Next-generation wireless communication networks will benefit from beamforming gain to utilize higher bandwidths at millimeter wave (mmWave) and terahertz (THz) bands. For high directional gain, a beam management (BM) framework acquires and tracks opt

In this paper, we introduce a simple software-defined-radio (SDR) based prototyping architecture with an FPGA-based real-time RF control implementation that can agnostically interface different mmWave phased antenna array types to a USRP. It is used

In this work, we investigate the accuracy and complexity deviation between using all or selected antenna elements of a massive MIMO array for source localization. In addition, we address the problem of highly resolving the propagation time delay, and

Multi-user massive MIMO is capable of serving at least ten users simultaneously. However, when users are closely located, their high inter-user correlation is undesired; under this condition, these densely packed users must be separated by higher lay

Distributed massive multiple-input multiple-output (DM-MIMO) gives a higher spectral efficiency and enhanced coverage area, compared to collocated massive MIMO (CM-MIMO). In general, for massive MIMO, time division duplex is preferable as it enables
