Beam-Squint Mitigating for Reconfigurable Intelligent Surface Aided Wideband MmWave Communications
Yun Chen, Da Chen, Tao Jiang
In this paper, we focus our attention on the mitigation of beam squint for reconfigurable intelligent surface (RIS) aided wideband millimeter wave (mmWave) communications. Due to t…
KPI/KQI-Driven Coordinated Multi-Point in 5G: Measurements, Field Trials, and Technical Solutions
Guochao Song, Wei Wang, Da Chen +1
The fifth generation (5G) systems are expected to be able to support massive number of wireless devices and intense demands for high data rates while maintaining low latency. Coord…
A Covariance-Based Hybrid Channel Feedback in FDD Massive MIMO Systems
Shuang Qiu, David Gesbert, Da Chen +1
In this paper, a novel covariance-based channel feedback mechanism is investigated for frequency division duplexing (FDD) massive multi-input multi-output (MIMO) systems. The conce…
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…
Smoothed SVD-based Beamforming for FBMC/OQAM Systems Based on Frequency Spreading
Yu Qiu, Daiming Qu, Da Chen +1
The combination of singular value decomposition (SVD)-based beamforming and filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) has not been successful…
Millimeter-Wave Massive MIMO Systems Relying on Generalized Sub-Array-Connected Hybrid Precoding
Yun Chen, Da Chen, Tao Jiang +1
In this paper, we consider a generalized sub-array-connected (GSAC) architecture for arbitrary radio frequency (RF) chain and antenna configurations, where the number of RF chains…
