This adjustment ensures that the phase estimate follows the trajectory of the
physical phase and cycle slips are avoided [15].
3.4 PERFORMANCE EVALUATION OF THE DIGITAL
COHERENT RECEIVER
This section deals with evaluation of basic characteristics of the digital coherent
receiver. After showing the optical circuit for the homodyne receiver comprising
phase and polarization diversities, we discuss the receiver sensitivity limit, the
polarization dependence of the receiver sensitivity, and the phase noise tolerance
