In the solution provided in the embodiment of the present application, the service logic layer 23 performs automatic monitoring of spectrum abnormality by using a carrier detection method based on multi-scale wavelet mode maximum fusion.
In a possible implementation manner, the service logic layer 23 is specifically configured to: carrying out power spectrum estimation on the collected intermediate frequency or radio frequency information in the system to be monitored; carrying out discrete dyadic wavelet transform on the estimated power spectrum to obtain transformed power spectrum information; dividing the transformed power spectrum information into multi-scale signals according to signal bandwidth and determining wavelet transformation orders, wherein the multi-scale signals comprise broadband signals, medium signals, narrowband signals and extremely narrow signals; performing multi-scale signal detection according to the mode maximum result of wavelet transformation with different orders, and estimating signal parameters according to the detection result; and monitoring the frequency spectrum according to the signal parameters to obtain frequency spectrum monitoring information, and monitoring abnormal frequency spectrum according to the frequency spectrum monitoring information.

Specifically, in the solution provided in the embodiment of the present application, the service logic layer 23 performs an automatic spectrum anomaly monitoring process by using a carrier detection method based on multi-scale wavelet mode maximum fusion as follows:

And estimating the signal power spectrum Sr (f) according to indexes such as sampling frequency fs and frequency resolution requirement delta f.
(2) Discrete dyadic wavelet transform of power spectrum
And (3) performing discrete dyadic wavelet transform on Sr (f), and performing discrete dyadic wavelet transform on Sr (f) by adopting a first-order differential of a quadratic spline function approximate Gaussian function as a wavelet mother function.
(3) Dividing the signal bandwidth and determining the corresponding wavelet transform order
Since the bandwidth span range of different signals is unknown in advance, the bandwidth range of Δ f-fs 2 should be divided in a full coverage manner to ensure that no missing detection occurs. The signal bandwidth can be divided by order of magnitude, and signals with different bandwidths use corresponding wavelet transform orders and wavelet filter lengths.
(4) Multi-scale signal detection by using mode maximum result of wavelet transformation with different orders
The broadband signal often has severe in-band fluctuation, and the fluctuation is easily misjudged as the narrowband signal under the small scale, so the signal detection is firstly carried out from the large signal, and once the large signal is judged to be the large signal, the signal detection under the small scale is not carried out on the frequency spectrum range, thereby avoiding the phenomenon that the in-band fluctuation of the broadband signal is misjudged as the narrowband signal. The algorithm implementation is shown in fig. 3.
(5) Estimating signal parameters based on the detection results
After the signal detection is completed, the signal carrier frequency f can be estimated according to the detection resultcBandwidth B, and carrier-to-noise ratio C/N. Let i-th signal start frequency f2i-1End frequency f2iThen signal bandwidth Bi＝f2i-f2i-1Carrier frequency fci＝(f2i-1+f2i-1)/2. The location of each signal is determined, as is the location of the "spectral holes".
