摘要：

In this tutorial paper, we compare performance of several classes of forward error correction schemes suitable for advanced optical transmission. The first class is based on the concatenation of two RS codes. The second class is based on turbo product codes with BCH codes as component codes. The third class is based on low-density parity-check (LDPC) codes that have attracted much attention over the past decade. The fourth class of codes to be presented is generalization of both turbo product and LDPC codes, known as generalized LDPC (GDLPC) codes. To increase the coding gain while keeping the codeword length reasonable low, the class of nonbinary LDPC codes is introduced. A sophisticated simulator that models all major transmission impairments is used to assess the performance of the error correction schemes.
