The channel estimation procedure is quite challenging in Terahertz (THz)-band communication systems due to the beam-split effect. This occurrence emerges in ultra-broadband THz signals that have large fractional bandwidths. In such a scenario, the components of the THz path at various subcarriers split into diverse spatial directions with the consequence of array gain loss. This results in a beam ...Show More
