1. Sensing-Based Communication: A Non-Orthogonal Passive Reflection Framework for ISAC
   Source: eess.SP (Signal Processing)
   Link: https://arxiv.org/abs/2611.08809
   While integrating uplink without disrupting the primary downlink remains a critical challenge for existing reflective communication systems, this paper proposes a non-orthogonal passive integrated sensing and communication (ISAC) mechanism termed Sensing-based Communication.

   Source: eess.IV (Image and Video Processing)
   Link: https://arxiv.org/abs/2607.16714

3. On PMU Adequacy for Wideband Dynamics Tracking Beyond Attenuation Assumptions
   Source: eess.SP (Signal Processing)
   Link: https://arxiv.org/abs/2611.09789
   Recent work highlights the inadequacy of standard synchrophasors in capturing high-frequency grid dynamics, including data center oscillations, primarily due to filtering and windowing attenuation during phasor estimation.
4. StreamAZ: Line-by-Line SAR Focusing with State Space Models
   Source: eess.IV (Image and Video Processing)
   Link: https://arxiv.org/abs/2605.10340
   Conventional focusing methods for Synthetic Aperture Radar (SAR) employ block-wise processing efficiently but remain latency-heavy processes that prevent the realisation of a closed-loop cognitive SAR system.
5. Payload-Blind Bistatic Delay-Doppler Sensing with Phase-Injected Chirps in CE-OFDM
   Source: eess.SP (Signal Processing)
   Link: https://arxiv.org/abs/2611.09687
   Constant-envelope orthogonal frequency-division multiplexing (CE-OFDM) preserves a unit-magnitude sample envelope, but its Hermitian-symmetric structure makes dedicated sensing pilots costly, and additive pilots disrupt this envelope.
6. prNet: Data-Driven Phase Retrieval via Stochastic Refinement
   Source: eess.IV (Image and Video Processing)
   Link: https://arxiv.org/abs/2507.09608
   Phase retrieval is an ill-posed inverse problem in which existing methods often struggle to balance reconstruction fidelity and perceptual quality.
7. Beyond Feasibility: Efficient and Robust On-Device Localization with UWB Concurrent Transmissions
   Source: eess.SP (Signal Processing)
   Link: https://arxiv.org/abs/2611.09619
   Concurrent transmissions (CTX) enable an ultra-wideband (UWB) tag to range to, or self-localize from, multiple nodes with a single frame reception, significantly improving update rate and energy efficiency compared to traditional approaches.
8. A Cytology Dataset for Early Detection of Oral Squamous Cell Carcinoma
   Source: eess.IV (Image and Video Processing)
   Link: https://arxiv.org/abs/2506.09661
   Oral squamous cell carcinoma OSCC is a major global health burden, particularly in several regions across Asia, Africa, and South America, where it accounts for a significant proportion of cancer cases.
9. Multi-Mode Pinching-Antenna-Based OFDM Systems: A Robust Design Perspective
   Source: eess.SP (Signal Processing)

   Source: eess.IV (Image and Video Processing)
   Link: https://arxiv.org/abs/2611.08731

   Integrated sensing and communication (ISAC) has emerged as a promising paradigm for future wireless networks.
14. Subliminal Learning in Vision-Language Models
   Source: eess.IV (Image and Video Processing)
   Link: https://arxiv.org/abs/2611.08538
   Subliminal learning is a phenomenon in large language models (LLMs) where a teacher passes a hidden preference to a student through training data unrelated to that preference.
15. A Hybrid Digital/Analog Polyphase Filtering Approach for High-Speed RF-DACs
   Source: eess.SP (Signal Processing)
   Link: https://arxiv.org/abs/2611.09461
   This paper proposes a hybrid polyphase interpolation for RF-DACs that removes the need for full-rate digital commutation by using passive combining on the RF-DAC itself.
16. Super-resolved digital terrain models for GEDI geolocation correction: agreement with airborne LiDAR DTM-based corrections at the beam level, not the footprint
   Source: eess.IV (Image and Video Processing)
   Link: https://arxiv.org/abs/2611.09854
