Detailed Description
In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments, and the illustrative embodiments and descriptions thereof of the present application are used for explaining the present application and do not constitute a limitation to the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
An embodiment of the present application provides a spectrum processing method, as shown in fig. 1, the method may include at least the following steps:
In the embodiment of the application, the operation information of the user on the preset frequency band comprises two types, one type is the selection operation of the user, and the other type is the input operation of the user.
When the operation information of the user on the preset frequency band is the selection operation of the user, the preset frequency band is controlled to be displayed on the electronic equipment before the operation information of the user on the preset frequency band is received, so that the user can select the displayed preset frequency band.
In practical application, when a user performs a selection operation from a displayed preset frequency band, the selection operation can be completed in a completely selected mode of the input device, and the selection operation can also be completed in a clicking mode of the input device.
It is understood that the input device may be a mouse or a stylus, which is not limited in this embodiment.
When the operation information of the user on the preset frequency band is the input operation of the user, the user can input parameters in an input module of the electronic device.
When the operation information of the user on the preset frequency band is the operation information finished by the user through the complete selection of the input equipment, the first frequency band determined by responding to the operation information is the first frequency band completely selected by the user through the input equipment.
When the operation information of the user on the preset frequency band is the operation information finished by the user through clicking of the input equipment, the first frequency band determined by responding to the operation information is the frequency band between the first frequency value and the second frequency value, wherein the first frequency value and the second frequency value are obtained by the user through clicking of the preset frequency band through the input equipment.
In practical application, when the user determines the first frequency value and the second frequency value through a selection operation clicked by the input device, as shown in fig. 2, the method may specifically include the following steps:
The implementation of determining the first frequency value and the second frequency value by the user through the selection operation of clicking by the input device is described below by taking the preset frequency band of 30MHz to 3GHz, the preset spectrum resolution of 6.25KHz, the sampling rate of 102.4M, and the number of pre-sampling points of 16384 points as examples:
first a number of data points are determined:
where N is the number of the plurality of data points.
After the number of data points is obtained, the data points may be numbered and the numbered data points may be displayed on the electronic device.
Assuming that the number of the first data point selected by the user is 100000 and the number of the second data point is 103200, the determined first frequency value is 100000 × 6.25 ═ 655MHz, the determined second frequency value is 103200 × 6.25 ═ 675MHz, and correspondingly, the first frequency band is a frequency band corresponding to the 655 MHz-675 MHz bandwidth.
When the operation information of the user on the preset frequency band is the input operation of the user, in response to the operation information, the user can input a first parameter at the first input module, input a second parameter at the second input module, and use the frequency band between the first parameter and the second parameter as the first frequency band, where the first parameter corresponds to the start frequency value of the first frequency band, and the second parameter corresponds to the end frequency value of the first frequency band.
And 104, controlling to display the first frequency band according to the first spectrum resolution.
It can be understood that, when the electronic device displays the first frequency band according to the first spectral resolution, the frequency bands other than the first frequency band in the preset frequency band are still displayed according to the preset resolution.
According to the technical scheme provided by the embodiment of the application, the first spectrum resolution corresponds to the bandwidth of the first frequency band, so that when the bandwidth of the first frequency band changes, the determined first spectrum resolution is different, and further, for signals of any frequency in the preset frequency band, display with the first spectrum resolution different from the preset spectrum resolution can be realized through the operation information of a user, and therefore, even if the signal frequency of the signal to be analyzed is not an integral multiple of the preset spectrum resolution, the signal to be analyzed can be accurately determined from the preset frequency band by using the first spectrum resolution.
In yet another embodiment of the present application, step 103 may comprise:
and determining the first spectrum resolution corresponding to the first frequency band according to the bandwidth of the first frequency band and the corresponding relation between the preset bandwidth and the spectrum resolution.
According to the embodiment of the application, the determined first spectrum resolution is different according to the difference of the bandwidth of the first frequency band.
In practical application, since the bandwidth of the first frequency band is smaller than the bandwidth of the preset frequency band, the resolution of the first frequency spectrum is greater than the resolution of the preset frequency spectrum.
The embodiment of the application can preset the corresponding relation between the bandwidth and the spectrum resolution. After the first frequency band is determined, a first spectrum resolution corresponding to the first frequency band is determined based on the bandwidth and the corresponding relation of the first frequency band.
For example, the preset correspondence between the bandwidth and the spectrum resolution in the embodiment of the present application may be:
when the bandwidth is 60M, the frequency spectrum resolution is 3.725 KHz; when the bandwidth is changed by a certain multiple with reference to 60M, the spectral resolution is changed by the same multiple.
It should be noted that the bandwidth and the spectrum resolution in the above correspondence relationship in the embodiment of the present application may be determined according to actual situations, and the above example is only an optional implementation manner of the present invention.
Based on the specific implementation of the step 103, as shown in fig. 3, an embodiment of the present application provides a spectrum processing method, including:
step 303, determining a first spectrum resolution corresponding to the first frequency band according to the bandwidth of the first frequency band and a corresponding relation between a preset bandwidth and the spectrum resolution;
In another embodiment of the present application, when the operation information of the user is input by the user through the first input module and the second input module, as shown in fig. 4, the spectrum processing method may include the following steps:
In another embodiment of the present application, before displaying the first frequency band according to the first spectral resolution, the sampling rate corresponding to the preset frequency band may be updated by using the first spectral resolution.
Since the sampling rate is in direct proportion to the resolution ratio when the number of the pre-sampling points is fixed, the sampling rate corresponding to the preset frequency band can be updated by using the direct proportion relationship between the sampling rate and the resolution ratio after the first spectrum resolution ratio is determined.
Specifically, the method comprises the following steps:
the updated sampling rate is the first spectral resolution/the preset spectral resolution.
