Full-Duplex Wireless Systems: Self-Interference, Signal Processing, and Emerging Applications
In this talk, we explore full-duplex wireless communication, a paradigm that enables simultaneous transmission and reception on the same frequency band, significantly improving spectral efficiency. We outline the motivation and fundamental concepts behind full-duplex systems, followed by an overview of existing architectures. A major focus is on self-interference cancellation techniques, including propagation-based methods and both analog and digital domain approaches, which are critical for practical implementation. We then examine key applications enabled by full-duplex operation, including wireless power transfer, enhanced physical layer security, and intelligent reflective surfaces with simultaneous sensing and communication capabilities. Finally, we highlight current challenges and future research directions, emphasizing opportunities for novel approaches in system design, signal processing, and real-world deployment of full-duplex wireless systems.
