Digital AirComp with Complement Coding

Published:Dec 31, 2025 11:16
1 min read
ArXiv

Analysis

This paper addresses limitations of analog signals in over-the-air computation (AirComp) by proposing a digital approach using two's complement coding. The key innovation lies in encoding quantized values into binary sequences for transmission over subcarriers, enabling error-free computation with minimal codeword length. The paper also introduces techniques to mitigate channel fading and optimize performance through power allocation and detection strategies. The focus on low SNR regimes suggests a practical application focus.
Reference

“The paper theoretically ensures asymptotic error free computation with the minimal codeword length.”

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.
Reference

“Random multiplexing achieves statistical fading-channel ergodicity for transmitted signals by constructing an equivalent input-isotropic channel matrix in the random transform domain.”
