Research on Efficiency Improvement Strategy of Optical Fiber Signal Transmission Based on Fourier Transform

Abstract

With the continuous development of society, optical fiber communication system has become a necessity in people’s life. Although the loopholes of the system are gradually improved, there are still many factors that affect the performance of the signal transmission in the actual transmission process. Compared with the traditional Fourier transform, there are some new transforms, such as fractional Fourier transform and DFT-S. These new transformations can observe, analyze and process signals more completely and concretely, Through which the signal can be transformed into the domain and more information of the optical fiber signal can be obtained.
