Low-density parity check codes for long-haul optical communication systems

A forward error correction (FEC) scheme was presented based on low density parity check codes (LDPC). A significant coding gain of LDPC with respect to the state-of-art FEC schemes employed in optical communication systems was demonstrated. A construction based on balanced incomplete block designs (BIBD) was proposed. It was demonstrated that good codes could be generated without using random interleavers or random sparse parity check matrices.
