The invention provides an orthogonal intersection amplitude modulation signal phase ambiguity processing method and apparatus. The phase ambiguity processing method comprises steps of judging symbols in the X polarization state and the Y polarization state of a reception signal, and carrying out mapping to obtain first bit information, wherein the reception signal comprises multiple first signals; carrying out verification analysis of the first bit information to generate a first verification result; judging the first verification result to obtain a judgment result that whether phase ambiguity occurs to the reception signal or not; when the judgment result shows that phase ambiguity occurs to the reception signal, obtaining at least one first signal in the reception signal; subjecting the first signal to phase rotation to obtain a second signal; carrying out verification analysis of the second signal, storing the second signal if the verification result is normal, and enabling the second signal to be used for
