Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0046] At present, when signal sampling is performed through compressed sensing technology, the application data corresponding to the signal is first trained to learn the internal mode of the application data, so as to obtain the real number sampling matrix related to the application data, and then use the real number sampling matrix to analyze the application data The corresponding target signal is sampled. Since the complexity and power consumption o...

Abstract

The embodiment of the invention provides a signal sampling method, a signal sampling system and a signal sampling device. The signal sampling method comprises the following steps: according to application data corresponding to a target signal, obtaining a real matrix psi with m rows and n columns and associated with the application data, wherein m and n are integers greater than or equal to 1; according to psi, obtaining a Boolean sampling matrix meeting the condition (1); sampling a target signal and obtaining a sampling value. According to the technical scheme of the invention, during the signal sampling process, the complexity and the power consumption of the hardware required for signal sampling based on the data-associated Boolean sampling matrix can be reduced.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a signal sampling method, a signal sampling system and a signal sampling device. Background technique [0002] The traditional signal processing process can include four parts: sampling, compression, storage / transmission and decompression. In the sampling process, the original signal is first collected according to the Nyquist sampling theorem, and then the collected data is compressed. In the compression process, the collected data is firstly transformed, and then a small number of coefficients with large absolute values ​​are compressed and coded, and other coefficients that are zero or close to zero are discarded. Among them, most of the data obtained by sampling are discarded in the compression process. [0003] In recent years, a new signal acquisition technology has been proposed, that is, Compressive Sensing technology (Compressive Sensing), which uses the sparseness of th...
