Example Embodiment
[0027] The following describes the spectrum sensing algorithm based on the variational modal decomposition of the present invention with reference to the accompanying drawings and specific embodiments: It should be noted that the examples used here are only for explaining the present invention, and the present invention is not limited thereto. Examples.
[0028] Step 1: First, generate the simulation signal BPSK.
[0029] The embodiment used in the present invention first generates a BPSK signal with a symbol rate R b =0.64MHz, carrier frequency f c =5.12MHz, sampling rate is f s =12.8MHz, the number of symbols is Len=200, the number of sampling points is N=Len*f s / R b .
[0030] Step 2: Determine the optimal number of modal decomposition K by analyzing the change curve of the characteristic parameter of the mean value of the instantaneous frequency of the component, and set an appropriate penalty factor a.
[0031] by Figure 4 It can be seen that when the number of decompositions i...
