Abstract:
We demonstrate the first GPU platform to softwarize flexible-rate coherent DSP; it can receive 2-, 4-, 8- and 16-PSK frames by changing the coding description. Receiver sensitivity is measured in real-time for Gbaud-class rate frames, with LDPC thresholds of −50.5, −46.5, −40.5 and −33.5dBm, respectively.
