Abstract
In this paper, we propose an energy efficient hybrid beamforming architecture for millimeter-wave (mmWave) massive MIMO communication systems operating at 28 GHz, utilizing a 16 × 16 antenna array. The design focuses on minimize the number of RF chains requirements through a dynamic subarray configuration, where the antenna elements are grouped into subarrays that vary according to the channel conditions. To further improve system performance, the successive interference cancellation method utilized in the hybrid beamforming process, effectively mitigating multi-user interference, and improving signal decoding accuracy. The proposed approach balances between system complexity and performance by minimizing the RF chain count while maintaining robust beamforming capabilities. Simulation results demonstrate that our method achieves substantial energy savings and enhanced spectral efficiency compared to traditional hybrid beamforming techniques, making it a feasible approach for futuristic wireless communication system.
