Abstract

A novel forward error control system for long haul optical communication systems based on low-density parity check codes and iterative decoding is proposed. Codes are constructed using mutually orthogonal Latin rectangles or integer lattice, and the coding system performance is improved by eliminating short cycles in a graph employed in iterative decoding. As opposed to the common practice of considering the performance of error controlling schemes using the AWGN assumption, we consider the performance of high-girth codes in the presence of ASE noise, pulse distortion due to fiber nonlinearities, residual dispersion, crosstalk effects, intersymbol-interference, etc.
