I’m delighted to share that our paper, “Near-Field Channel Estimation and Joint Angle-Range Recovery in XL-MIMO Systems: A Gridless Super-Resolution Approach,” is now available in Early Access in IEEE Transactions on Signal Processing. [IEEE Xplore] In this work, we formulate near-field channel estimation as a gridless super-resolution problem. The proposed framework eliminates the need for large polar-domain codebooks, avoids basis mismatch and exhaustive two-dimensional grid searches, and enables accurate joint angle–range estimation.

Our paper entitled "A Two-Dimensional Super-Resolution Method for Reconfigurable Intelligent Surface-Assisted Near-Field Localization" has been accepted by SAM2026, which will be held on July in Shenzhen. We will give an oral presentation. Look forward to discussing with you.

A wonderful and inspiring week at ICASSP 2026 in Barcelona. What I enjoyed most was not only the latest advances in signal processing, communications, sensing, and AI, but also the opportunity to exchange ideas with researchers from different communities and perspectives. Many interesting discussions during the conference sparked new thoughts on future research directions. And beyond the conference itself, Barcelona is truly a beautiful and vibrant city — full of creativity, history, and energy. It made this week even more memorable. Looking forward to turning some of these new ideas into future work.
