The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purposes of explanation, details are set forth. It is apparent to those skilled in the art that the present application can be practiced without using these specific details. In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the description of the present application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0078] First, the terms involved in the present application are explained:

[0079] ATSC 3.0: ATSC 3.0 (Advanced Television Systems Committee 3.0) is a new generation of digital television standard adopted by the broadcast television industry. It is an upgrade and improvement of the previous ATSC 1.0 standard, aiming to provide higher bandwidth and higher video resolution, richer broadcast television experience. The ATSC ATSC3.0 standard is a layered structure, which defines the standards of each layer from the physical layer, the transmission layer, the application layer, and the security layer.

[0080] Modulation mode: The modulation mode refers to a technology or method used in a wireless communication system to convert digital information into an analog signal for transmission. The modulation mode determines how the signal is transmitted and demodulated in the wireless medium. In the embodiments of the present application, a modulation mode is selected as a test standard, but the present solution is not limited to this modulation mode and is suitable for any modulation mode. The modulation mode is frequency 569MHz, code rate (coding rate) = 12 / 15, the number of multicarriers is 32K, and the interval protection length is 1024 symbol numbers.

[0081] The embodiments of the present application provide a signal quality determination method and device, electronic equipment and computer readable storage medium. Specifically, the embodiments of the present application provide a signal quality determination device suitable for electronic equipment, which includes a display device, such as a television (such as a liquid crystal display television, an LED television, a radio frequency television, etc.), a mobile phone, and can also be used in other intelligent devices that can receive signals and display images (such as a computer, a tablet computer, a smart watch, smart glasses, etc.).

[0082] In the prior art, the ATSC 3.0 standard does not define the specific standard of the signal quality progress bar, so different customers or enterprises have different signal quality progress bar algorithms in the determination and display of the signal quality progress bar. However, the result of the signal quality calculated by the existing algorithm for defining the signal quality progress bar is linearly changed, and cannot reflect the change of the signal quality with high sensitivity in some condition ranges that need to be paid special attention to.

[0083] Specifically, the signal quality determination method in the embodiments of the present application includes: obtaining an input carrier-to-noise ratio and calculating a target carrier-to-noise ratio; determining a target function from a plurality of calculation functions of a preset signal quality algorithm based on the calculated target carrier-to-noise ratio; and finally calculating and processing the target carrier-to-noise ratio by using the target function to obtain a signal quality value and displaying the signal quality value in a display area of a target device.

[0084] In summary, the preset signal quality algorithm in the embodiments of the present application can divide the signal quality curve into multiple curves, which can reflect the change of the signal quality with high sensitivity in some condition ranges that need to be paid special attention to, and reflect the change of the signal quality with low sensitivity in some condition ranges that do not need to be paid special attention to.

[0085] By using the embodiments of the present application, the sensitivity can be automatically adjusted according to different signal quality ranges to adapt to the change of the signal quality under different conditions, and the technical effect of clearly displaying the change of the signal quality in the condition range that needs to be paid special attention to in a limited display range and improving the user experience is achieved.

[0086] The following are described in detail, respectively. It should be noted that the order of the following embodiments is not limited as the priority order of the embodiments.

[0087] Referring to FIG. 1, FIG. 1 is a flowchart of a signal quality determination method provided by an embodiment of the present application. Although a logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown in the figure. Specifically, the specific process of the signal quality determination method is as follows:

[0088] S101: calculating a target carrier-to-noise ratio, wherein the target carrier-to-noise ratio is calculated based on an input carrier-to-noise ratio and a reference carrier-to-noise ratio;

[0089] In an embodiment of the present application, before calculating the target carrier-to-noise ratio, the input carrier-to-noise ratio received by the target device is first obtained; at the same time, the reference carrier-to-noise ratio set in advance by the target device is obtained.

[0090] Further, according to a pre-set difference calculation formula, the difference between the input carrier-to-noise ratio and the reference carrier-to-noise ratio is calculated, and the obtained difference is the target carrier-to-noise ratio.

[0091] It should be noted that in the embodiment of the present application, the reference carrier-to-noise ratio set in advance can be represented by C / N0, with the unit of dB; the input carrier-to-noise ratio can be represented by C / N rec , with the unit of dB; and the pre-set difference calculation formula is C / N rel = C / N rec -C / N0, wherein C / N rel represents the actual carrier-to-noise ratio received by the target device, i.e., the target carrier-to-noise ratio, with the unit of dB.

[0092] As an optional embodiment, taking a radio frequency television as the target device, a frequency of 569 MHz as the modulation mode, a code rate of 10 / 15, a number of 32K of multicarriers, a gap protection length of 1024 symbols, and a bandwidth of 6 MHz as examples. The current signal carrier-to-noise ratio C / N rec and the BER (bit error rate) are obtained from an ATSC 3.0 channel demodulation chip, and then according to the difference calculation formula: C / N rel = C / N rec -C / N0, the target carrier-to-noise ratio C / N rel is calculated; in the embodiment of the present application, the reference carrier-to-noise ratio C / N0 can be 19 dB.

[0093] It should be noted that the "high frequency head" refers to a technology in the physical layer, also known as "high frequency channel head". It is used to provide additional protection and interference resistance in wireless transmission. The signal quality value obtained from the high frequency head of ATSC3.0 is the input carrier-to-noise ratio mentioned above. The target device includes but is not limited to the above-mentioned radio frequency television, which can be a smart device capable of receiving signals and displaying images, such as: TV, mobile phone, computer, tablet computer, smart watch, smart glasses, etc. The target device can also have a signal quality indication function, which can be realized by a signal quality indicator (Signal Quality Indicator). The signal quality indicator is applied in the target device to display or measure the signal quality. The signal quality determination method is run on the target device, and the signal quality is displayed through the signal quality indication function.

[0094] In addition, the value of the reference carrier-to-noise ratio C / N0 is only an example (it can be any constant), which can be modified or set according to different devices, different models of devices, and various factors such as actual use scenarios and use environments. The difference calculation formula: C / N rel = C / N rec -C / N0, which can also be adjusted or modified accordingly according to actual conditions.

[0095] S102: Determine the target function from the preset signal quality algorithm based on the target carrier-to-noise ratio.

[0096] In the embodiments of the present application, the target carrier-to-noise ratio is calculated to determine the numerical interval to which the target carrier-to-noise ratio belongs.

[0097] It should be noted that the above numerical interval sets a first interval, a second interval and a third interval; the maximum value of the first interval is less than the minimum value of the second interval, and the maximum value of the second interval is less than the minimum value of the third interval.

[0098] As an optional embodiment, still taking the target device as a radio frequency television, the modulation mode as 569MHz frequency, the code rate (coding rate) = 10 / 15, the number of multicarriers as 32K, the interval protection length as 1024 symbol numbers, and the bandwidth 6MHz as an example. In the embodiments of the present application, the above three numerical intervals can be set as: the first interval (-∞, -A), the second interval [-A, A], and the third interval (A, +∞), where -A is the minimum value of the second interval, and A is the minimum value of the third interval.

[0099] It should be noted that the number of the above numerical intervals is not specifically limited, and can be set to three and other numbers; the numerical range of each numerical interval is also not specifically limited, and the numerical value of the numerical interval can be modified or set according to different device types, different models of the same device type, and various factors such as actual use scenarios and use environments. In the embodiments of the present application, A is preferably 3, but in actual application, A is not limited to the constant 3.

[0100] In the embodiments of the present application, the corresponding calculation function of the above numerical interval is obtained, and the above calculation function corresponding to the above numerical interval is determined as the above target function.

[0101] It should be noted that the above preset signal quality algorithm includes a plurality of different calculation functions, and each interval in the above plurality of numerical intervals corresponds to a calculation function.

[0102] As an optional embodiment, SQI can be used to represent the numerical value of the signal quality progress, and different numerical intervals correspond to a calculation function of the signal quality progress numerical value. For example, the first interval (-∞, -A) can use "SQI=0" to represent the signal quality progress numerical value; the second interval [-A, A] can use "SQI=(C / N rel +A)*BER_SQI" to represent the signal quality progress numerical value; and the third interval (A, +∞) can use "SQI=100" to represent the signal quality progress numerical value.

[0103] Optionally, using the calculation function in the above embodiments, it can be seen that the signal quality progress numerical value corresponding to the first interval is 0, the signal quality progress numerical value corresponding to the second interval is 0 to 100, and the signal quality progress numerical value corresponding to the third interval is 100.

[0104] That is, the target carrier-to-noise ratio range to which the user needs to pay special attention is [-A, A], and using the SQI=(C / N rel +A)*BER_SQI calculation function corresponding to this interval for calculation can make the signal quality progress numerical value corresponding to the target level value displayed in the 0-100 range of the progress bar, so that the user can intuitively and simply see the change of the signal quality, and the user can conveniently adjust the signal, such as adjusting the antenna position and length, thereby improving the user experience.

[0105] It should be noted that the above embodiments are only examples, and the number and calculation method of the calculation function can be modified according to actual application conditions, so as to facilitate the user to adjust the signal quality.

[0106] Optionally, as shown in FIG. 2, FIG. 2 is a flowchart of a method for determining a numerical interval to which a target carrier-to-noise ratio belongs, according to an embodiment of the present application. Although a logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown in the figure. Specifically, the specific process of the method for determining a numerical interval to which a target carrier-to-noise ratio belongs is as follows:

[0107] As an optional embodiment, the size relationship between the target carrier-to-noise ratio and a first preset value and a second preset value is determined to obtain a first determination result, wherein the first preset value is less than the second preset value; and based on the first determination result, the numerical interval to which the target carrier-to-noise ratio belongs is determined.

[0108] It should be noted that the first preset value can be set to be less than the second preset value, which is preferably 3 in the embodiment of the present application, but can be a constant other than 3 in actual application.

[0109] Optionally, in the above embodiment, the first preset value is set to -3 and the second preset value is set to 3.

[0110] If the target carrier-to-noise ratio is less than the first preset value, it is determined that the numerical interval to which the target carrier-to-noise ratio belongs is the first interval, wherein the calculation function corresponding to the first interval is a first function.

[0111] Specifically, when the target carrier-to-noise ratio C / N rel is less than -3 dB, the corresponding numerical interval is the first interval (-∞, -3), and the corresponding first function is: signal quality progress value SQI = 0, and the corresponding signal quality progress value is 0.

[0112] If the target carrier-to-noise ratio is greater than the second preset value, it is determined that the numerical interval to which the target carrier-to-noise ratio belongs is a third interval, wherein the calculation function corresponding to the third interval is a third function.

[0113] Specifically, when the target carrier-to-noise ratio C / N rel is greater than 3 dB, the corresponding numerical interval is the third interval (3, +∞), and the corresponding third function is: signal quality progress value SQI = 100, and the corresponding signal quality progress value is 100.

[0114] If the target carrier-to-noise ratio is less than or equal to the second preset value and greater than or equal to the first preset value, it is determined that the numerical interval to which the target carrier-to-noise ratio belongs is a second interval, wherein the calculation function corresponding to the second interval is a second function.

[0115] Specifically, when the target carrier-to-noise ratio C / N relgreater than or equal to -3dB and less than or equal to 3dB, the corresponding numerical interval is the above-mentioned second interval [-3, 3], and the corresponding second function is: signal quality progress numerical value SQI = (C / N rel + A) * BER_SQI, and the corresponding signal quality progress numerical value is 0 to 100.

[0116] As an optional embodiment, the test results obtained by using the above-mentioned multiple calculation functions to test the signal quality progress numerical value are shown in Table 1:

[0117] Table 1

[0118] It should be noted that the test conditions in Table 1 are that the modulation mode is frequency 569MHz, the code rate is 10 / 15, the number of multicarriers is 32K, the interval guard length is 1024 symbols, the bandwidth is 6MHz, the RF Input C / N (dB) is the input carrier-to-noise ratio C / N rec , the C / N ref is 19dB, the SQI min [%] and the SQI max [%] are the maximum and minimum values of the signal quality progress numerical value.

[0119] It should also be noted that there is a certain error between different devices, so there are maximum and minimum values of the signal quality progress numerical value.

[0120] S103: The target carrier-to-noise ratio is calculated and processed by using the above-mentioned target function to obtain a signal quality value.

[0121] In the embodiments of the present application, before the target carrier-to-noise ratio is substituted into the target function to obtain the signal quality value, first, the bit error rate received by the target device is obtained; and the bit error rate is calculated and processed to determine a bit error rate progress value; and then the target carrier-to-noise ratio and the bit error rate progress value are substituted into the target function to obtain the signal quality value.

[0122] Optionally, as shown in FIG. 3, FIG. 3 is a flowchart of a bit error rate progress value calculation method provided by the embodiments of the present application. Although a logical sequence is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown in the figure. Specifically, the specific process of the numerical interval judgment method to which the target carrier-to-noise ratio belongs is as follows:

[0123] Specifically, the size relationship between the bit error rate and the third preset value and the fourth preset value is determined to obtain a second judgment result, wherein the third preset value is less than the fourth preset value; based on the second judgment result, a bit error rate calculation function corresponding to the bit error rate is determined; and the bit error rate is substituted into the bit error rate calculation function to determine the bit error rate progress value.

[0124] If the error rate is less than a third preset value, i.e. BER < 10 -7 , the corresponding error rate calculation function is BER_SQI = (100 / 6); if the error rate is greater than or equal to the third preset value and less than or equal to a fourth preset value, i.e. 10 -7 ≤ BER ≤ 10 -4 , the corresponding error rate calculation function is BER_SQI = (100 / 15); if the error rate is greater than the fourth preset value, i.e. BER > 10 -4 , the corresponding error rate calculation function is BER_SQI = 0.

[0125] Optionally, taking the above numerical range and corresponding calculation function as an example, if the target carrier-to-noise ratio is less than -3dB, SQI is 0. If -3dB ≤ C / N rel ≤ 3dB, the value of BER_SQI (error rate progress value) needs to be calculated first. If BER (error rate) is greater than 10 -4 , BER_SQI = 0; if 10 -7 ≤ BER ≤ 10 -4 , BER_SQI = (100 / 15); if BER < 10 -7 , BER_SQI = (100 / 6). After BER_SQI is calculated, the value of SQI is calculated through the formula SQI = (C / N rel + 3) * BER_SQI. If C / N rel > 3dB, SQI is 100. Finally, the above signal quality value is displayed in the target display area of the target device.

[0126] It should be noted that the signal quality progress value in the embodiments of the present application is displayed in a specific numerical value, which can also be displayed in other forms in actual application, for example, displayed in a percentage corresponding to a specific numerical value, displayed in the form of a progress bar, etc.

[0127] According to the embodiments of the present application, the signal quality progress value SQI curve is divided into three sections, which can reflect the change of signal quality with high sensitivity in some condition ranges that need to be concerned, and reflect the change of signal quality with low sensitivity in some condition ranges that do not need to be concerned. For example, in the range of 3dB higher than the reference carrier-to-noise ratio value, it is a condition range that needs to be concerned, which can reflect the change of signal quality with high sensitivity. When the range is higher than 3dB, it is a strong signal quality, which does not need to reflect the change of signal quality with high sensitivity. When the range is lower than -3dB, it is a poor signal quality, which also does not need to reflect the change of signal quality with high sensitivity.
