This paper tackles the problem of multiple-input multiple-output communication with 1-bit digital-to-analog and analog-to-digital converters. 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. ...
This paper tackles the problem of multiple-input multiple-output communication with 1-bit digital-to-analog and analog-to-digital converters. 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.
