation. Moreover, we focused on the knowledge and modeling of the THz MIMO propagation channel in order to develop suitable tools when analyzing the performance of a MIMO transmission chain. Simulations of the transfer function and impulse response have been carried out in order to validate the proposed model.
