Abstract :
We present a hybrid modulation format recognition method combining Stokes-space analysis/higher-order-statistics, robust in lower OSNR conditions that successfully identifies OOK/BPSK/QPSK/16-QAM. The new architecture´s blind demodulation performance is compared to our previous one using experimental 1056km transmission data at 16/32Gbaud.
