Abstract
We investigate the potential of optical n-stage FIR filter
architectures for PMD compensation (PMDC) based on frequency-dependent
optical power monitoring. The measurement information is used to partially
estimate the channel's Jones matrix U (omega), and the filter parameters
are adjusted based on solving a nonlinear least-squares problem which
mimics the approximate inversion of U (omega) by the filter. Numerical
studies of the optimization method and outage probability simulations show
the robustness and scalability of the proposed concept.
