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

Methods, systems, and computer readable media for mitigation of in-band interference of global positioning system (gps) signals
TL;DR: In this article, a deterministic phase control scheme was proposed to mitigate in-band interference of GPS signals using a pair of antennas, each receiving GPS signals that include both a desired signal component and a jammer signal component.

Impact of Directionality on Interference Mitigation in Full-Duplex Cellular Network
TL;DR: This paper considers two fundamental full-duplex architectures, two-node and three-node, in the context of cellular networks where the terminals employ directional antennas and provides a model which characterizes the way directional antennas manage the LI in order to passively suppress it.

Digitally Controlled Analog Wideband Interference Cancellation for In-Device Spectrum Sharing and Aggregation
TL;DR: The results suggest that the self-interference approach enables the simultaneous operation of thelicensed and unlicensed technologies in the adjacent spectrum within a single device, which, in turn, facilitates graceful spectrum sharing and bandwidth aggregation between the licensed and un licensed technologies.

On the sum rate of multi-user full-duplex massive MIMO systems
TL;DR: The Monte Carlo simulations show that the spectral efficiency of the multi-user full-duplex massive MIMO system is better than the half-duple (HD) counterpart when the number of receive/transmit antennas at the BS is large.

Improvement of Interference Suppression Performance Using Antenna Selection of Mobile Terminal for Full-Duplex $4\times4$ MIMO System
TL;DR: The authors propose a method to realize further interference suppression by applying the antenna selection method to the mobile terminal when performing eigen-beamforming, which is improved by about 3–5 dB compared with the conventional four element MIMO antenna.

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.
