Cooperative Multiterminal Radar and Communication: A New Paradigm for 6G Mobile Networks
Leonardo Leyva, Daniel Castanheira, Adão Silva +2
The impending spectrum congestion imposed by the emergence of new bandwidth-thirsty applications may be mitigated by the integration of radar and classic communications functionali…
Wideband Channel Estimation for IRS-Aided Systems in the Face of Beam Squint
Siqi Ma, Wenqian Shen, Jianping An +1
Intelligent reflecting surfaces (IRSs) improve both the bandwidth and energy efficiency of wideband communication systems by using low-cost passive elements for reflecting the impi…
Antenna Array Diagnosis for Millimeter-Wave MIMO Systems
Siqi Ma, Wenqian Shen, Jianping An +1
The densely packed antennas of millimeter-Wave (mmWave) MIMO systems are often blocked by the rain, snow, dust and even by fingers, which will change the channel's characteristics…
Cooperative 3D Beamforming for Small-Cell and Cell-Free 6G Systems
Sarath Gopi, Sheetal Kalyani, Lajos Hanzo
Three dimensional (3D) resource reuse is an important design requirement for the prospective 6G wireless communication systems. Hence, we propose a cooperative 3D beamformer for us…
Polar-Precoding: A Unitary Finite-Feedback Transmit Precoder for Polar-Coded MIMO Systems
Jinnan Piao, Kai Niu, Jincheng Dai +1
We propose a unitary precoding scheme, namely polar-precoding, to improve the performance of polar-coded MIMO systems. In contrast to the traditional design of MIMO precoding crite…
Dynamic NOMA-Based Computation Offloading in Vehicular Platoons
Dongsheng Zheng, Yingyang Chen, Lai Wei +2
Both the Mobile edge computing (MEC)-based and fog computing (FC)-aided Internet of Vehicles (IoV) constitute promising paradigms of meeting the demands of low-latency pervasive co…
Is NOMA Efficient in Multi-Antenna Networks? A Critical Look at Next Generation Multiple Access Techniques
Bruno Clerckx, Yijie Mao, Robert Schober +7
In this paper, we take a critical and fresh look at the downlink multi-antenna NOMA literature. Instead of contrasting NOMA with OMA, we contrast NOMA with two other baselines. The…
Airplane-Aided Integrated Next-Generation Networking
Muralikrishnan Srinivasan, Sarath Gopi, Sheetal Kalyani +2
A high-rate yet low-cost air-to-ground (A2G) communication backbone is conceived for integrating the space and terrestrial network by harnessing the opportunistic assistance of the…
