A base station (BS) for a wireless communication network serves two or more users (UEs). A first user is served by the base station to receive a first data signal from the base station, and a second user is served by the base station to receive a second data signal from the base station. The base station (BS) includes an antenna array for a wireless communication with the two or more users served by the base station, and a precoder connected to the antenna array. The precoder causes the antenna array to form a first transmit beam to transmit the first data signal to the first user, and to form a second transmit beam to transmit the second data signal to the second user, For transmitting the first data signal to the first user, the base station (BS) is configured to map data of the first data signal using a first transmit constellation, and for transmitting the second data signal to the second user, the base station (BS) is configured to map data of the second data signal using a second transmit constellation. The precoder is configured to apply a predistortion responsive to an estimated cross-talk between the first and second transmit beams.
