Photonic-Assisted Multipath Self-Interference Cancellation for Wideband MIMO Radio-Over-Fiber Transmission

To cancel the multipath self-interference at the receiver of a wideband in-band full-duplex (IBFD) multiple-input multiple-output (MIMO) radio-over-fiber (RoF) transmission system, a photonic-assisted approach is proposed and experimentally demonstrated. A multipath optical tunable delay line (MOTDL) module with a large adjusting arrangement and high tuning precision is designed to manipulate the ...
