Feedforward Nonlinear Equalizer for Short- to Medium-Reach Wireline Links
Kunmo Kim, Paul Kwon, Elad Alon +1
This paper presents a feedforward nonlinear equalizer (FFNE) framework for short- to medium-reach wireline links that removes the feedback-timing bottleneck of decision-feedback eq…
A Learning Method for Optimal Chirp Predistortion
Averal N. Kandala, Ali M. Niknejad
This article introduces the "chart & chirp" method of one-shot, in situ VCO tuning curve estimation, learning, and predistortion, which provides an alternative to prevailing LMS-ba…
Configurable γ Photon Spectrometer to Enable Precision Radioguided Tumor Resection
Rahul Lall, Youngho Seo, Ali M. Niknejad +1
Surgical tumor resection aims to remove all cancer cells in the tumor margin and at centimeter-scale depths below the tissue surface. During surgery, microscopic clusters of diseas…
Spatial-to-Spectral Harmonic-Modulated Arrays for 6G Multi-Beam MIMO
Jose Guajardo, Ali Niknejad
This article presents an overview and analysis of spatial-to-spectral harmonic-modulated arrays (SHAs). Compared to traditional analog or digital beamforming arrays, SHAs enable co…
Open-source End-to-End Digital Beamforming System Modeling
Jose Guajardo, Ali Niknejad
Digital beamforming forms the foundation for massive MIMO in 6G wireless communications. At their core, digital beamforming architectures provide key benefits such as faster beam s…
