Abstract: An apparatus of a wireless device can include baseband processing circuitry configured to generate a digitized downconverted signal based on a received radio frequency (RF) signal. The apparatus can also include estimation circuitry configured to detect a blocker signal in the downconverted signal, the blocker signal having power that exceeds a pre-determined threshold, and map the detected blocker signal to a plurality of harmonic frequencies associated with two or more carrier frequencies. The apparatus can include reference signal generation circuitry configured to generate a reference signal based on the plurality of harmonic frequencies and the received RF signal. The apparatus can include cancellation circuitry configured to apply a pre-processed reference signal (based on the reference signal) to the digitized downconverted signal to remove distortion associated with the detected blocker signal. The digitized downconverted signal is a baseband signal or an intermediate frequency (IF) signal.

Abstract: Examples provide a device, an apparatus, a method, a computer program, a receiver, a mobile terminal and a base station. An interference detection device (10) is configured to generate an auxiliary interference signal for a multi-carrier receive signal. The device (10) comprises a generator (12) configured to generate a plurality of oscillator signals. The plurality of oscillator signals comprises at least a first oscillator signal with a first local oscillator frequency. The plurality of oscillator signals further comprises a second oscillator signal with a second local oscillator frequency. The device (10) further comprises a plurality of subsequent mixers. A first mixer (14) is configured to mix the multi-carrier receive signal with the first oscillator signal to output a first mixed signal. A second mixer (16) is configured to mix a second mixed signal with the second oscillator signal to output the auxiliary interference signal.
