Abstract
A linearization device (380) is disclosed, which is configured to determine pre-distortion parameters associated with a plurality of non-linear amplifiers (331, 332, 333, 334), each associated with a non-linear amplifier characteristic. The linearization device comprises determination circuitry (383), a first port (381) and a second port (382). The first port is configured to receive a plurality of channel coefficients indicative of channel characteristics of a plurality of communication paths (391, 392, 393, 394) between the plurality of non-linear amplifiers and a transmit observation receiver (370). The second port is configured to receive, from the transmit observation receiver, a sum of transmission signals generated by the plurality of non-linear amplifiers and transferred over the plurality of communication paths. The determination circuitry is configured to determine the pre-distortion parameters based on the received plurality of channel coefficients, the received sum of transmission signals, and a model of the non-linear amplifier characteristics of the non-linear amplifiers. Corresponding arrangement, wireless transmitter node, cloud based server node, method and computer program product are also disclosed.
