Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0057] Embodiment 1:

[0058] As Figure 1 shown, this embodiment provides a 5G signal spectrum detection method, which includes the following steps:

[0059] S101. Determine the acquisition card parameters and spectrum parameters, and set the acquisition card clock.

[0060] The global parameters in this embodiment include acquisition card parameters and spectrum parameters. The acquisition card parameters include gain, number of sampling points, and acquisition card bandwidth. The spectrum parameters include spectrum center frequency, span, time slot, and time delay.

[0061] Determine the spectrum parameters. For example: the spectrum center frequency is set to 2524.85 MHz; the span is set to 1000e6 Hz; the time slot, 0 - 279, such as CSI - RS: 12; the time delay, in seconds, such as 0.003 seconds. Specifically, the spectrum parameters in this embodiment are general parameters of the wireless signal spectrum.

[0062] Determine the acquisition card parameters. For example: the acquisition card bandwidth is set to be less than or equal to the maximum bandwidth supported by the acquisition card; the gain is set to 65.

[0063] In this embodiment, the number of sampling points of the acquisition card = bw / 280 * 0.01, where bw represents the acquisition card bandwidth.

[0064] S102. Calculate the number of times the acquisition card should be sampled.

[0065] In this embodiment, according to the span and acquisition card bandwidth set in step S101, calculate the number of times m that the acquisition card should be sampled, as shown in the following formula:

[0066]

[0067] where ceil() represents the ceiling function, span represents the span, and bw represents the acquisition card bandwidth.

[0068] S103. Initialize the number of times the acquisition card has been sampled.

[0069] In this embodiment, perform an initialization process on the number of times the acquisition card has been sampled, and obtain that the number of times n that the acquisition card has been sampled is 0.

[0070] S104. Synchronize and time the acquisition card clock to set the time of the acquisition card clock to zero.

[0071] In this embodiment, use the GPS positioning system to perform a GPS synchronous time - setting on the acquisition card clock once, so that the time of the acquisition card clock returns to 0.

[0072] In this embodiment, the purpose of using GPS synchronous timekeeping is that the target base station is also calibrated for time through the GPS positioning system. Therefore, both the acquisition card and the target base station are in the GPS synchronous state, and the acquisition card can collect correct and expected data sets, making it easier to detect problems with the target base station.

[0073] S105. Calculate the specified time according to the current time of the acquisition card clock.

[0074] The specific formula for the specified time in this embodiment is as follows:

[0075]

[0076] Where time represents the specified time, now represents the current time of the acquisition card clock, slot represents the time slot, and sleep represents the time delay.

[0077] S106. Calculate the center frequency of the acquisition card according to the acquisition card parameters, spectrum parameters, and the number of times the acquisition card has been collected.

[0078] The specific formula for the center frequency of the acquisition card in this embodiment is as follows:

[0079]

[0080] Where c represents the center frequency of the acquisition card, freq represents the center frequency of the spectrum, span represents the span, bw represents the bandwidth of the acquisition card, and n represents the number of times the acquisition card has been collected.

[0081] S107. Based on the center frequency of the acquisition card and according to the specified time, use the acquisition card to collect data of the target base station.

[0082] Based on the center frequency of the acquisition card, starting from the specified time, use the acquisition card to collect an IQ data set with a specified number of sampling points of the target base station, where I: in-phase represents the in-phase; Q: quadrature represents the quadrature, with a 90-degree phase difference from the I phase.

[0083] The above acquisition by the acquisition card is one acquisition.

[0084] The IQ data set with the specified number of sampling points of the target base station in this embodiment is the data of the target base station.

[0085] S108. According to the data of the target base station, obtain an intermediate array and increment the number of times the acquisition card has been collected by one.

[0086] In this embodiment, the array after performing the Fourier transform on the data of the target base station is stored in the intermediate array, and n = n + 1 is executed.

[0087] S109. Compare the added number of times the acquisition card has been collected with the number of times it should be collected, and output the judgment result.

[0088] S110. Determine whether to detect the signal based on the judgment result.

[0089] The specific steps of step S110 are as follows:

[0090] If the judgment result is that the sum of the number of times of collected data and the number of times of data to be collected are equal, then display the intermediate array, implement signal detection according to the intermediate array, re - execute step S103, and execute the subsequent steps;

[0091] If the judgment result is that the sum of the number of times of collected data and the number of times of data to be collected are not equal, then continue to execute step S105 and execute the subsequent steps.
