Real-Time Digital Signal Processing Techniques with Optical Transceiver Prototype for Highcapacity Coherent FSO Communication
We present digital coherent DSP techniques for a several-GBaud FPGA-based FSO optical transceiver prototype accommodating Doppler shift and large propagation loss, and review virtual optical channels carrying multiple users' signals via subcarrier multiplexing.
