| description | Forward error correction (FEC) technique has been widely used in wireless
communication and mass storage applications. In recent years, FEC has also become
very important to optical communication because of its powerful error correcting
ability. FEC codes provide performance gain by trading off coding gain with coding
redundancy and decoding complexity. For transmission bit rate of 10 Gb/s or higher,
coding redundancy of less than 25% is desired. Therefore, FEC schemes with
moderate coding redundancy and tolerable decoding complexity are desirable and
very important for high-speed long-haul optical systems. In this thesis, two FEC
augmentation schemes, namely wavelength interleaving and errors-and-erasures
decoding (E&ED), are proposed to improve the FEC performance of optical channels
subjected to polarization mode dispersion (PMD) and chromatic dispersion (CD).
Wavelength interleaving provides frequency diversity, hence reducing the effective
error burst length and improving FEC performance without requiring more coding
redundancy. In E&ED scheme, an erasure zone is used to collect highly unreliable
received symbols called erasure symbols. |
