“…To overcome such challenges, beamforming practices have been forced to rely on fewer RF chains. Although analog beamforming is implemented for enhancing spatial resolution in the MIMO radars, it is limited in the application of the communication domain since all processing has been done in the RF domain [8]. By utilizing the high gain, the analog beamforming is used in distinctive wireless personal area networks (WPAN) and wireless fidelity (Wi-Fi) to get a high data rate.…”

“…In M-MIMO, a base station with 100 or 1000 transmitter antenna elements simultaneously transmits data to tens or hundreds of reception antenna elements. Multiple antenna elements can help to improve spectral efficiency and capacity [4,5]. Again, this results in interference, which can be mitigated by using beamforming antennas rather than standard antennas.…”

In 5G mobile communication networks, millimeter-wave (mmWave) technology plays a key role. To deal with the problem of path loss that happens in the mmWave band, competent beamforming employing a large antenna array is required. Fully digital beamforming approaches currently require separate radio frequency chains (RF chains) for each antenna, which adds to the computational complexity and hardware expense. In a multi-user environment, fully digital beamforming suffers from a larger antenna array layout, whereas analog beamforming solutions are prone to numerous performance concerns. Hybrid beamforming, on the other hand, offers a promising solution for multi-user mmWave communication. This work proposes a two-dimensional overlapping partially connected (2D-OPC) sub-array structure to reduce the antenna structure's hardware complexity and cost. The suggested technique comprises several sub-arrays that are overlapped in 2D space in the form of a Uniform Planar Array (UPA). The suggested scheme's performance is assessed using Kalman-based hybrid beamforming, which exhibits a considerable increase in spectral efficiency when compared to existing hybrid beamforming techniques. The suggested technique, which uses Kalman based hybrid beamforming and 2D-OPC provides 3.14% and 4.96% improvement over the MMSE hybrid beamforming and ZF pre-coding technique respectively.
