Title:
DPD SYSTEM AND IMPLEMENTATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/091929
Kind Code:
A1
Abstract:
Provided are a DPD system and an implementation method therefor. The system comprises a DPD module for receiving a baseband signal and performing DPD processing on the baseband signal to generate a DPD signal; a baseband signal processing module for receiving and processing the baseband signal into a target baseband signal, wherein the target baseband signal is a target baseband signal subjected to narrow-band filtering; a DPD signal processing module for receiving and processing the DPD signal into a target DPD signal; a combiner for combining the target baseband signal and the target DPD signal to generate a combined signal; and a signal output processing module for outputting the combined signal. In the embodiments of the present invention, a baseband signal and a DPD signal are respectively processed, so that the signal-to-noise ratio of a baseband signal part is improved before combination, transmission noise and transmission stray of a combined signal after the combination are reduced, and thus a higher transmission power can be adopted to transmit an output signal under the same stray index requirement for radio-frequency transmission.
