Paper Abstract

In order to overcome the defects of least squares (LS) estimator used to eliminate phase noise in the direct-detection (DD) optical orthogonal frequency division multiplexing (OOFDM) transmission system, we present an adaptive Least Mean Square (LMS) estimator which has the same computational complexity as LS estimator. The performance of the proposed estimator is evaluated in an experimental system with 2.5Gbits/s DD-OOFDM signal transmission over 100km standard single mode fiber (SSMF). The experimental results show that the performance of the system with LMS estimator is much better than that with LS estimator.
