Ultra-wideband THz/IR Metamaterial Absorber based on Doped Silicon
Huafeng Liu, Kai Luo, Danhua Peng +2
Metamaterial-based absorbers have been extensively investigated in the terahertz (THz) range with ever increasing performances. In this paper, we propose an all-dielectric THz abso…
Spectral Efficiency Analysis of Multi-Cell Massive MIMO Systems with Ricean Fading
Pei Liu, Kai Luo, Da Chen +2
This paper investigates the spectral efficiency of multi-cell massive multiple-input multiple-output systems with Ricean fading that utilize the linear maximal-ratio combining dete…
Spectral Efficiency Analysis of Cell-Free Massive MIMO Systems with Zero-Forcing Detector
Pei Liu, Kai Luo, Da Chen +1
In this paper, we firstly derive two approximations of the achievable uplink rate with the perfect/imperfect channel state information (CSI) in cell-free massive multi-input multi-…
Beam Selection for MmWave Massive MIMO Systems Under Hybrid Transceiver Architecture
Qiu Shuang, Luo Kai, Jiang Tao
Hybrid analog/digital precoding is a promising technology to cut down hardware cost in massive multi-input multi-output (MIMO) systems at millimeter wave frequencies. In this lette…
FDM-Structured Preamble Optimization for Channel Estimation in MIMO-OQAM/FBMC Systems
Wenfeng Liu, Da Chen, Kai Luo +2
