DOI: 10.1109/tvt.2025.3540067
Abstract: Spatial multiplexing plays a significant role in improving the capacity of multiple-input–multiple-output (MIMO) communication systems. To improve the spectral efficiency (SE) of a point-to-point MIMO system, we exploit the channel reconfiguration capabilities provided by multiple… read more here.
