Abstract: An apparatus includes an estimation circuitry configured to receive a first set of one or more digital signals of transmitters of a communication system, and capture a set of one or more radio frequency signals that have been generated from the first set of digital signals The set of radio frequency signals being input of an antenna system of the communication system. Based on the first set of digital signals and the corresponding set of radio frequency signals, a set of weights related to a distortion effect caused by the generation of the radio frequency signals is derived. A received second set of digital signals is weighted using the set of weights, resulting in filtered signals. Using the filtered signals, a correction signal indicative of an interference caused by transmission of the second set of digital signals at a receiver of the communication system is estimated.

Abstract: The present subject matter relates to an apparatus for a communication system. The communication system comprises transmitters being configured to operate in multiple transmission frequency bands. The apparatus comprises means being configured for: capturing a set of over-the-air signals at distinct frequency bands of the multiple transmission frequency bands; aligning in time the set of signals using delays between the set of signals and a received signal at a selected receiver of the communication system; combining the set of aligned signals to generate a composite signal; and estimating an interference signal that is caused by the set of signals at the selected receiver by weighting the composite signal using a set of one or more calibrated parameters for the estimation.

Abstract: The present subject matter relates to a method comprising: receiving a set of signals from transmitters of a communication system, the communication system having a system configuration. A first and second set of machine learned parameters may be provided in accordance with the system configuration. The received signals may be weighted using the first set of machine learned parameters. The weighted signals may be combined to generate a composite signal. The composite signal may be weighted with the second set of machine learned parameters in order to estimate an interference signal that is caused by the set of signals at a receiver of the communication system.
