Attention Mechanism Based Intelligent Channel Feedback for mmWave Massive MIMO Systems
Yibin Zhang, Jinlong Sun, Guan Gui +4
The potential advantages of intelligent wireless communications with millimeter wave (mmWave) and massive multiple-input multiple-output (MIMO) are based on the availability of ins…
Principal Component Analysis Based Broadband Hybrid Precoding for Millimeter-Wave Massive MIMO Systems
Yiwei Sun, Zhen Gao, Hua Wang +4
Hybrid analog-digital precoding is challenging for broadband millimeter-wave (mmWave) massive MIMO systems, since the analog precoder is frequency-flat but the mmWave channels are…
Online Ski Rental for ON/OFF Scheduling of Energy Harvesting Base Stations
Gilsoo Lee, Walid Saad, Mehdi Bennis +2
The co-existence of small cell base stations (SBSs) with conventional macrocell base station is a promising approach to boost the capacity and coverage of cellular networks. Howeve…
Structured Matching Pursuit for Reconstruction of Dynamic Sparse Channels
Xudong Zhu, Linglong Dai, Guan Gui +3
In this paper, by exploiting the special features of temporal correlations of dynamic sparse channels that path delays change slowly over time but path gains evolve faster, we prop…
The Application of MIMO to Non-Orthogonal Multiple Access
Zhiguo Ding, Fumiyuki Adachi, H. Vincent Poor
This paper considers the application of multiple-input multiple-output (MIMO) techniques to non-orthogonal multiple access (NOMA) systems. A new design of precoding and detection m…
Adaptive MIMO Channel Estimation using Sparse Variable Step-Size NLMS Algorithms
Guan Gui, Li Xu, Lin Shan +1
To estimate multiple-input multiple-output (MIMO) channels, invariable step-size normalized least mean square (ISSNLMS) algorithm was applied to adaptive channel estimation (ACE).…
