Over-the-Air Diagnosis of Defective Elements in Intelligent Reflecting Surface
Ziyi Zhao, Zhaorui Wang, Lin Zhou +4
Due to circuit failures, defective elements that cannot adaptively adjust the phase shifts of their impinging signals in a desired manner may exist on an intelligent reflecting sur…
Combating Multi-path Interference to Improve Chirp-based Underwater Acoustic Communication
Wenjun Xie, Enqi Zhang, Lizhao You +3
Linear chirp-based underwater acoustic communication has been widely used due to its reliability and long-range transmission capability. However, unlike the counterpart chirp techn…
Reducing Channel Estimation and Feedback Overhead in IRS-Aided Downlink System: A Quantize-then-Estimate Approach
Rui Wang, Zhaorui Wang, Liang Liu +2
Channel state information (CSI) acquisition is essential for the base station (BS) to fully reap the beamforming gain in intelligent reflecting surface (IRS)-aided downlink communi…
Quick and Reliable LoRa Physical-layer Data Aggregation through Multi-Packet Reception
Lizhao You, Zhirong Tang, Pengbo Wang +3
This paper presents a Long Range (LoRa) physical-layer data aggregation system (LoRaPDA) that aggregates data (e.g., sum, average, min, max) directly in the physical layer. In part…
