Abstract
An apparatus, method and computer program is described comprising: obtaining time domain samples of a received radio frequency signal of a mobile communication system, wherein the radio frequency signal comprises a Physical Random Access Channel; determining an estimated power distribution for the time domain samples; determining a filtering threshold value at which a time domain sample is deemed to be due to interference, based on a defined probability level of the estimated power distribution; defining a filtering mask based on the time domain samples and the filtering threshold; and applying the filtering mask to the time domain samples to generate a filtered signal samples, wherein the filtering mask is configured to attenuate time domain samples that are above the filtering threshold.
