摘要

We propose a differential-detection receiver architecture and a novel recursive algorithm for electronic polarization tracking in polarization-division-multiplexed differential quadrature-phase-shift-keying (PDM-DQPSK) systems. Simulation results demonstrate that the proposed system approaches the performance of coherent-detection-based PDM-DQPSK systems.
