Pseudo-doppler aided cancellation of self-interference in full-duplex communications

Frontiers in Signal Processing, 2022
In this work, a novel scheme is proposed to enhance the self-interference (SI) cancellation in full-duplex communications. Beyond conventional SI cancellation schemes that rely on the SI suppression, our proposed scheme exploits periodic antenna ...

SDR Proof-of-Concept of Full-Duplex Jamming for Enhanced Physical Layer Security

Sensors, 2021
In order to secure wireless communications, we consider the usage of physical-layer security (PLS) mechanisms (i.e., coding for secrecy mechanisms) combined with self-interference generation.

Performance on ICI Self-Cancellation in FFT-OFDM and DCT-OFDM System

Journal of Function Spaces, 2015
In orthogonal frequency division multiplexing (OFDM) system, the existence of frequency offset in AWGN channel affects the orthogonality among the subcarriers and consequently introduces the intercarrier interference (ICI). The paper investigates new ICI

Performance analysis of broadband self-interference cancellation at RF domain in co-frequency co-time full duplex systems

Tongxin xuebao, 2016
Due to the lack of performance analysis of the RF domain broadband self-interference cancellation algorithms in the co-time and co-frequency full duplex system,the multi-tap RF domain self-interference cancellation structure were considered,and the ...

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.

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 ...

Phase Compensation Self-interference Cancellation Method for Full-duplex Single-Carrier Underwater Acoustic Communication

水下无人系统学报
Aiming at the problem that the self-interference cancellation performance is degraded due to the phase mismatch between the transmitting and receiving samples in the in-band full-duplex underwater acoustic communication, this paper proposed a method to ...

Wideband RF Self-Interference Cancellation Circuit for Phased Array Simultaneous Transmit and Receive Systems

IEEE Access, 2018
With the growing demand for spectrum utilization, the concept of full duplex transceivers has become attractive. These simultaneous transmit and receive systems (STAR) are attractive as they double bandwidth utilization. To realize STAR, we must suppress

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

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.
