The system uses photonic crystal fibers as the channel transmission medium and uses segmented filtering algorithms for demodulation and decoding. In the system design, a feedback adjustment method is used to compensate for fiber loss, improving the reliability and stability of the system; MATLAB simulation tools are used to analyze system performance and simulate experiments, confirming the demodulation effect and practicality of the system. Experimental results show that the system has the advantages of fast demodulation and high precision, and can be applied to high-speed optical communication and fiber-optic sensing.Keywords: PZ-DPSK optical signal, demodulation and decoding system, photonic crystal fiber, segmented filtering algorithm.
