Beamforming Design for Integrated Sensing and Communications Using Uplink-Downlink Duality
Kareem M. Attiah, Wei Yu
This paper presents a novel optimization framework for beamforming design in integrated sensing and communication systems where a base station seeks to minimize the Bayesian Cramér…
Meta-Learning-Based Fronthaul Compression for Cloud Radio Access Networks
Ruihua Qiao, Tao Jiang, Wei Yu
This paper investigates the fronthaul compression problem in a user-centric cloud radio access network, in which single-antenna users are served by a central processor (CP) coopera…
Active Sensing for Two-Sided Beam Alignment and Reflection Design Using Ping-Pong Pilots
Tao Jiang, Foad Sohrabi, Wei Yu
Beam alignment is an important task for millimeter-wave (mmWave) communication, because constructing aligned narrow beams both at the transmitter (Tx) and the receiver (Rx) is cruc…
Role of Interference Alignment in Wireless Cellular Network Optimization
Gokul Sridharan, Siyu Liu, Wei Yu
The emergence of interference alignment (IA) as a degrees-of-freedom optimal strategy motivates the need to investigate whether IA can be leveraged to aid conventional network opti…
Sparse Beamforming and User-Centric Clustering for Downlink Cloud Radio Access Network
Binbin Dai, Wei Yu
This paper considers a downlink cloud radio access network (C-RAN) in which all the base-stations (BSs) are connected to a central computing cloud via digital backhaul links with f…
Large-Scale MIMO versus Network MIMO for Multicell Interference Mitigation
Kianoush Hosseini, Wei Yu, Raviraj S. Adve
This paper compares two important downlink multicell interference mitigation techniques, namely, large-scale (LS) multiple-input multiple-output (MIMO) and network MIMO. We conside…
