Example embodiments provide a method for compensating transmitter distortions. The compensation can be performed with tapered antenna elements. The method comprises determining a first subset of antennas of an antenna array, wherein the first subset of antennas operate without a power headroom in relation to one or more thresholds; determining a second subset of antennas of the antenna array, wherein the second subset of antennas comprise one or more antennas that operate with a power headroom in relation to the one or more thresholds; calculating compensation signals for distortions of wanted signals to be transmitted with the first subset of antennas to one or more user devices; combining the compensation signals with wanted signals to be transmitted with the second subset of antennas to the one or more user devices; and transmitting, with the second subset of antennas, the compensation signals combined with the wanted signals. An apparatus, a method, and a computer program are disclosed.
