Patent attributes
A method, apparatus and receiver for detecting intermodulation distortion (IMD) affecting a received signal in a wireless receiver are provided. One method includes determining a measurement indicative of IMD based on at least one transmit signal. When the measurement indicative of IMD exceeds a first pre-determined level, at least one sample of an amplitude of a signal output by the wireless receiver is collected in a first data set. When the measurement indicative of intermodulation distortion does not exceed a second pre-determined level, the second predetermined level being less than the first predetermined level, at least one sample of an amplitude of the signal output by the wireless receiver is collected in a second data set. A comparison is performed based on data of the first data set and on data of the second data set to determine a measure of IMD.
