Embodiment

[0055] figure 1 It is a schematic flowchart of a signal modulation pattern recognition method provided by an embodiment of the present invention. like figure 1 As shown, this embodiment provides a signal modulation pattern recognition method, including:

[0056] Step 101, obtaining the modulated signal to be identified;

[0057] In some embodiments, the modulation signal to be identified may be a digital signal or an analog signal. The acquired modulated signal to be identified can be

[0058] Step 102, generating a constellation diagram of the modulated signal to be identified;

[0059] In some embodiments, the digital signal is often represented on the complex plane to intuitively represent the signal and the relationship between the signals, and its expression is s l (t)=x(t)+jy(t). There are many ways to generate the signal constellation diagram, which may be generated by the methods in the prior art, or the following methods may be adopted. refer to figure 2 , ta...

Abstract

The invention relates to a signal modulation mode identification method and device, and is applied to the technical field of signal identification, and the method comprises the steps: obtaining a to-be-identified modulation signal; generating a constellation diagram of the modulation signal to be identified; converting the constellation diagram into a heat map; and based on a pre-trained modulation mode identification model, identifying the heat map to obtain a modulation mode of the modulation signal to be identified, the modulation mode identification model being a deep neural network model.

Description

technical field [0001] The invention relates to the technical field of signal identification, in particular to a signal modulation pattern identification method and equipment. Background technique [0002] With the proliferation of wireless devices and applications, the available electromagnetic radio spectrum is increasingly constrained. Therefore, using cognitive radio technology (Cogni.Radio, CR) to make full use of spectrum resources has received more and more attention. Modulation identification plays an important role in communication fields such as signal confirmation, interference identification, signal detection, and signal supervision. Modulation identification is an important application of cognitive radio, which is a communication between signal detection and signal demodulation. Technology, whose main task is to realize the intelligent reception and processing of signals. [0003] The traditional modulation recognition algorithm is usually a pattern recognitio...
