Abstract
Official abstract text for this publication.
Provided is a method in which a Digital Pre-Distorter (DPD) performs digital pre-distortion on a received In-phase (I) signal, a received Quadrature-phase (Q) signal, a feedback I signal, and a feedback Q signal; a mixer mixes a signal output from the DPD with a frequency signal output from an oscillator; each of n phase shifters phase-shifts a signal output from the mixer according to a preset beamforming pattern; each of n Power Amplifiers (PAs) amplifies a signal output from an associated phase shifter according to a gain, the PAs connected to the associated phase shifter on a one-to-one basis; each of n envelope detectors detects an envelope signal from a signal output from an associated PA, the envelope detector connected to the associated PA on a one-to-one basis; and a control unit determines whether the n PAs operate normally, using the envelope signals output from the n envelope detectors.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for compensating for distortion of a transmitter array in a radio communication system, the apparatus comprising: a Digital Pre-Distorter (DPD) configured to perform a digital pre-distortion operation on a received In-phase (I) signal, a received Quadrature-phase (Q) signal, a feedback I signal, and a feedback Q signal; an oscillator configured to oscillate a preset frequency signal; a mixer configured to mix a signal output from the DPD wit…
