Interference detection device, interference detection apparatus, interference detection method, computer program, receiver, mobile terminal and base station

An interference detection method for generating an auxiliary interference signal for a multi-carrier receive signal, comprising

• generating a plurality of oscillator signals, the plurality of oscillator signals comprising at least a first oscillator signal with a first local oscillator frequency, and a second oscillator signal with a second local oscillator frequency;
• first mixing the multicarrier receive signal with the first oscillator signal to output a first mixed signal,
• second mixing of a second mixed signal with the second oscillator signal to output the auxiliary interference signal,
• wherein the plurality of oscillator signals comprises one or more additional oscillator signals having one or more additional local oscillator frequencies being adjusted to one or more additional carrier frequencies of the multi-carrier receive signal, the interference detection method further comprising one or more intermediate mixings between the first mixing and the second mixing to provide the second mixed signal.
