Abstract

The development of the Massive Multiple-Input Multiple Output (MIMO) system in recent years has revolutionized wireless communication, delivering significant benefits to energy and spectrum efficiency. While these strategies have been instrumental in the continuous evolution of system performance, traditional static beamforming methods (e.g. Zero-Forcing (ZF), Maximum Ratio Transmission (MRT) and Minimum Mean Square Error (MMSE)) are limited concerning their scalability and reliability on channel state information to a large extent. In this paper, we investigate the techniques of beamforming with machine learning (ML) integration to bypass these limitations and better optimize system performance. This review covers the usage of different approaches to Machine Learning: supervised learning methods (including Neural Networks and Support Vector Machines (SVM). We also study reinforcement learning techniques due to their dynamic optimization features, as well as deep-learning models like Recurrent and Convolutional Neural Networks (RNN/CNN), which are popular for treating big data or temporal dynamics. Our analysis shows several key findings: ML-based methods are effective in improving the performance of beamforming, including enhancing spectral efficiency and reducing energy consumption as well as their robustness with respect to channel state information (CSI) errors. Finally, we conclude by identifying how potential emerging trends such as federated learning and quantum computing can be positioned to overcome these challenges in the future direction of ML-optimized beamforming for massive MIMO systems.

Keywords: Beamforming, Convolutional Neural Networks (CNN), Deep Learning (DL), Machine Learning (ML), Massive MIMO, Reinforcement Learning.
