Reliability and validity are two performance indicators digital communication systems. However, in digital communication systems, which are often contradictory, of contemporary bands are getting increasingly nervous, on the premise of guaranteed reliability validity is the eternal theme of communication as possible. Optical communication system, receiver at the time of phase retrieval must be found to overcome the phase ambiguity, therefore, often using differential modulation (DQPSK). However, differential modulation leads to signal error rate doubled, an extra signal-to-noise ratio price. Iterative differential demodulation and decoding schemes are analyzed, optimization of LDPC coding and differential modulation as a whole. Simulation results show that the programme phase fuzzy can compensate the price differential can be overcome, and enhances the reliabi
