Abstract
Optical communication systems own transmission characteristics of low noise and high signal noise ratio, in this paper, construction methods for low density parity check (LDPC) codes for the system are proposed based on analyzing theories and characteristics of LDPC codes. Furthermore, some important conclusions useful for reducing the complexity of encoding/decoding algorithm of the LDPC code are obtained. Then the design and implementation of encoder/decoder can be more flexible.
