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

Link Regime and Power Savings of Decode-Forward Relaying in Fading Channels
TL;DR: This paper designs a composite DF relaying strategy that achieves the same rate as block Markov DF but with less required relay power, and derives the outage probability of the composite relaying scheme, which adapts the signaling to the link regime.

MIMO Full Duplex Radios with Deep Learning.
TL;DR: A novel design for self-interference (SI) cancellation in multiple-input multiple-output (MIMO) full duplex radios by using a cascaded neural network structure and shows that using a one layer Rectified Linear unit (ReLU) neural network to solve the SISO SI problem is theoretically optimal.

Secure Transmission and Self-Energy Recycling for Wireless-Powered Relay Systems with Partial Eavesdropper Channel State Information.
TL;DR: In this article, a two-phase protocol is proposed, in which the relay operates in full-duplex (FD) mode to achieve simultaneous wireless power and information transmission with imperfect eavesdropper channel state information (ECSI).

Impact of Received Signal on Self-interference Channel Estimation and Achievable Rates in In-band Full-duplex Transceivers
TL;DR: It is shown that, even though a substantial increase in the parameter sample size is required if there is no calibration period, the achievable rates are still comparable for the two scenarios.

Low-Complexity Nonlinear Self-Interference Cancellation for Full-Duplex Radios
TL;DR: This paper proposes the pre-calibration method that linearizes the transmitter, and applies only linear SIC, and results confirm that the proposed SIC method shows 43 dB cancellation performance while the existing method shows only 18 dB in fast fading channels.

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.
