Abstract

A method for use in receiving a selected subcarrier of a Coherent Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) signal employs an adaptive Fractionally-Spaced Time-Domain Equalizer (FS-TDE) (204). The FS-TDE (204) has a plurality of configurable tap coefficients, which are configured according to the method such that the FS-TDE is adapted to simultaneously demultiplex and equalize the selected subcarrier. The CO-OFDM signal (102, 104) is processed using the FS- TDE (204) to generate and output a demultiplexed and equalized selected subcarrier signal. The use of a suitable adaptive FS-TDE enables a number of previously distinct signal processing functions to be combined into a single, simplified, signal processing element. In particular, the functions of a mixer, a Discrete Fourier Transform (DFT), and an equalizer for linear distortions, such as chromatic dispersion and Polarization Mode Dispersion (PMD), may be combined into a single demultiplexing and equalizing FS-TDE.
