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…
Fast Transceiver Design for RIS-Assisted MIMO mmWave Wireless Communications
Haiyue Jing, Wenchi Cheng, Xiang-Gen Xia
Due to high bandwidth and small antenna size, millimeter-wave (mmWave) integrated line-of-sight (LOS) multiple-input-multiple-output (MIMO) systems have attracted much attention. R…
Discrete Spectrum Analysis of Vector OFDM Signals
Xiang-Gen Xia, Wei Wang
Vector OFDM (VOFDM) is equivalent to OTFS and is good for time-varying channels. However, due to its vector form, its signal spectrum is not as clear as that of the conventional OF…
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…
