Abstract
The present invention, which relates to a multi-path communication device for sharing a feedback path for digital pre-distortion, includes: a DPD processing unit configured to output a plurality of pre-distorted signals by respectively pre-distorting a plurality of input signals, to output an ncontrol signal when an ninput signal is input, and to output an npre-distorted signal using an nfeedback signal input in response to the ncontrol signal; a power amplifying unit configured to amplify each of the plurality of pre-distorted signals and output a plurality of amplified signals; a signal combining unit configured to combine some of each of the plurality of amplified signals and output combined feedback signal; and a signal selection unit configured to select and output only the nfeedback signal from the combined feedback signal according to the input ncontrol signal, thereby preventing an increase in the size of a device and manufacturing cost thereof caused by a plurality of DPD feedback paths.
