Movable antenna (MA) and reconfigurable intelligent surface (RIS) technologies provide additional controllable degrees of freedom for improving wireless transmission. However, in RIS-enhanced MA systems, channel state information (CSI) uncertainties, transceiver hardware impairments (HWIs), and finite-resolution RIS ph...

Automatic modulation classification (AMC) has been a critical task in non-cooperative communication systems, yet the application of deep learning to this domain faces challenges. In this letter, we propose a multi-level spatiotemporal framework for AMC. The model integrates a series of fundamental deep learning compone...
The rapid proliferation of the Internet of Things (IoT) demands wireless technologies balancing energy efficiency, long-range coverage, and reliable transmission. As a leading low-power wide-area network (LPWAN) solution, LoRa modulation excels in robustness and low-power consumption but faces bottlenecks of limited sp...
