IEEE ComSoc selected publications: "Terahertz Line-of-Sight MIMO Communication: Theory and Practical Challenges," by H. Do, S. Cho, J. Park, H. -J. Song, N. Lee and A. Lozano, in IEEE Communications Magazine, vol. 59, no. 3, pp. 104-109, March 2021.
This work analyses the wireless communication systems at terahertz bands. In that distant land of tiny wavelengths, antenna arrays can serve for more than power-enhancing beamforming. Defying lower-frequency wisdom, spatial multiplexing becomes feasible even in line-of-sight conditions. Reconfigurable array architectures are put forth that can closely approach such capacity, practical challenges are discussed, and supporting experimental evidence is presented.
