Beam-Squint-Aided Hierarchical Sensing for Integrated Sensing and Communications

Published:Dec 31, 2025 08:42
1 min read
ArXiv

Analysis

This paper introduces a novel hierarchical sensing framework for wideband integrated sensing and communications using uniform planar arrays (UPAs). The key innovation lies in leveraging the beam-squint effect in OFDM systems to enable efficient 2D angle estimation. The proposed method uses a multi-stage sensing process, formulating angle estimation as a sparse signal recovery problem and employing a modified matching pursuit algorithm. The paper also addresses power allocation strategies for optimal performance. The significance lies in improving sensing performance and reducing sensing power compared to conventional methods, which is crucial for efficient integrated sensing and communication systems.
Reference

Dynamic Spectral Shaping for OFDM with Low Complexity

Published:Dec 30, 2025 18:46
1 min read
ArXiv

Analysis

This paper addresses the critical problem of spectral confinement in OFDM systems, crucial for cognitive radio applications. The proposed method offers a low-complexity solution for dynamically adapting the power spectral density (PSD) of OFDM signals to non-contiguous and time-varying spectrum availability. The use of preoptimized pulses, combined with active interference cancellation (AIC) and adaptive symbol transition (AST), allows for online adaptation without resorting to computationally expensive optimization techniques. This is a significant contribution, as it provides a practical approach to improve spectral efficiency and facilitate the use of cognitive radio.
Reference

“The employed pulses combine active interference cancellation (AIC) and adaptive symbol transition (AST) terms in a transparent way to the receiver.”

Dynamic Channel Knowledge Map Construction for MIMO-OFDM

Published:Dec 29, 2025 13:53
1 min read
ArXiv

Analysis

This paper addresses the challenge of channel estimation in dynamic environments for MIMO-OFDM systems. It proposes a novel method for constructing a Dynamic Channel Knowledge Map (CKM) that accounts for both quasi-static and dynamic channel characteristics, antenna rotation, and synchronization errors. The Bayesian inference framework and two-stage algorithm are key contributions, offering a potentially more accurate and robust approach to channel estimation compared to existing methods designed for quasi-static environments. The focus on low-overhead and high-performance channel estimation is crucial for practical applications.
