Learning-Based Adaptive IRS Control with Limited Feedback Codebooks
Junghoon Kim, Seyyedali Hosseinalipour, Andrew C. Marcum +3
Intelligent reflecting surfaces (IRS) consist of configurable meta-atoms, which can change the wireless propagation environment through design of their reflection coefficients. We…
Joint Delay and Phase Precoding Under True-Time Delay Constraints for THz Massive MIMO
Dang Qua Nguyen, Taejoon Kim
A new approach is presented to the problem of compensating the beam squint effect arising in wideband terahertz (THz) hybrid massive multiple-input multiple-output (MIMO) systems,…
Link Quality-Guaranteed Minimum-Cost Millimeter-Wave Base Station Deployment
Miaomiao Dong, Taejoon Kim, Minsung Cho +2
Today's growth in the volume of wireless devices coupled with the promise of supporting data-intensive 5G-&-beyond use cases is driving the industry to deploy more millimeter-wave…
Successful Recovery Performance Guarantees of SOMP Under the L2-norm of Noise
Wei Zhang, Taejoon Kim
The simultaneous orthogonal matching pursuit (SOMP) is a popular, greedy approach for common support recovery of a row-sparse matrix. However, compared to the noiseless scenario, t…
Channel Estimation via Successive Denoising in MIMO OFDM Systems: A Reinforcement Learning Approach
Myeung Suk Oh, Seyyedali Hosseinalipour, Taejoon Kim +2
In general, reliable communication via multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) requires accurate channel estimation at the receiver.…
