Abstract
We present a novel LMS equalizer (FDE) for compensating polarization-mode dispersion (PMD) in polarization-multiplexed coherent fiber-optic systems based on the least mean squares (LMS) method with unstructured channel estimation (USE). It is a low-complexity algorithm compared to the traditional time-domain decision-directed LMS (DD-LMS) algorithm. Also, it converges faster and shows better bit error rate (BER) performance as compared to the frequency-domain block training-directed LMS (BTD-LMS) method.
