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.
