Title:
COMPRESSED SAMPLING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/134549
Kind Code:
A1
Abstract:
Disclosed is a sampling apparatus, comprising: a mixing unit for randomly demodulating an acquired analogue signal respectively by K parallel mixers, so as to obtain K demodulation signals, wherein K is a natural number and K > 1; an integration unit for integrating the K demodulation signals respectively by K integrators, so as to obtain K integration numerical values; and a sampling unit for respectively sampling the K integration numerical values, so as to obtain K compressed sampling values. Also disclosed is a compressed sampling method. By means of the present invention, the complexity of integration calculation in a sampling apparatus is effectively reduced, and accordingly the calculation complexity of the sampling apparatus and the complexity of hardware implementation of the sampling apparatus are reduced, and the calculation speed of the sampling apparatus is increased.
