Real-Time FPGA-Based Intradyne Coherent Receiver for 40 Gbit/s Polarization-Multiplexed 16-QAM
Coherent communications Optical communications
2015/5/25
Real-time detection of a 40 Gbit/s polarization-multiplexed square 16-QAM signal is demonstrated in an FPGA-based intradyne coherent receiver processing 100% of data. A minimum BER of 3.3×10 -5 is ach...
Real-time FPGA-based Coherent Optical Receiver for 1 Gsymbol/s, 64 QAM Transmission
Coherent communications Fiber optics communications
2015/5/25
We demonstrated the first time real-time FPGA-based coherent optical receiver for a 64 QAM transmission. Error free performance (BER < 1x10 -12 ) was achieved under a back-to-back condition and the BE...
FPGA Verification of a Single QC-LDPC Code for 100 Gb/s Optical Systems without Error Floor down to BER of 10 -15
Fiber optics communications Optical communications
