Joint Beamforming Design for IRS-Aided Communications with Channel Estimation Errors
Piao Zeng, Deli Qiao, Haifeng Qian
This paper investigates the joint design of the beamforming scheme in intelligent reflecting surface (IRS) assisted multiuser (MU) multiple-input multiple-output (MIMO) downlink tr…
Alternate Distributed Beamforming for Buffer-Aided Multi-Antenna Relay Systems
Jiayu Zhou, Deli Qiao, Haifeng Qian
In this paper, link selection is investigated in half-duplex (HD) dual-hop cooperative systems with multiple antennas at the relays. Alternate distributed beamforming (ADB) scheme…
Mimicking Full-Duplex Secure Communications for Buffer-Aided Multi-Relay Systems
Jiayu Zhou, Deli Qiao, Haifeng Qian
This paper considers secure communication in buffer-aided cooperative wireless networks in the presence of one eavesdropper, which can intercept the data transmission from both the…
Outage Analysis of Relay-Assisted mmWave Cellular Systems Employing JSDM
Jun Chen, Deli Qiao
In this paper, the outage performance of relay-assisted millimeter wave (mmWave) cellular systems employing joint spatial division and multiplexing (JSDM) is investigated. It is as…
Broadbeam for Massive MIMO Systems
Deli Qiao, Haifeng Qian, Geoffrey Ye Li
Massive MIMO has been identified as one of the promising disruptive air interface techniques to address the huge capacity requirement demanded by 5G wireless communications. For pr…
