  • DUAL-POLARIZATION -JOINT NOISE PROCESSING METHOD AND DEVICE
    Publication number: 20240146427
    Abstract: The present application relates to a dual-polarization-joint noise processing method and device. The present application compensates the discrete spectral coefficient noise on the X polarization state with noise information carried by the discrete spectral eigenvalue on the X, Y polarization states, and a correlation coefficient between the discrete spectral eigenvalue and the discrete spectral coefficient on the X polarization state. Similarly, compensating the discrete spectral coefficient noise on the Y polarization state with noise information carried by the discrete spectral eigenvalue on the X, Y polarization states, and a correlation coefficient between the discrete spectral eigenvalue and the discrete spectral coefficient on the Y polarization state.
