Abstract :
This paper shows that carrier phase locking and signal pre-distortion reduce linear/nonlinear crosstalk for a signal with spectrum overlap. Experimental results show that the penalty caused by four-wave-mixing crosstalk is successfully suppressed for a signal with a 1-bit/s/Hz spectral efficiency.
