“…Additionally, they help achieve maximum beamforming gain and keep the interference that PU experiences within a predetermined threshold. We can also find a sub-optimal solution to the problem (19) by deriving the lower bound of the objective function. An alternative solution to design the V RF is as follows:…”

“…It is worth noting that the characteristics of mm-wave channels are different compared to the lower part of the frequency spectrum due to the smaller wavelength of transmitted signals. For instance, huge path loss, limited propagation paths, lower diffraction, and highly directional wireless channels are associated with mm-wave frequencies [ 19 ]. To overcome the poor characteristics of mm-wave channels, the combination of large-scale MIMO and hybrid beamforming is considered the most attractive solution [ 20 ].…”

“…Millimeter wave technology has received significant attention due to its large bandwidth. The combination of millimeter wave and massive MIMO can effectively improve the bandwidth and spectrum utilization of the system [5,6]. On the one hand, the millimeter wavelength is very short, which is conducive to the deployment of a large number of antennas in the system.…”
