  • Patent number: 9693245
    Abstract: Disclosed in the present disclosure are a method and system for measuring interference signals in carrier signals. The method comprises: receiving multiple valid samples of the carrier signals; based on the multiple valid samples of the carrier signals, gaining value of constant part and mean square error of zero mean part in the interference signals through iterative calculation; calculating the total power value of the interference signals. Since considering the constant part in the interference signals, the measurement method is suitable in the case that the interference signals in the carrier signals is non-zero mean value, and the obtained measurement result of the interference signals will be more accurate than the result through the existing method.
