Next-generation broadband wireless networks must minimize energy consumption and hardware complexity while also achieving great spectral efficiency. Addressing this difficulty, this work develops an adaptive hybrid analog–digital beamforming framework for fifth-generation (5G) millimeter-wave (mmWave) MIMO cellular systems. The suggested method uses analog on-off excitation to selectively activate radiating elements within each vertical antenna array, dynamically synthesizing beams based on traffic demands in real time. By doing away with costly and mechanically complicated beam-steering systems, this method greatly simplifies the transceiver architecture. To enable effective digital processing, each vertical array is part of a circular antenna design and is powered by a separate radio-frequency (RF) chain. A unique system-level simulator that complies with the most recent 3GPP 5G channel models is created in order to thoroughly assess system performance. To offer statistically sound performance evaluations, extensive Monte Carlo simulations are carried out for various MIMO configurations. The suggested adaptive beamforming technique significantly improves important wireless performance metrics, such as user blocking probability and total downlink transmission power, according to simulation results. Notably, depending on the permitted transmission overhead, the adaptive technique considerably lowers the number of active antenna elements for a MIMO setup consisting of 15 vertical antenna arrays with 10 radiating elements per array as compared to traditional static beam grid approaches. Additionally, significant reductions in downlink power consumption and blockage probability are obtained when the number of radiating elements is fixed. Overall, the results show that adaptive hybrid beamforming is a viable option for future mm-Wave network architectures since it provides a scalable, energy-efficient, and hardware-simplified solution for dense and complicated 5G cellular installations.
