Abstract

Terahertz (THz) transmission is a promising strategy for future 6G networks, offering ultra-wide bandwidth. Effective channel modeling and precoding techniques are essential for achieving required coverage and addressing significant path loss in THz communications. In this paper, we comprehensively examine the major THz precoding algorithms for future 6G networks, focusing on their significant challenges and prospects. We discriminate between millimeter-wave and THz channels and uncover issues with THz precoding, such as distance-dependent direction loss, beam split impact, and excessive power usage. To solve these issues, three distinct THz precoding systems, such as hybrid precoding, analog beamforming, and delay-phase precoding, are introduced and their performance is compared.

Keywords: Terahertz communication, 6G Networks, Millimeter-wave, Precoding System, Beam forming.
