Viterbi Equalizer for Chromatic Dispersion and PMD Mitigation in DPSK and DQPSK Systems at 10 Gb/s

We study the Viterbi equalizers for chromatic dispersion and PMD mitigation in 10 Gb/s NRZ-DPSK and NRZ-DQPSK systems. Monte Carlo simulations are used to assess the performance of the Viterbi equalizers.
