“…LOS MIMO is particularly valuable in the mmWave and THz frequencies, where the wavelength λ is small and hence the Rayleigh distance -which sets the maximum range of such systems -is large. Indeed, there have been several demonstrations in the mmWave spectrum [5], and, with the advancement of communication systems in the THz and sub-THz bands [6], there has been growing interest in high-rank LOS MIMO in higher frequencies as well [7] -see, for example, some recent work at 140 GHz [8], [9].…”

“…The spherical wave from this source can then be easily modeled for arbitrarily wide aperture arrays. sub-THz systems [9], [10], [11] -NLOS paths may be present from ground clutter when serving street-level radio units. In this work, we will use the term wide aperture MIMO, instead of LOS MIMO, since we are interested in cases where the systems operate in such NLOS settings.…”

High-rank line-of-sight (LOS) MIMO systems have attracted considerable attention for millimeter wave and THz communications. The small wavelengths in these frequencies enable spatial multiplexing with massive data rates at long distances. Such systems are also being considered for multi-path non-LOS (NLOS) environments. In these scenarios, standard channels models based on plane waves cannot capture the curvature of each wave front necessary to model spatial multiplexing. This work presents a novel and simple multi-path wireless channel parametrization where each path is replaced by a LOS path with a reflected image source. The model fully captures the spherical nature of each wave front and uses only two additional parameters relative to the standard plane wave model. Moreover, the parameters can be easily captured in standard ray tracing. The accuracy of the approach is demonstrated on detailed ray tracing simulations at 28 GHz and 140 GHz in a dense urban area.
