Wireless Full-Duplex: From Practice to Theory
Full-duplex is the ability of a node to transmit and receive simultaneously in the same band. Ideal wireless full-duplex communication can double the spectral efficiency compared to the traditional half-duplex communication. In this dissertation, we study the challenges in realizing full-duplex …

Optimal Routing and Power Allocation for Wireless Networks with Imperfect Full-Duplex Nodes
We study a wireless full-duplex network with imperfect interference cancellation and solve the routing and power allocation problem in this network. We use a model that focuses on the effects of full-duplex by including residual self-interference and one hop interference while other interfering …

Design and Implementation of an Analog High Power Broadband Self Interference Canceller for In Band Full Duplex
A Self-Interference Canceler is the principle component that allows for Simultaneous Transmit And Receive (STAR) of radio signal broadcasting. Previous research and designs by other groups have resulted in systems that either operate at high powers or are capable of cancellation over a wide …
