Abstract

The invention discloses a DSSS signal identification method, apparatus and device, and a computer readable storage medium, and the method comprises the steps: obtaining the signal edge of a to-be-identified signal, enabling the whole to-be-identified signal not to be subjected to high-speed sampling, and avoiding the use of a high-speed ADC; by acquiring the time interval of edge hopping of the to-be-identified signal, further reducing the amount of data required to be acquired by the single-chip microcomputer; determining the start and stop positions of the DSSS signal according to the time interval of edge hopping so as to complete identification of the DSSS signal, so that the operation time of the CPU of the single-chip microcomputer in the DSSS signal identification process is reduced, identification of the DSSS signal can be efficiently completed without an ADC of the single-chip microcomputer or without high performance of the CPU, and the equipment performance requirement of the single-chip microcomputer in the DSSS signal identification process is reduced.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a DSSS signal identification method, device, equipment and computer-readable storage medium. Background technique [0002] Direct Sequence Spread Spectrum (DSSS, Direct Sequence Spread Spectrum) technology is to encode one bit of data into a multi-bit sequence, called a chip; reasonable selection of chips helps to improve processing gain and enhance the anti-interference ability of the channel , in order to cope with noisy wireless network environments. [0003] The existing single-chip microcomputer recognizes the DSSS signal mainly by using an analog-to-digital converter (ADC, analog to digital converter) to perform intensive sampling. However, in order to ensure that the sampled digital signal can completely retain the information in the original signal, it is necessary to use an ADC with a high sampling rate to achieve it; Finally, it is necessary to disti...
