    • A method of estimation of harmonic distortion level for a radio receiver operative in a cellular communication system enabled to receive signals from transmitters of one or more cells is disclosed. The method comprises measuring, within a bandwidth of operation, a total received signal power; measuring, within the bandwidth of operation, a received signal power of signals received from the one or more cells, respectively; and estimating a level of harmonic receiver distortions by: determining whether a fraction of the total received signal power and a theoretical noise floor is below or above a first threshold; or determining whether a remaining part of the total received signal power, said remaining part not including said fraction, is above or below a second threshold. A such radio receiver, and a computer program for implementing the method are also disclosed.
