Design of RIS-Aided Differential Reflecting LoRa Modulation With Fractional Spreading Factors

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...

Vision-Wireless Fusion for Multi-User Localization: A Cross-Modal Transformer Approach

Accurate multi-user localization is challenging in complex urban environments, where wireless measurements can become ambiguous under noise, blockage, and multipath, while visual observations provide complementary spatial context. This paper presents a vision-wireless fusion framework for multi-user localization using...
