Example Embodiment
[0046] Embodiment 1: A fiber nonlinear equalization method based on the KNN algorithm without data assistance, the device used is as attached figure 1 As shown, the signal from the transmitting end is transmitted through the long-distance optical fiber, and then received by the receiver. The received optical signal is converted into an electrical signal. After the carrier phase is restored, it enters the nonlinear equalizer (KNN detector) of this embodiment. Perform fiber nonlinear equalization.
[0047] The fiber nonlinear equalization method is: divide the data into training model and test model, use density function to extract less noisy data, label them in the training model, as training samples, and apply KNN algorithm to use more in the test model Noise classifies data.
[0048] See attached image 3 , Specifically including the following steps:
[0049] (a) Training model
[0050] This part includes three steps, extracting data by density, marking data with demodulation and
