Beam Training for RIS-Aided ISAC Systems
Jinho Yang, Hyeongtaek Lee, Junil Choi
As a key technology for 6G, integrated sensing and communication (ISAC) is receiving considerable attention, and deploying a reconfigurable intelligent surface (RIS) can enhance bo…
Efficient Upper Mid-Band Spectrum Sensing with Multiple Signals
Yongjun Kim, Ali Rasteh, Sundeep Rangan +1
Spectrum sensing is a fundamental problem in the upper mid-band, where spectrum resources are shared with incumbent systems. This paper considers frequency-domain occupancy estimat…
A Self-Calibrating SDR for High Fidelity Beam- and Null-forming Arrays
Yongjun Kim, Aditya Dhananjay, Sundeep Rangan +5
Null forming is increasingly essential in modern wireless systems for spectrum-sharing, anti-jamming, and covert communications in contested and congested environments. Achieving d…
Efficient Solvers for Coupling-Aware Beamforming in Continuous Aperture Arrays
Geonhee Lee, Kwonyeol Park, Hyeongjun Park +2
In continuous aperture arrays (CAPAs), careful consideration of the underlying physics is essential, among which electromagnetic (EM) mutual coupling plays a critical role in beamf…
Evolution of UE in Massive MIMO Systems for 6G: From Passive to Active
Kwonyeol Park, Hyuckjin Choi, Geonho Han +4
As wireless networks continue to evolve, stringent latency and reliability requirements and highly dynamic channels expose fundamental limitations of gNB-centric massive multiple-i…
