Abstract
In this project, tThe statistical properties of
nonlinear phase noise together witbwith linear phase
noise are first investigated for small number of fiber
spans. The exact error probability of DPSK signals with
nonlinear phase noise will beis derived and measured.
The measurement can confirm the validity of the
theoretical models and its usage as a means to optimize
the system design.
The joint probability density of received electric
field with nonlinear phase noise, including both
amplitude and phase, will be investigatedis derived the
first time. .
Correlated with received intensity, nonlinear phase
noise can be compensated by combining with a scale
version of the received intensity. A linear compensator
will be implemented in this project. Based on the
probability density of the received signal, the optimal
detector (or the optimal compensator) to minimize the
error probability of a signal with nonlinear phase noise
will also be derived analytically.
