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

Improving the Performance of Spatial Modulation Full-Duplex Relaying System With Hardware Impairment Using Transmit Antenna Selection
TL;DR: It is recommended to apply TAS to improve the performance of SM-FDR systems when both HI and RSI exist in reality and the system performance is significantly enhanced, i.e. the SER is reduced, when TAS is applied.

Relaying via Cooperative Jamming in Covert Wireless Communications
TL;DR: This work finds the optimal detection threshold of Willie's detector and his minimum detection error probability and derives the expected value of this error probability, establishing Willies detection performance from the perspective of the covert communication pair, and derives a closed-form expression for the optimal transmit power of covert communication.

Transceiver Design to Maximize Sum Secrecy Rate in Full Duplex SWIPT Systems.
TL;DR: In this paper, the authors considered secrecy simultaneous wireless information and power transfer (SWIPT) in full duplex systems, where a FD-BS is designed to transmit data to one downlink user and concurrently receive data from one uplink user, while one idle user harvests the radiofrequency (RF) signals energy to extend its lifetime.

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.
