Abstract:
We proposed a clock recovery algorithm for multiple symbol rates and a phase-domain carrier recovery for multiple modulation formats. We demonstrated a FPGA-based real-time coherent receiver that supports BPSK, QPSK and 16QAM with different symbol rates, achieving a line bit rate from 2.5Gbps to 100Gbps.
