Improvement of SINR for MIMO channels in terahertz communication

Technological advances have enabled the concept of the Internet of things to be put into practice in many fields from industry to agriculture. A large number of devices connected to the Internet of things pose a huge challenge to data processing and transmission. Terahertz band is a promising solution because of its huge spectrum resource and high transmission rate, but its high space loss limits the communication distance. In this paper, a MIMO channel model for terahertz communication is proposed, which can increase the communication distance by beam shaping and improve the communication capacity by spatial multiplexing. According to the results of simulation analysis, MIMO channel precoding technology can improve the signal-to-noise ratio of communication system.
