Abstract

Continuous research progress in THz communications including communications and networking paradigms as well as devices and implementation aspects indicate that this technology has the potential to become a key component in future beyond 5G systems. Still, some research challenges have to tackled before, e.g. related to the peculiarities of the highly frequency-selective THz channel resulting in a much longer channel impulse response (CIR) compared to channels in the lower frequency bands. In this paper, first, various equalization techniques such as minimum mean-squared error (MMSE) linear equalization and decision-feedback equalization (DFE) are studied for single-carrier transmission in order to combat the frequency selectivity of a deterministic THz channel. Furthermore, orthogonal frequency-division multiplexing (OFDM) communication with zero-forcing (ZF) equalization is considered, and the performance of single-carrier and multi-carrier transmissions are compared. Secondly, the advantages of a stochastic channel model are pointed out for the analysis of a multiple-input multiple-output (MIMO) transmission, and ZF and MMSE linear frequency-domain equalization are investigated for a single-carrier frequency-division multiple access (SC-FDMA) transmission over a MIMO THz channel. We conclude that SC-FDMA along with MMSE linear equalization is promising for practical THz systems.
