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.”

Short Sums of Trace Functions in Function Fields

Published:Dec 30, 2025 08:43
1 min read
ArXiv

Analysis

This paper investigates the behavior of trace functions in function fields, aiming for square-root cancellation in short sums. This has implications for problems in analytic number theory over finite fields, such as Mordell's problem and the variance of Kloosterman sums. The work focuses on specific conditions for the trace functions, including squarefree moduli and slope constraints. The function field version of Hooley's Hypothesis R* is a notable special case.

    Proactive Hearing Assistant Uses AI to Filter Voices in Crowded Environments

    Published:Dec 8, 2025 16:00
    1 min read
    IEEE Spectrum

    Analysis

    This article discusses a promising AI-powered hearing aid that aims to improve speech intelligibility in noisy environments. The approach of using turn-taking patterns to identify conversation partners is novel and potentially more effective than traditional noise cancellation. The reliance on directional audio filtering and the user's own speech as an anchor seems crucial for the system's accuracy. However, the article lacks details on the system's performance in real-world scenarios, such as its accuracy rate, limitations in different acoustic environments, and user feedback. Further research and development are needed to address these gaps and assess the practical viability of this technology. The ethical implications of selectively filtering voices also warrant consideration.
