1. A method for detecting interference, comprising:
receiving a signal;
obtaining a power value of the signal as a first power;
filtering the signal to obtain a filtered signal;
obtaining a power value of the filtered signal as a second power; and
determining whether a frequency channel where the signal is located is an interference frequency channel or a non-interference frequency channel based on a comparison result of a ratio of the first power to the second power and a preset threshold.
