Autonomous Discovery of Wireless Communications Algorithms
Fayçal Aït Aoudia, Jakob Hoydis, Sebastian Cammerer +4
Large language model (LLM)-driven evolutionary search is an emerging algorithm-discovery paradigm that has already produced novel results in several scientific fields. Yet its appl…
The AI Telco Engineer: Toward Autonomous Discovery of Wireless Communications Algorithms
Fayçal Aït Aoudia, Jakob Hoydis, Sebastian Cammerer +3
Agentic AI is rapidly transforming the way research is conducted, from prototyping ideas to reproducing results found in the literature. In this paper, we explore the ability of ag…
A 0.32 mm 100 Mb/s 223 mW ASIC in 22FDX for Joint Jammer Mitigation, Channel Estimation, and SIMO Data Detection
Jonas Elmiger, Fabian Stuber, Oscar Castañeda +2
We present the first single-input multiple-output (SIMO) receiver ASIC that jointly performs jammer mitigation, channel estimation, and data detection. The ASIC implements a recent…
A Jammer-Resilient 2.87 mm 1.28 MS/s 310 mW Multi-Antenna Synchronization ASIC in 65 nm
Flurin Arquint, Oscar Castañeda, Gian Marti +1
We present the first ASIC implementation of jammer-resilient multi-antenna time synchronization. The ASIC implements a recent algorithm that mitigates jamming attacks on synchroniz…
Sparse MIMO-OFDM Channel Estimation via RKHS Regularization
James Delfeld, Gian Marti, Chris Dick
We propose a method for channel estimation in multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) wireless communication systems. The method exp…
Joint Jammer Mitigation and Data Detection
Gian Marti, Christoph Studer
Multi-antenna (or MIMO) processing is a promising solution to the problem of jammer mitigation. Existing methods mitigate the jammer based on an estimate of its spatial signature t…
