The invention provides a high-order continuous polarization modulation method of improving spectral efficiency. The specific steps are as follows: step one, sending the high-order continuous polarization modulation for original data transmission information and particularly achieving the continuity of polarization states through the continuous variation of amplitude ratio under the condition of constant phase difference; step two, performing the demodulation of high-order continuous polarization signals at the receiving end through the Stokes parameter extraction method.
