ODMA-based MIMO Massive Unsourced Random Access with Soft-Output Polar Codes
Tianya Li, Xiaoran Zhang, Nan Hu +4
This paper investigates the design of the on-off division multiple access (ODMA) transmission scheme for multiple-input multiple-output (MIMO) massive unsourced random access (URA)…
Semantic Noise Aided Secure Image Transmission over MIMO Fading Channels
Xue Han, Biqian Feng, Ting Zhou +5
Existing semantic communications have exhibited satisfactory performance in many tasks, but secure image transmission remains insufficiently explored. We propose a novel secure ima…
Asynchronous MIMO-OFDM Massive Unsourced Random Access with Codeword Collisions
Tianya Li, Yongpeng Wu, Junyuan Gao +4
This paper investigates asynchronous multiple-input multiple-output (MIMO) massive unsourced random access (URA) in an orthogonal frequency division multiplexing (OFDM) system over…
Weighted Sum-Rate Maximization for Movable Antenna-Enhanced Wireless Networks
Biqian Feng, Yongpeng Wu, Xiang-Gen Xia +1
This letter investigates the weighted sum rate maximization problem in movable antenna (MA)-enhanced systems. To reduce the computational complexity, we transform it into a more tr…
Massive Unsourced Random Access for Near-Field Communications
Xinyu Xie, Yongpeng Wu, Jianping An +3
This paper investigates the unsourced random access (URA) problem with a massive multiple-input multiple-output receiver that serves wireless devices in the near-field of radiation…
A Novel RFID Authentication Protocol Based on A Block-Order-Modulus Variable Matrix Encryption Algorithm
Yan Wang, Ruiqi Liu, Tong Gao +5
In this paper, authentication for mobile radio frequency identification (RFID) systems with low-cost RFID sensor tags is studied. Firstly, an adaptive modulus (AM) encryption algor…
