Self-Interference Cancellation: Full-Duplex Revolution



Self-Interference Cancellation: Full-Duplex Revolution

Thursday, April 18, 2019 14:00 -15:00 EDT

 

ABOUT

Self-interference cancellation invalidates a long-held fundamental assumption in wireless network design that radios can only operate in half duplex mode on the same channel. Beyond enabling true in-band full duplex, which effectively doubles spectral efficiency, self-interference cancellation tremendously simplifies spectrum management. It enables future networks to leverage fragmented spectrum, a pressing global issue that will continue to worsen as the spectrum gets more crowded. Self-interference cancellation offers a sustainable path toward denser heterogeneous networks and can be utilized in wireless communication systems in multiple ways, including increased link capacity, spectrum virtualization, any-division duplexing (ADD), novel relay solutions, and enhanced interference coordination.

At the most basic level, self-interference cancellation replaces arcane solutions like passive RF filters, metal shielding, and physical isolation. Unlike filters that merely wall off a range of frequencies, self-interference cancellation directly attacks the interfering signal. Consequently, it can be used to eliminate interference between co-located radios, enable unprecedentedly aggressive frequency reuse, and generally facilitate spectrum sharing by doing away with guard bands and permitting total flexibility in frequency assignments. By virtue of its fundamental nature, self-interference cancellation will have a tremendous impact on the design of future networks.

The presentation will discuss the evolution of the technology since its roots at Stanford University, its applications, implementation challenges, and state-of-the-art performance based on dedicated integrated circuits (ICs) that have been developed to enable mass adoption of the technology. .

PRESENTER

  

Joel Brand is Vice President of Product Management for Kumu Networks, a startup that was spun out of Stanford University research on wireless Full-Duplex. For over 25 years Joel has actively participated in defining and building infrastructure solutions for the telecom and wireless industries. He previously held executive positions at ConteXtream (acquired by HP), Bytemobile (acquired by Citrix) and Ruckus Wireless (NYSE: RKUS and now part of Arris). Prior to his industry career, Joel was a communications officer in the Signal Corps of the Israeli Defense Force (IDF) where he pioneered some of the very early C3I applications to track friendly forces. Joel holds a B.Sc. and M.Sc. in Engineering from the Israeli Institute of Technology (the Technion) as well as MBA from National University in San Diego.
