Abstract
The proposed maximum likelihood sequence estimation (MLSE) receiver to mitigate polarization mode dispersion (PMD) impairment on phase-shift keying incorporates polarization diversity receiving and joint symbol processing by employing another delay interferometer (DI) using cross polarization interference together with a traditional DI. Applied to an 80-Gbit/s DQPSK demonstration system, the joint-symbol MLSE receiver shows better performance.
