Multi-span optical power spectrum prediction using cascaded learning with one-shot end-to-end measurement

Journal Article Journal of Optical Communications and Networking · January 1, 2025 Scalable methods for optical transmission performance prediction using machine learning (ML) are studied in metro reconfigurable optical add-drop multiplexer (ROADM) networks. A cascaded learning framework is introduced to encompass the use of casc ... Full text Cite

Design and Testbed Deployment of Frequency-Domain Equalization Full Duplex Radios

Journal Article IEEE Transactions on Wireless Communications · January 1, 2025 Full-duplex (FD) wireless can significantly enhance spectrum efficiency but requires effective self-interference (SI) cancellers. RF SI cancellation (SIC) via frequency-domain equalization (FDE), where bandpass filters channelize the SI, is suited for inte ... Full text Cite

Full-Duplex Receiver With Wideband, High-Power RF Self-Interference Cancellation Based on Capacitor Stacking in Switched-Capacitor Delay Lines

Journal Article IEEE Journal of Solid-State Circuits · July 1, 2024 The self-interference (SI) channels in full-duplex (FD) radios have large nano-second-scale delay spreads, which poses a significant challenge in designing SI cancelers that can emulate the SI channel over wide bandwidths. Passive implementations of high d ... Full text Cite
