The design and implementation of the first in-band full duplex WiFi radios that can simultaneously transmit and receive on the same channel using standard WiFi 802.11ac PHYs are presented and achieves close to the theoretical doubling of throughput in all practical deployment scenarios.Abstract:
This paper presents the design and implementation of the first in-band full duplex WiFi radios that can simultaneously transmit and receive on the same channel using standard WiFi 802.11ac PHYs and achieves close to the theoretical doubling of throughput in all practical deployment scenarios. Our design uses a single antenna for simultaneous TX/RX (i.e., the same resources as a standard half duplex system). We also propose novel analog and digital cancellation techniques that cancel the self interference to the receiver noise floor, and therefore ensure that there is no degradation to the received signal. We prototype our design by building our own analog circuit boards and integrating them with a fully WiFi-PHY compatible software radio implementation. We show experimentally that our design works robustly in noisy indoor environments, and provides close to the expected theoretical doubling of throughput in practice.read more

Achievable Transmission Rates and Self-Interference Channel Estimation in Hybrid Full-Duplex/Half-Duplex MIMO Relaying
TL;DR: It is shown that the estimation of the self-interference channel within the relay should be performed when the source is not transmitting anything while also the source should be allowed to transmit alone to avoid making the first hop a bottleneck.

A Digital-Domain Controlled Nonlinear RF Interference Cancellation Scheme for Co-Site Wideband Radios
TL;DR: A digital-domain reconstruction based radio-frequency (RF) interference cancellation scheme is proposed to cancel the nonlinear wideband self-interference (SI) signal in co-site radio systems and validated that the proposed scheme has a superior interference cancellation performance for non linear wideband SI.

Transceiver and method for reducing a self-interference of a transceiver
TL;DR: In this article, a transceiver (1000) is proposed for interference cancellation on a receiving signal in a radio frequency domain and in a digital domain, where the transceiver comprises an antenna arrangement (100) configured for interfacing a wireless transmission channel and comprising an interface (110) for receiving a sending signal (202) and an interface for providing receiving signal (106).

Optimal Transmission Using a Self-Sustained Relay in a Full-Duplex MIMO System
Rafia Malik,Mai Vu +1 more
TL;DR: In this paper, a primal-dual algorithm was proposed to jointly optimize power splitting at the relay and precoding design for both the source and relay transmissions in a full-duplex MIMO relay channel where the self-sustained relay harvested energy from both source transmit signal and self-interference signal to decode and forward source information to a destination.

Convex Optimization
Stephen Boyd,Lieven Vandenberghe +1 more
TL;DR: In this article, the focus is on recognizing convex optimization problems and then finding the most appropriate technique for solving them, and a comprehensive introduction to the subject is given. But the focus of this book is not on the optimization problem itself, but on the problem of finding the appropriate technique to solve it.
