Unmanned aerial vehicle (UAV)-enabled wireless networks provide flexible coverage for ground users in dynamic and infrastructure-limited scenarios. However, when multiple UAV base stations share the same spectrum, system performance is strongly affected by UAV placement, user association, and co-channel interference. T...

Conventional reconfigurable intelligent surfaces (RIS)-aided cell-free massive multiple-input multiple-output (CF mMIMO) networks are inherently constrained by half-space reflection, which limits coverage expansion and flexible deployment. To overcome this issue, simultaneously transmitting and reflecting reconfigurabl...

Wireless networked control systems (WNCSs) have emerged as a key enabler for modern industrial automation, interconnecting sensors, control centers, and actuators via wireless communications. However, conventional architectures based on separate optimization of control and communication lead to inefficient resource uti...

Multivariate Time Series (MTS) anomaly detection is critical for various applications. Yet, most existing methods rely on forecasting or reconstruction-based frameworks, which suffer from inherent uncertainties in handling complex MTS data. The recently emerging imputation-based anomaly detection leverages partial obse...

The integration of reconfigurable intelligent surface (RIS) technology with cell-free massive MIMO (CF mMIMO) enhances wireless network sum-rate performance. This paper proposes a novel segmented RIS-assisted CF mMIMO architecture for downlink transmission, where RIS elements within each segment share a common reflecti...
