Speech Title: Low-Altitude UAV ISAC based on Ray Antenna Array

Abstract: Most existing MIMO wireless communication and sensing systems rely on fully-digital or phase shifter-based hybrid analog/digital beamforming architectures, which face critical challenges in high-frequency systems, such as difficulty to implement and poor control accuracy for phase shifters. To address such challenges, this talk will introduce a new MIMO architecture based on the novel ray antenna array (RAA). RAA consists of a large number of low-cost antenna elements, which are arranged in a ray-shaped structure with deliberately designed orientations, thus achieving efficient beam steering without relying on conventional analog or digital beamforming techniques. Compared with the traditional MIMO architecture, RAA system has several appealing advantages, including significantly reduced hardware costs and power consumption, achieving uniform angular resolution in all signal directions, and enhanced beaming gain by enabling antenna elements with higher directivity. Thus, RAA has a wide range of applications in future wireless communications and sensing systems. This talk will first introduce the new MIMO architecture based on RAA, explain its array design and beamforming mechanism in two-dimensional and three-dimensional space, and explore its spatial resolution characteristics. Finally, it will introduce the theories and methods of RAA-based integrated sensing and communication (ISAC) for low-altitude unmanned aerial vehicles (UAVs).

Speech Title: Intelligent Signal Sensing and Recognition for 6G Physical Layer Security

Abstract: The advent of 6G wireless communication marks a paradigm shift toward intelligent, secure, and pervasive connectivity. In this keynote, we explore how Artificial Intelligence (AI) and Deep Learning (DL) are revolutionizing physical-layer security through advanced signal sensing and recognition techniques. As 6G systems encounter increasingly dynamic environments, traditional model-based approaches struggle with complex interference patterns and uncertain channel conditions. To address these challenges, we highlight the role of neural networks in enhancing signal detection, classification, and Specific Emitter Identification (SEI). Through gradient-based optimization and data-driven learning, AI-enabled frameworks can significantly improve model adaptability and accuracy, outperforming conventional rule-based methods. Moreover, we examine how DL is reshaping baseband module functionalities—including modulation recognition, coding/decoding, and detection—toward greater robustness and efficiency. This keynote underscores the strategic importance of integrating intelligent signal processing with next-generation communication systems. By embedding AI into the physical layer, we can build resilient, secure, and intelligent wireless infrastructures capable of meeting the stringent demands of future 6G applications.
