Hybrid Transceiver Optimization for Multi-Hop Communications
Chengwen Xing, Xin Zhao, Shuai Wang +3
Multi-hop communication with the aid of large-scale antenna arrays will play a vital role in future emergence communication systems. In this paper, we investigate amplify-and-forwa…
New Viewpoint and Algorithms for Water-Filling Solutions in Wireless Communications
Chengwen Xing, Yindi Jing, Shuai Wang +2
Water-filling solutions play an important role in the designs for wireless communications, e.g., transmit covariance matrix design. A traditional physical understanding is to use t…
Unified Framework of KKT Conditions Based Matrix Optimizations for MIMO Communications
Chengwen Xing, Yindi Jing, Shuai Wang +4
For multi-input multi-output (MIMO) communication systems, many transceiver design problems involve the optimization of the covariance matrices of the transmitted signals. The deri…
NOMA based Calibration for Large-Scale Spaceborne Antenna Arrays
Yujie Lin, Shuai Wang, Xiangyuan Bu +2
In the parallel calibration for transmitting phased arrays, the calibration receiver must separate the signals belonging to different antenna elements to avoid mutual interference.…
