Abstract:

Future 5G wireless networks can benefit from the use of in-band full-duplex technologies that allow access to previously unused spectrum by suppressing consequential self-interference. While this interference mitigation is typically achieved using multiple techniques, existing RF cancellation schemes can limit a systems center frequency and instantaneous bandwidth. This paper introduces a unique RF canceller design that uses photonics and a vector modulator architecture to provide a high number of canceller taps with tunable time-delays, which allow the canceller to operate over wide bandwidths. A prototype of this concept was built, and successfully demonstrated the capability of tuning 20 canceller taps over 80 different delay locations that spanned 115 ns
