ABSTRACT
We review main signal processing techniques for mitigation of physi-
cal impairments in optical systems and discuss some of the important
issues in their design and application in the optical domain.
1. INTRODUCTION
Physical impairments in the optical fiber, in particular, the chromatic
dispersion, fiber nonlinearities, polarization effects, and amplified spon-
taneous emission noise from the amplifiers, all interact limiting the
data rates and/or transmission distances. Electronic domain (post-
detection) techniques offer effective means for mitigating effects of
these impairments, an observation made more than a decade ago [10].
Successful demonstrations of the effectiveness of these techniques for
high-speed optical communications have appeared more recently, and
promising results in this area attracted attention to the field (see e.g.
[2] and the references therein). The solutions based on signal process-
