Title:
MULTIBAND SIGNAL PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/138880
Kind Code:
A1
Abstract:
Disclosed is a multiband signal processing method, comprising: forming a co-feedback signal group from signals having bands near to each other in a multiband signal; performing co-feedback processing for each co-feedback signal group; acquiring a multiband signal in each co-feedback signal group by utilizing a low speed ADC, and performing multiple interpolation processing on the co-feedback signal obtained by the acquisition, and on an original training sequence; and performing pre-distortion processing for the co-feedback signal using a digital pre-distortion (DPD) model. During processing, an autocorrelating U matrix is filtered according to multi-stage intermodulation information, and intermodulation and cross modulation information forming a U matrix distal end sideband is filtered, thus reducing hardware resources consumed by the multiband pre-distortion.
