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…
Excess Distortion Exponent Analysis for Semantic-Aware MIMO Communication Systems
Yuxuan Shi, Shuo Shao, Yongpeng Wu +3
In this paper, the analysis of excess distortion exponent for joint source-channel coding (JSCC) in semantic-aware communication systems is presented. By introducing an unobservabl…
Joint Device Detection, Channel Estimation, and Data Decoding with Collision Resolution for MIMO Massive Unsourced Random Access
Tianya Li, Yongpeng Wu, Mengfan Zheng +5
In this paper, we investigate a joint device activity detection (DAD), channel estimation (CE), and data decoding (DD) algorithm for multiple-input multiple-output (MIMO) massive u…
Optimization Techniques in Reconfigurable Intelligent Surface Aided Networks
Biqian Feng, Junyuan Gao, Yongpeng Wu +3
Reconfigurable intelligent surface (RIS)-aided networks have been investigated for the purpose of improving the system performance. However, the introduced unit modulus phase shift…
Large-Scale MIMO Secure Transmission with Finite Alphabet Inputs
Yongpeng Wu, Jun-Bo Wang, Jue Wang +2
In this paper, we investigate secure transmission over the large-scale multiple-antenna wiretap channel with finite alphabet inputs. First, we show analytically that a generalized…
Transmit Designs for the MIMO Broadcast Channel with Statistical CSI
Yongpeng Wu, Shi Jin, Xiqi Gao +2
We investigate the multiple-input multiple-output broadcast channel with statistical channel state information available at the transmitter. The so-called linear assignment operati…
