With the information-theoretic capacity as benchmark, the complementary strategies of beamforming and equiprobable signaling are contrasted in the regimes of operational interest. Line-of-sight settings under both spherical and planar wavefronts are considered, respectively representative of short and long transmission ranges at mmWave and terahertz frequencies. A judicious combination of beamforming and equiprobable signaling is shown to operate within a modest gap from capacity.application/pdfeng© 2021 IEEE. Personal use of this material is permitted.
