Introduction

Brain-Computer Interfaces (BCIs) have emerged as groundbreaking tools for decoding human brain activity and translating it into actionable commands for external devices. However, the success of BCIs heavily relies on the quality of the recorded Electroencephalogram (EEG) signals. EEG signals are often contaminated by various types of noise, including physiological artifacts and environmental interferences, which can compromise the accuracy and reliability of BCI systems. In this context, adaptive wavelet denoising techniques have shown promise in effectively enhancing EEG signals. This paper provides an in-depth exploration of adaptive wavelet denoising methods and their application in improving the signal-to-noise ratio of EEG signals for robust and efficient Brain-Computer Interfaces. Brain-Computer Interfaces have gained significant attention in recent years due to their potential in enabling direct communication between the brain and external devices. EEG signals serve as the primary source of information for BCIs, making it crucial to ensure the highest signal quality possible. However, EEG signals are susceptible to various sources of noise, such as muscle artifacts, eye movements and environmental interferences. Adaptive wavelet denoising has emerged as a powerful tool for mitigating these challenges, providing an effective means to enhance the reliability of EEG signals for BCI applications [1].
