9:30am - 10:30am
Offline Venue: E4-201;Zoom ID: 965 3877 7912, Passcode: iott

In the era of modern machine-type communications (MTC), efficiently identifying active Internet-of-Things (IoT) devices during the random access phase is crucial. Existing single-cell activity detection methods face significant computational complexity and delays, making real-time implementation difficult. The challenge intensifies with cell-free massive MIMO due to asynchronous IoT devices over large areas and capacity-limited fronthaul links. This talk will explore deep learning techniques for single-cell activity detection, ensuring real-time implementation and adaptability across varying device numbers. For cell-free massive MIMO, I will introduce a communication-efficient end-to-end learning framework that maintains high detection performance with minimal fronthaul overhead. These advancements promise to enhance the efficiency and reliability of IoT networks, paving the way for more robust MTC systems.
