A MIMO precoder, a method and a computer program product are disclosed. The MIMO precoder comprises: a first plurality of digital signal inputs, each operable to receive a corresponding one of a first plurality of digital data streams containing data for transmission to reception equipment; processing logic operable generate a second plurality of precoded digital data streams by performing a digital beamforming function and a digital predistortion function on the first plurality of digital data streams; and a second plurality of signal outputs, each operable to output a corresponding one of the second plurality of precoded digital data streams to a corresponding transceiver for transmission to the reception equipment. In this way, the digital data streams can be precoded to perform both digital beam-forming and digital pre-distortion jointly on the digital data streams so that they can be optimized simultaneously within the processing logic and then each precoded digital data stream provided directly to the transceiver chain which drives an associated antenna element. This provides a scalable arrangement where the precoding can be performed independently of the transceiver chain. This provides for a flexible architecture where the precoding is decoupled from the operation of the transceiver chain and the antenna array, which enables these units to be spatially separated if required. Also, by performing digital pre-distortion, the RF amplifiers can be operated in the non-linear, high efficiency operation region.
