Title:
DATA SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/177758
Kind Code:
A1
Abstract:
The present disclosure provides a data signal processing method and apparatus. The processing method comprises: determining inputted values of each stage of butterfly operations in a fast transform algorithm between a time domain and a frequency domain according to sequence values of sampled inputted signals, the quantity of the inputted values of each stage of butterfly operations being equal to a cardinal number of the fast transform algorithm between a the time domain and the frequency domain; decomposing each stage of butterfly operations into multiple stages of cascaded operations according to the inputted values of each stage of butterfly operations; using outputted values obtained after multiple stages of cascaded operations are performed on each stage of butterfly operations, as inputted values of a next stage of butterfly operations; and obtaining outputted sampled signals corresponding to the sampled inputted signals according to outputted values of a last stage of butterfly operations.
