Abstract: Embodiments of the present invention provide a method for measuring co-channel signal interference, and a receiver, where the method includes precisely obtaining, by measuring temperature and by using a stored noise figure, a signal to noise ratio of a low power signal in a case in which there is no co-channel signal interference; obtaining, by controlling a transmit power, at least one group of receive powers and signal to noise ratios of the receiver, to obtain a signal to noise ratio of the low power signal during actual operation; and calculating an interference power according to a difference between the signal to noise ratio of the low power signal in a case in which there is no co-channel interference and the signal to noise ratio of the low power signal during actual operation.
