We propose a new modulation format recognition method for optical links employing OOK, M-PSK, M-PAM, and M-QAM modulation formats. The method combines the Stokes space analysis and higher order statistics as a part of a universal digital coherent receiver. Experimental investigation demonstrates successful format recognition of single-carrier optical signals modulated at 31.5 GBd with OOK, BPSK, QPSK,...
We present a novel DSP architecture that identifies multi-gigabit photonic assisted RF signals with minimum prior knowledge of the received signal. Experimental investigation demonstrates successful identification of optically generated RF carriers modulated with 8 Gbaud BPSK/QPSK/8-QAM/16-QAM, after wireless transmission over 1 m in the V-band.
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.
