Coordinated Multipoint Anti-jamming Beam Pattern Synthesis: From AI Accelerated Algorithm to Hardware Implementation
Zilong Wang, Cheng Zhang, Zhilei Zhang +3
This paper presents a deep unfolding-supported coordinated multipoint beam pattern synthesis (DUCoMP-BPS) scheme to overcome the high complexity, poor adaptability, and limited sca…
Joint Detection and Angle Estimation for Multiple Jammers in Beamspace Massive MIMO
Pengguang Du, Cheng Zhang, Changwei Zhang +2
In this paper, we study the joint detection and angle estimation problem for beamspace multiple-input multiple-output (MIMO) systems with multiple random jamming targets. An iterat…
Jamming Detection and Channel Estimation for Spatially Correlated Beamspace Massive MIMO
Pengguang Du, Cheng Zhang, Yindi Jing +3
In this paper, we investigate the problem of jamming detection and channel estimation during multi-user uplink beam training under random pilot jamming attacks in beamspace massive…
Joint Optimization of Data- and Model-Driven Probing Beams and Beam Predictor
Tianheng Lu, Fan Meng, Zhilei Zhang +3
Hierarchical search in millimeter-wave (mmWave) communications incurs significant beam training overhead and delay, especially in a dynamic environment. Deep learning-enabled beam…
