MITIGATION OF SELF-INTERFERENCE IN BIDIRECTIONAL FULLDUPLEX MIMO LINK USING MULTI ANTENNA TRANSCEIVER [PDF]
Journal of Engineering Science and Technology, 2016 Communication between two multi antenna full duplex transceivers using bidirectional MIMO links faces a major problem of self-interference of signals. Suppression in spatial domain and cancellation in time domain are the two methods that can be adopted ...

On Cancellation Capability of Full-Duplex RF Self-Interference Cancellation Schemes
Mobile Information Systems, 2019 In this work, we study the self-interference cancellation (SIC) capability of two basic radio frequency (RF) SIC schemes: auxiliary antenna cancellation and multireconstruction-path (MRP) cancellation (including particular two-reconstruction-path balun cancellation), and derive their cancellation capability in detail.

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, EarlyView.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
