An Analog Baseband Approach for Designing Full-Duplex Radios

, 2013
Recent wireless testbed implementations have proven that full-duplex communication is in fact possible and can outperform half-duplex systems. Many of these implementations modify existing half-duplex systems to operate in full-duplex.

Novel Cancellation Techniques and Throughput Analysis for 6G Full-Duplex Wireless System

Space: Science & Technology
Recent researches show that it is possible to achieve full-duplex system if the self-interference signal could be cancelled completely for 6G research. The majority of the overall self-interference cancellation is contributed by passive cancellation. The

Self-Interference Cancellation Using Time-Domain Phase Noise Estimation in OFDM Full-Duplex Systems

, 2016
In full-duplex systems, oscillator phase noise (PN) problem is considered the bottleneck challenge that may face the self-interference cancellation (SIC) stage especially when orthogonal frequency division multiplexing (OFDM) transmission scheme is ...

Multimodal Human–Robot Interaction Using Human Pose Estimation and Local Large Language Models

Advanced Robotics Research, EarlyView.
A multimodal human–robot interaction framework integrates human pose estimation (HPE) and a large language model (LLM) for gesture‐ and voice‐based robot control. Speech‐to‐text (STT) enables voice command interpretation, while a safety‐aware arbitration mechanism prioritizes gesture input for rapid intervention.

RF Self-Interference Cancellation for Radio-Over-Fiber Link Based on Dual Phase Modulation in Sagnac Loop

IEEE Photonics Journal, 2021
The in-band full-duplex (IBFD) systems can send and receive data simultaneously in the same frequency band. Although the electromagnetic interference among RF channels can be released using radio over fiber (RoF) links, the receiving antenna is ...

Active Self-Interference Cancellation Mechanism for Full-Duplex Wireless Transceivers [PDF]

Proceedings of the 9th International Conference on Cognitive Radio Oriented Wireless Networks, 2014
This paper investigates active cancellation techniques for a Full-Duplex transceiver. An auxiliary transmit chain is employed to create the cancellation signal, which is then injected at the receiver RF front-end by using a microstrip cou-pler. Two methods are proposed to calculate the self-interference cancellation signal.
