Probabilistic Shaped Multilevel Polar Coding for Wiretap Channel
Li Shen, Yongpeng Wu, Peihong Yuan +3
A wiretap channel is served as the fundamental model of physical layer security techniques, where the secrecy capacity of the Gaussian wiretap channel is proven to be achieved by G…
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…
Channel Estimation for Movable Antenna Communication Systems: A Framework Based on Compressed Sensing
Zhenyu Xiao, Songqi Cao, Lipeng Zhu +3
Movable antenna (MA) is a new technology with great potential to improve communication performance by enabling local movement of antennas for pursuing better channel conditions. In…
Multiuser Communications with Movable-Antenna Base Station: Joint Antenna Positioning, Receive Combining, and Power Control
Zhenyu Xiao, Xiangyu Pi, Lipeng Zhu +2
Movable antenna (MA) is an emerging technology which enables a local movement of the antenna in the transmitter/receiver region for improving the channel condition and communicatio…
Proactive Content Caching Scheme in Urban Vehicular Networks
Biqian Feng, Chenyuan Feng, Daquan Feng +2
Stream media content caching is a key enabling technology to promote the value chain of future urban vehicular networks. Nevertheless, the high mobility of vehicles, intermittency…
A Graph-Based Collision Resolution Scheme for Asynchronous Unsourced Random Access
Tianya Li, Yongpeng Wu, Wenjun Zhang +2
This paper investigates the multiple-input-multiple-output (MIMO) massive unsourced random access in an asynchronous orthogonal frequency division multiplexing (OFDM) system, with…
