Abstract: A base station antenna and a base station including the base station antenna are provided. A base station antenna includes a transceiver array configured to output M signals, wherein M is an integer greater than 1; an antenna array including N antenna units, wherein N is an integer greater than M; a first-level signal allocating network configured to allocate first power to the M signals, and output P signals, wherein P is an integer greater than M; a signal synthesizing network including multiple signal synthesizers, wherein each of the multiple signal synthesizers utilizes two signals of the P signals to synthesize two output signals; and a second-level signal allocating network configured to allocate second power to signals output by the multiple signal synthesizers, and output N signals to the N antenna units.

Abstract: The disclosure discloses a digital predistortion (DPD) device and method. The DPD device comprises a predistorter configured to obtain a predistortion component from a digital baseband signal using a predistortion parameter and output the predistortion component; and a weighting unit configured to: obtain one or more weighted predistortion components by applying the predistortion component to one or more weighting coefficients, and obtain one or more predistortion correction signals by combining the digital baseband signal and the one or more weighted predistortion components, wherein the one or more weighting coefficients are determined based on the digital baseband signal, the predistortion component, and a synthesized signal in a main lobe direction obtained by combining radio frequency signals from a beamforming array.
