Abstract :
We present a novel DSP architecture for coherent optical receivers that identifies time-domain hybrid modulation formats without any prior knowledge of the received signal. Experimental investigation demonstrates successful identification of 31.5GBaud TDHMF signals composed with BPSK/QPSK/8QAM/16QAM after 810km transmission.
