THE DESIGN OF TRANSCEIVERS AND THEIR ASSOCIATED AIR INTERFACE IN SUB-THZ AND THZ FREQUENCY BAND IN 6G NETWORK

Abstract

The development of transceivers and their respective air interfaces within the sub-THz and THz frequency range is a major milestone in the development of the wireless communication technology. The aim of this paper is to design transceivers and their air interfaces in THz frequencies for the 6G network. The idea of exploiting sub-THz frequencies for next-generation wireless communication has generated much research interest and industrial attention. The sub-THz spectrum from 90 GHz to 300 GHz can provide vast bandwidth for transceiver systems, capable of supporting high-speed wireless communication. Thus, wireless communication technologies developing along the vector of sub-THz frequency might serve as a prominent building block for future network infrastructures. This paper highlights transceiver design and air interface development in the sub-THz and THz frequency bands, from transmitter and receiver units optimized for these frequencies. In the design of the physical layer, a major difficulty that arises is coping with phase distortion and limitations imparted by band-limited analog-to-digital converters. The prime objective of this work is, therefore, to introduce novel communication technologies operating within the sub-THz spectrum and meeting the stringent requirements of next-generation wireless applications.
