Weighted MMSE Precoding for Constructive Interference Region
Yafei Wang, Wenjin Wang, Li You +2
In this paper, we propose a symbol-level precoding (SLP) design that aims to minimize the weighted mean square error between the received signal and the constellation point located…
Spatial Covariance Matrix Reconstruction for DOA Estimation in Hybrid Massive MIMO Systems with Multiple Radio Frequency Chains
Yinsheng Liu, Yiwei Yan, Li You +2
Multiple signal classification (MUSIC) has been widely applied in multiple-input multiple-output (MIMO) receivers for direction-of-arrival (DOA) estimation. To reduce the cost of r…
Energy-Efficient Precoding in Electromagnetic Exposure-Constrained Uplink Multiuser MIMO
Jiayuan Xiong, Li You, Derrick Wing Kwan Ng +2
User electromagnetic (EM) exposure is continuously being exacerbated by the evolution of multi-antenna portable devices. To mitigate the effects of EM radiation, portable devices m…
Energy Efficiency Optimization for Multi-cell Massive MIMO: Centralized and Distributed Power Allocation Algorithms
Li You, Yufei Huang, Di Zhang +3
This paper investigates the energy efficiency (EE) optimization in downlink multi-cell massive multiple-input multiple-output (MIMO). In our research, the statistical channel state…
Deterministic Pilot Design and Channel Estimation for Downlink Massive MIMO-OTFS Systems in Presence of the Fractional Doppler
Ding Shi, Wenjin Wang, Li You +4
Although the combination of the orthogonal time frequency space (OTFS) modulation and the massive multiple-input multiple-output (MIMO) technology can make communication systems pe…
Location-Based Timing Advance Estimation for 5G Integrated LEO Satellite Communications
Wenjin Wang, Tingting Chen, Rui Ding +3
