In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.

As described in the background section, the construction of a simulated radio frequency environment is achieved by restoring the acquired radio frequency signals. Due to the wide frequency spectrum range of the complex radio frequency signals, under the condition of keeping signal detail characteristics, the difficulty of directly adopting the acquired complex radio frequency signals for reduction is very high, and more precise devices are needed for acquiring and reducing the complex radio frequency signals. On one hand, the manufacturing and maintenance costs of a more precise device are high, and on the other hand, the situation that the restored complex radio frequency signal cannot keep the signal detail characteristics may still exist in the more precise device, so that the difficulty in restoring the complex radio frequency signal is high, and the difficulty in constructing a simulation radio frequency environment through the complex radio frequency signal is increased.
In view of this, an embodiment of the present application provides a method for generating a radio frequency signal, and with reference to fig. 1, the method includes the following steps:
In this step, the initial signal is a signal having a frequency point within a first predetermined frequency range, which may be 0-949MHz for example. The initial signal within the first preset frequency range does not require a higher precision component in the acquisition and reduction process because the frequency range is relatively small. The detail characteristics of the initial signal can still be kept in the process of digitally acquiring the initial signal through the AD acquisition device and restoring the acquired data into the initial signal by utilizing the DA playback device, wherein the detail characteristics of the initial signal comprise the frequency characteristics and the energy characteristics of the signal. The number of initial signals determines the complexity of the rf signal, and the greater the number of initial signals, the higher the complexity of the rf signal that is finally generated. By generating complex radio frequency signals, the efficiency of constructing various simulated radio frequency environments required by users is improved, and therefore, a plurality of initial signals need to be acquired. For example, the frequency point of the initial signal may be in the range of 0-949MHz, the frequency point of the initial signal may be in the range of 50MHz-100MHz, and the frequency point of the initial signal may also be in the range of 500MHz-550 MHz.
102, mixing the plurality of initial signals based on a frequency width corresponding to the initial signals and a second preset frequency range to obtain a plurality of mixed signals.
In this step, the bandwidth corresponding to the signal refers to the amount of data transmitted by the signal within a fixed time, and is used to indicate the data transmission capability of the signal. The second preset frequency range is determined according to actual requirements of a user on simulation of a radio frequency environment, illustratively, based on the purpose of obtaining a complex radio frequency signal, a frequency point corresponding to an initial signal needs to be mixed into a higher frequency point, the frequency point in the second preset frequency range is larger than the frequency point in the first preset frequency range, and the complex radio frequency signal can be obtained through the mixed frequency signal in the second preset frequency range. It should be noted that, based on the purpose of obtaining the simple radio frequency signal, the frequency point in the second preset frequency band range may be the same as the frequency point in the first preset frequency band range, where the simple radio frequency signal is a signal that can still retain detailed characteristics after performing signal reduction on the acquired data, and the simple radio frequency signal may be obtained through the mixing signal in the second preset frequency band range, so that the efficiency of obtaining the simple radio frequency signal by the user is improved, and the purpose of simulating the radio frequency environment by the user according to actual requirements is achieved. Illustratively, the second predetermined frequency band may be 950MHz to 2150MHz, or may be 0 to 949MHz. The mixing is a process of changing a signal frequency point from one magnitude value to another magnitude value, the detailed characteristics of the signal cannot be changed along with the change of the signal frequency point, and the detailed characteristics of the signal can still be reserved after the signal is mixed. And mixing the initial signal with a local oscillation signal generated by the mixing equipment to generate a mixing signal. The frequency points corresponding to the local oscillator signals need to be controlled within a second preset frequency range, the initial signals can be placed at specific frequency points of the specific frequency range by controlling the frequency points corresponding to the local oscillator signals, the frequency points corresponding to the initial signals within the first preset frequency range are converted into the second preset frequency range, and the change of the frequency points corresponding to the initial signals is realized, so that a user can simulate the radio frequency environment according to actual requirements.
For example, as shown in fig. 2, fig. 2 is a schematic diagram of performing frequency mixing on a plurality of initial signals according to an embodiment of the present application, where the initial signals with a bandwidth of 50M and a frequency point within a frequency band range of 50MHz to 100MHz are subjected to frequency mixing, so that a frequency mixed signal with a bandwidth of 50M and a frequency point within a frequency band range of 950MHz to 1000MHz can be obtained, a frequency mixed signal with a bandwidth of 50M and a frequency point within a frequency band range of 1000MHz to 1050MHz can also be obtained, and a frequency mixed signal with a bandwidth of 50M and a frequency point within a frequency band range of 1050MHz to 1100MHz can also be obtained. The frequency range of the mixing signal is within a second preset frequency range, the frequency range of the mixing signal is within 950MHz-2150MHz, and the second preset frequency range may be 950MHz-1100MHz.
And 103, combining the plurality of mixing signals to obtain a plurality of radio frequency signals within the second preset frequency range.
In this step, a plurality of mixing signals are combined within a second predetermined frequency range, thereby generating a complex rf signal, which retains the detailed characteristics of the signal. By generating the complex radio frequency signals, the diversity of the radio frequency signals can be realized, the requirement for generating the radio frequency signals of a specific frequency band is met, and the technical problem that the complex radio frequency signals are difficult to restore in the prior art is solved. The initial signals are collected and restored, then the initial signals are subjected to frequency mixing to obtain frequency mixing signals, and the frequency mixing signals are combined to generate complex radio frequency signals. The complex radio-frequency signals to be restored are obtained by generating the complex radio-frequency signals, so that the detailed characteristics of the complex radio-frequency signals are reserved, the difficulty of restoring the complex radio-frequency signals is reduced, and the difficulty of constructing a simulation radio-frequency environment through the complex radio-frequency signals is also reduced.
For example, as shown in fig. 3, fig. 3 is a schematic diagram illustrating that a plurality of mixing signals are combined according to an embodiment of the present disclosure, and the frequency bandwidth is 50M and the frequency points are respectively within the frequency ranges of 950MHz to 1000MHz, 1000MHz to 1050MHz, and 1050MHz to 1100MHz, so as to generate a radio frequency signal with the frequency bandwidth of 150M and the frequency points within the frequency range of 950MHz to 1100MHz.
Through the scheme, the signal detail characteristics can be well reserved by acquiring the plurality of initial signals within the first preset frequency range. And mixing a plurality of initial signals based on the frequency width corresponding to the initial signals and a second preset frequency range to obtain a plurality of mixed signals, and converting the frequency point corresponding to the initial signals in the first preset frequency range into the second preset frequency range to change the frequency point corresponding to the initial signals. The mixing signals are combined to obtain a plurality of radio frequency signals within the second preset frequency range, so that the generation of complex radio frequency signals is realized, the technical problem of high difficulty in restoring the complex radio frequency signals in the prior art is solved, and the difficulty in constructing a simulation radio frequency environment through the complex radio frequency signals is reduced.
In some embodiments, the acquiring a plurality of initial signals within a first preset frequency band includes: acquiring a plurality of original signals within the first preset frequency range; in response to the number of original signals meeting a preset rule being greater than a number threshold, determining all original signals meeting the preset rule as the plurality of original signals; and in response to the number of the original signals meeting the preset rule being less than or equal to the number threshold, copying the original signals meeting the preset rule until the number of the original signals meeting the preset rule is greater than the number threshold, and determining all the original signals meeting the preset rule as the plurality of initial signals.
In this embodiment, the original signal is obtained through a signal source, where the signal source includes a playback signal source for playing back a sample signal, a vector signal source, and other types of various signal sources. The original signal includes a useful signal and a useless signal, and the useless signal is generated along with the useful signal, but the useless signal can cause damage to the useful signal. Therefore, the original signal needs to be screened, so as to screen out the useful signal, i.e. the original signal meeting the preset rule. Under the condition that the obtained original signals meeting the preset rules are enough, the original signals meeting the preset rules do not need to be copied, otherwise, the original signals meeting the preset rules need to be copied, so that the number of the original signals meeting the preset rules is larger than the number threshold. The quantity threshold is set according to the actual situation of the user constructing the simulation radio frequency environment, the quantity threshold can be relatively large under the condition that the quantity of the signal sources is large, and the quantity threshold can be relatively small under the condition that the quantity of the signal sources is small.
By copying the original signals meeting the preset rules, the requirements for the number of signal sources are reduced, the number requirements of AD acquisition devices and DA playback devices are further reduced, and the economic cost for acquiring the original signals is reduced. However, copying the original signal satisfying the preset rule also has certain disadvantages, so that the detail characteristics of the obtained original signal are single. The user can determine the acquisition mode of the initial signal according to the actual requirement for constructing the simulated radio frequency environment, illustratively, the user can only collect one original signal meeting the preset rule under the condition of considering economic cost, and copy the original signal meeting the preset rule until the number of the original signals meeting the preset rule is greater than the number threshold value, so that a plurality of initial signals are acquired. Under the condition that the user considers the diversity of the detail characteristics and the economic cost of the initial signals, a certain number of original signals can be obtained through the signal source, and then the original signals meeting the preset rules are respectively copied until the number of the original signals meeting the preset rules is larger than the number threshold, so that the multiple initial signals are obtained. Under the condition that the diversity of the detailed characteristics of the initial signals is considered, a user can acquire the initial signals which reach the quantity threshold and meet the preset rule through enough signal sources, and further acquire a plurality of initial signals.
For example, as shown in fig. 4, fig. 4 is a schematic diagram illustrating that an initial signal is copied according to an embodiment of the present application, and the initial signal with a bandwidth of 50M and a frequency point between 50MHz and 100MHz may be copied into a plurality of initial signals with a frequency point between 50MHz and 100MHz.
In some embodiments, the mixing includes up-converting and down-converting, the mixing signals include up-converting signals and down-converting signals, and mixing the plurality of initial signals based on a bandwidth corresponding to the initial signals and a second predetermined frequency band range to obtain a plurality of mixing signals, including: and carrying out up-conversion and/or down-conversion on the plurality of mixing signals to obtain a plurality of up-conversion signals and a plurality of down-conversion signals.
In this embodiment, in the prior art, the up-conversion is to mix the initial signal with the local oscillator signal generated by the frequency mixing device, and then to take the upper sideband signal after the frequency mixing, and the down-conversion is to mix the initial signal with the local oscillator signal generated by the frequency mixing device, and then to take the lower sideband signal after the frequency mixing. However, in this embodiment, the upper sideband signal and the lower sideband signal after the up-conversion and/or the down-conversion are taken as the initial signal after the up-conversion and/or the down-conversion. In this embodiment, the initial signal is subjected to up-conversion and/or down-conversion, the generated mixing signal includes an upper sideband signal and a lower sideband signal, the upper sideband signal and the lower sideband signal are mirror signals, and the frequency points of the upper sideband signal and the lower sideband signal can be controlled by controlling the frequency points corresponding to the local oscillation signals generated by the mixing device. The change of the frequency points corresponding to the initial signals is realized, the generation efficiency of the mixing signals is further improved, and the combination efficiency of the mixing signals is further improved.
In some embodiments, after acquiring a plurality of initial signals within a first preset frequency band range, the method comprises: gain adjusting at least one of the plurality of initial signals.
In this embodiment, the initial signals have different energy intensities, the gain is adjusted to amplify or reduce the energy of the initial signals, so as to achieve the purpose of controlling the energy composition of the initial signals and screening out the initial signals required by the user, the initial signals required by the user are determined according to the radio frequency test, and the constructed simulated radio frequency environment provides a test environment for the radio frequency test.
In some embodiments, gain adjusting at least one of the plurality of initial signals comprises: and screening the plurality of initial signals based on a first preset screening rule, and performing gain adjustment on the screened at least one initial signal, wherein the first preset screening rule is a rule for screening the plurality of initial signals.
In this embodiment, the gain adjustment can be performed for the initial signal with a specific energy intensity by the first preset screening rule. The energy composition of the initial signal can be controlled through gain adjustment, and the initial signal of the current actual demand of the user is determined. The first preset screening rule is a rule for screening the initial signal according to the current actual demand of the user. For example, the first preset frequency band range may be 0-100MHz, and when a user wants to screen out an initial signal of 0-25MHz, the energy corresponding to the initial signal of 0-25MHz may be amplified, or the energy corresponding to the initial signal of 25MHz-100MHz may be reduced.
In some embodiments, after mixing a plurality of initial signals based on a bandwidth corresponding to the initial signals and a second predetermined frequency band range to obtain a plurality of mixed signals, the method includes: gain adjustment is performed on at least one of the plurality of mixed signals.
In this embodiment, the mixing signals have different energy intensities, and the energy of the mixing signals can be controlled by adjusting the gain, so as to obtain the mixing signals with specific energy intensities, thereby meeting the requirement of a user for obtaining the required mixing signals.
In some embodiments, gain adjusting at least one of the plurality of mixed signals comprises: and screening the plurality of mixing signals based on a second preset screening rule, and performing gain adjustment on the screened at least one mixing signal, wherein the second preset screening rule is a rule for screening the plurality of mixing signals.
In this embodiment, the gain adjustment may be performed for the mixed signal with a specific energy intensity by using the second preset filtering rule. The mixing signals with different energy levels can be constructed through gain adjustment, so that the energy composition of the mixing signals is controlled, and the requirement of generating the mixing signals with specific energy is met. The second preset screening rule is a rule for screening the mixing signals according to the current actual requirements of the users. For example, the second preset frequency band may be 950MHz to 1100MHz, and a user wants to screen out the 950MHz to 1000MHz mixing signal, may amplify energy corresponding to the 950MHz to 1000MHz mixing signal, and may also reduce energy corresponding to the 1000MHz to 1100MHz mixing signal.

The second preset frequency band range can be 950MHz-1400MHz, the frequency width is 150M, the radio frequency signal with the frequency point in 950MHz-1100MHz is obtained by combining a plurality of mixing signals with the frequency width of 50M and the frequency points in the frequency band ranges of 950MHz-1000MHz, 1000MHz-1050MHz and 1050MHz-1100MHz respectively.
