Self-Calibration for Massive MIMO with Channel Reciprocity and Channel Estimation Errors
De Mi, Lei Zhang, Mehrdad Dianati +3
In time-division-duplexing (TDD) massive multiple-input multiple-output (MIMO) systems, channel reciprocity is exploited to overcome the overwhelming pilot training and the feedbac…
Mobility and Coverage Evaluation of New Radio PDCCH for Point-to-Multipoint Scenario
Hongzhi Chen, De Mi, Belkacem Mouhouche +2
This paper provides the mobility and coverage evaluation of New Radio (NR) Physical Downlink Control Channel (PDCCH) for Point-to-Multipoint (PTM) use cases, e.g., eMBMS (evolved M…
Rate-Splitting for Multigroup Multicast Beamforming in Multicarrier Systems
Hongzhi Chen, De Mi, Zheng Chu +2
In this paper, we consider multigroup multicast transmissions with different types of service messages in an overloaded multicarrier system, where the number of transmitter antenna…
To Learn or Not to Learn: Deep Learning Assisted Wireless Modem Design
S. Xue, A. Li, J. Wang +4
Deep learning is driving a radical paradigm shift in wireless communications, all the way from the application layer down to the physical layer. Despite this, there is an ongoing d…
