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.”

Random Multiplexing for Robust Wireless Communication

Published:Dec 30, 2025 08:58
1 min read
ArXiv

Analysis

This paper introduces a novel random multiplexing technique designed to improve the robustness of wireless communication in dynamic environments. Unlike traditional methods that rely on specific channel structures, this approach is decoupled from the physical channel, making it applicable to a wider range of scenarios, including high-mobility applications. The paper's significance lies in its potential to achieve statistical fading-channel ergodicity and guarantee asymptotic optimality of detectors, leading to improved performance in challenging wireless conditions. The focus on low-complexity detection and optimal power allocation further enhances its practical relevance.
