In this article, we provide a sufficiently deep understanding of the interplay between the various underlying factors, i.e., CSI overhead and spatial correlation, which result in negative results
The multi-user multiple-input multiple-output (MU-MIMO) systems can greatly improve the system throughput. An efficient user selection and power allocation schemes are essential to achieve
Each fiber optic connector type—SC, LC, ST, E2K, FC, MPO, and MU—has distinct characteristics that make it suitable for specific applications.
