I asked a bout how can download data of Impulse radio-ultrawideband (IR-UWB) with coherent optical orthogonal frequency division multiplexing (CO-OFDM).
For additional information helping you to build your system please follow the paper in the link:https://optiwave.com/applications/coherent-optical-ofdm-2/
A generic CO-OFDM system includes five basic functional blocks: OFDM transmitter, RF to optical (RTO) up-converter, optical link, optical to RF (OTR) down-converter, and OFDM receiver.
You need only to substitute the OFDM radio system with your IR-UWB radio frequency system.
