TLDR
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

Equalization in amplify-forward full-duplex relay with direct link
TL;DR: This paper studies the outage performance of a full-duplex relaying network with amplify-and-forward scheme, and observes that the direct link provides a significant SNR gain, and including it is particularly important for self-interference combating at the receiver.

Frequency-Domain Hammerstein Self-Interference Canceller for In-Band Full-Duplex OFDM Systems
TL;DR: The proposed scheme achieves high SI cancellation as the time-domain PH based SI canceller with low computational cost and the convergence performance of the proposed scheme is faster than thetime-domain scheme.

A Linearization Technique for Self-Interference Cancellation in Full-Duplex Radios
TL;DR: It is shown that the self-interference channel in an indoor environment can be effectively modelled as $H(f)=C_0 + C_1f$ in the frequency domain, irrespective of the multipath environment, and linearization results in a simpler SI filter model in the digital domain due to dimensionality reduction of the channel parameters.

Investigation of full-duplex relay networks with imperfect channel estimation
TL;DR: Simulation results show the performance gains of the proposed algorithms versus per-node transmit power and relay-node number, and point out the significant effects of channel estimation errors and relay positioning on full-duplex cooperative.

Digital self-interference cancellation for Full-Duplex MIMO systems
TL;DR: An attractive hybrid method of mitigating the effects of the residual self-interference imposed by the signal propagation and analog/digital circuit non-idealities for Full-Duplex point-to-point multiple-input multiple-output (MIMO) systems is proposed.

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.
