Two-Bit RIS-Aided Communications at 3.5GHz: Some Insights from the Measurement Results Under Multiple Practical Scenes
Shun Zhang, Haoran Sun, Runze Yu +6
In this paper, we propose a two-bit reconfigurable intelligent surface (RIS)-aided communication system, which mainly consists of a two-bit RIS, a transmitter and a receiver. A cor…
Hybrid mmWave MIMO Systems under Hardware Impairments and Beam Squint: Channel Model and Dictionary Learning-aided Configuration
Hongxiang Xie, Joan Palacios, Nuria González-Prelcic
Low overhead channel estimation based on compressive sensing (CS) has been widely investigated for hybrid wideband millimeter wave (mmWave) multiple-input multiple-output (MIMO) sy…
Efficient Channel Estimator with Angle-Division Multiple Access
Xiaozhen Liu, Jin Sha, Hongxiang Xie +5
Massive multiple-input multiple-output (M-MIMO) is an enabling technology of 5G wireless communication. The performance of an M-MIMO system is highly dependent on the speed and acc…
Time Varying Channel Tracking with Spatial and Temporal BEM for Massive MIMO Systems
Jianwei Zhao, Hongxiang Xie, Feifei Gao +3
In this paper, we propose a channel tracking method for massive multi-input and multi-output systems under both time-varying and spatial-varying circumstance. Exploiting the charac…
