Efficient Multi-Beam Training For Terahertz Wireless communications
Songjie Yang, Zhongpei Zhang, Zhenzhen Hu +2
Although Terahertz communication systems can provide high data rates, it needs high directional beamforming at transmitters and receivers to achieve such rates over a long distance…
An Off-grid Compressive Sensing Strategy for the Subarray Synthesis of Non-uniform Linear Arrays
Songjie Yang, Wanting Lyu, Zhongpei Zhang
With the increasing popularity of large-scale antenna arrays, the subarraying technology becomes more attractive. In this paper, we propose two effective subarraying methods right…
Optimizing the Age of Information in RIS-aided SWIPT Networks
Wanting Lyu, Yue Xiu, Jun Zhao +1
In this letter, a reconfigurable intelligent surface (RIS)-assisted simultaneous wireless information and power transfer (SWIPT) network is investigated. To quantify the freshness…
Spectral and Energy Efficiency of Multicell Massive MIMO With Variable-Resolution ADCs Over Correlated Rayleigh Fading Channels
Youzhi Xiong, Sanshan Sun, Ning Wei +2
This paper analyzes the performance of multicell massive multiple-input and multiple-output (MIMO) systems with variable-resolution analog-to-digital converters (ADCs). In such an…
Sum-Rate Maximization in Distributed Intelligent Reflecting Surfaces-Aided mmWave Communications
Yue Xiu, Wei Sun, Jiao Wu +3
In this paper, we focus on the sum-rate optimization in a multi-user millimeter-wave (mmWave) system with distributed intelligent reflecting surfaces (D-IRSs), where a base station…
