Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for monitoring the intensity of a wide-band signal. Background Art

[0002] With the development of technology, wireless communication technologies have become increasingly mature. More and more radio receivers (such as Wi-Fi receivers and Bluetooth receivers) can transmit signals through wireless communication technologies. In the transmission of wireless signals by radio receivers, it is very important to perform gain control on the transmitted signals for wireless communication quality. To achieve high-quality gain control, it is necessary to rely on the monitoring of the intensity of the transmitted signals at the radio frequency front end. The more accurate the monitoring of the transmitted signal intensity, the more high-quality gain control can be achieved.

[0003] Currently, in the monitoring of the intensity of the transmitted signals of radio receivers, the monitoring of the transmitted signal intensity can be achieved by using only the analog method or the digital method. However, it has been found in practice that in the monitoring of the transmitted signal intensity by the analog method, the requirement for the chip integration degree of the radio receiver is high, and there is a problem of low monitoring accuracy of the transmitted signal intensity; in the monitoring of the transmitted signal intensity by the digital method, there will be a problem that the bandwidth of the digital signal used to calculate the signal intensity is smaller than the bandwidth of the signal passed by the radio frequency front end, resulting in a large area of blind spots in the monitoring of the transmitted signal intensity. Therefore, how to accurately monitor the intensity of the transmitted signals at the radio frequency front end is particularly important. Summary of the Invention

The following will be described in detail respectively.

[0079] Embodiment 1

[0080] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of a method for monitoring the signal strength of a wide frequency band disclosed in an embodiment of the present invention. As Figure 1 shown, the method for monitoring the signal strength of a wide frequency band may include the following operations:

[0081] 101. Respectively compare the voltage amplitudes of the target signal through multiple comparison circuits of the multi-gear comparison circuit to obtain a voltage comparison result corresponding to each comparison circuit, where the target signal is any transmission signal of wireless communication, and the voltage comparison result is an analog signal.

[0082] In an embodiment of the present invention, the target signal may be any transmission signal of wireless communication. For example, the target signal is a wireless communication transmission signal of a 2.4HZ frequency band wi-fi receiver. Further, the target signal is a wireless transmission signal in a radio frequency circuit. Further still, the target signal is a wireless transmission signal output from a transimpedance amplifier.

[0083] In an embodiment of the present invention, the multi-gear comparison circuit includes multiple comparison circuits. The target signal input to the multi-gear comparison circuit is an analog signal, and the target signal is respectively transmitted to each comparison circuit of the multi-gear comparison circuit, and a voltage comparison result corresponding to each comparison circuit is obtained according to each comparison circuit comparing the target signal.

[0084] 102. Quantify all voltage comparison results to obtain a quantization result corresponding to each voltage comparison result, where the quantization result is a digital signal.

[0085] 103. Calculate the target power corresponding to the target signal based on the determined digital signal power calculation model for the converted digital signal. The converted digital signal is obtained after the target signal is converted by an analog-to-digital converter.

[0086] In an embodiment of the present invention, a target signal is input into an analog-to-digital converter, where the target signal is the same as the wireless transmission signal input into the multi-gear comparison circuit in step 101. After the analog-to-digital converter converts the target signal from an analog signal to a digital signal, a converted digital signal is obtained. Subsequently, the converted digital signal is calculated through a digital signal power calculation model to automatically obtain the target power corresponding to the target signal.

[0087] In an optional embodiment, the converted digital signal includes a plurality of discrete sampling signals obtained by sampling the target signal by the analog-to-digital converter based on a determined sampling frequency;

[0088] Calculating the converted digital signal through the determined digital signal power calculation model to obtain the target power corresponding to the target signal may include:

[0089] Calculating all the discrete sampling signals based on a first formula to obtain the target power corresponding to the target signal;

[0090] Wherein, the first formula is:

[0091] Or

[0092] Wherein, P(n) is the target power corresponding to the target signal at the nth sampling moment, m is the sequence length of the discrete sampling signals used to calculate the target power, and y(i) is the ith discrete sampling signal.

[0093] In this optional embodiment, the sampling frequency can be flexibly adjusted according to actual needs, which is not limited in the embodiments of the present invention. The sampling moment can be determined through the determined sampling frequency, and the corresponding discrete sampling signals are collected at different sampling moments.

[0094] In this optional embodiment, for example, when the sequence length m of the discrete sampling signals used to calculate the target power is 10, and at the sampling moment n = 100, when calculating all the discrete sampling signals through the first formula, the obtained discrete sampling signals are: y(90), y(91), y(92), y(93), y(94), y(95), y(96), y(97), y(98), y(99), y(100). Finally, the target power corresponding to the target signal can be calculated through the following formula, P(100) = |y(90)| 2 +|y(91)| 2 …+|y(99)| 2 +|y(100)| 2 .

[0095] It can be seen that this optional embodiment can sample the target signal at a preset sampling frequency to obtain a discrete sampling signal, and automatically calculate the final target power based on the discrete sampling signal with a selected specific sequence length through a digital signal power calculation model, which can improve the power calculation accuracy of the signal.

[0096] 104. Calculate the intensity of the target signal based on all quantization results and the target power according to the determined joint decision model to obtain the target signal intensity value.

[0097] In another optional embodiment, calculating the intensity of the target signal based on all the quantization results and the target power according to the determined joint decision model to obtain the target signal intensity value includes:

[0098] Determine a plurality of preset signal intensity values based on the determined joint decision model, where each of the preset signal intensity values includes at least one corresponding preset condition;

[0099] For each of the preset signal intensity values, determine whether all the quantization results and the target power satisfy a certain preset condition corresponding to the preset signal intensity value. When it is determined that a certain preset condition corresponding to the preset signal intensity value is satisfied, determine the preset signal intensity value as the candidate signal intensity value;

[0100] Determine the target signal intensity value corresponding to the target signal from the set of candidate signal intensity values, where the set of candidate signal intensity values includes all the determined candidate signal intensity values.

[0101] In this optional embodiment, a plurality of preset signal intensity values determined by the joint decision model, where each preset signal intensity value corresponds to one or more preset conditions. When any preset condition corresponding to a certain preset signal intensity value is satisfied, then determine the preset signal intensity value as the candidate signal intensity value of the target signal.

[0102] It can be seen that this optional embodiment can determine the candidate intensity value of the target signal by determining whether the preset conditions of the preset signal intensity value determined by the joint decision model are satisfied, and the above operations can improve the calculation accuracy of the signal intensity.

[0103] In yet another optional embodiment, determining the target signal intensity value corresponding to the target signal from the set of candidate signal intensity values may include:

[0104] Select the candidate signal intensity value with the largest value from the set of candidate signal intensity values;

[0105] Determine the candidate signal intensity value with the largest selected value as the target signal intensity value corresponding to the target signal.

[0106] It can be seen that this optional embodiment can screen the candidate signal strength value with the largest value from the set of candidate signal strength values as the target signal strength value of the target signal, which can further improve the monitoring accuracy of the signal strength.

[0107] It can be seen that implementing the monitoring method for the wideband signal strength described in the embodiments of the present invention can compare and quantify the target signal in the analog signal state through multiple comparison circuits of a multi-gear comparison circuit to obtain a quantized digital signal, and calculate the power of the target signal that has completed analog-to-digital conversion through a digital signal power calculation model. Finally, according to the quantization result and the target power corresponding to the target signal, the target signal strength value is calculated through a joint determination model. Through the above operations, it is possible to combine the analog method and the digital method to monitor the transmission signal strength, which can reduce the signal monitoring blind area while improving the monitoring accuracy of the signal strength.

[0108] Embodiment 2

[0109] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of another monitoring method for wideband signal strength disclosed in the embodiments of the present invention. As Figure 2 shown, the monitoring method for wideband signal strength may include the following operations:

[0110] 201. Compare the voltage amplitude of the target signal with the threshold voltage corresponding to each comparison circuit. When the voltage amplitude of the target signal is greater than or equal to the threshold voltage corresponding to a certain comparison circuit, determine the voltage comparison result corresponding to this comparison circuit as a high-level signal. When the voltage amplitude of the target signal is less than the threshold voltage corresponding to a certain comparison circuit, determine the voltage comparison result corresponding to this comparison circuit as a low-level signal; where all voltage comparison results are: X1-X N , where N is the number of comparison circuits for voltage amplitude comparison in the multi-gear comparison circuit.

[0111] In the embodiments of the present invention, each comparison circuit in the multi-gear comparison circuit corresponds to a different threshold voltage, and this threshold voltage is used to compare with the target signal.

[0112] 202. Detect the level signals of all voltage comparison results X1-X N to obtain the level signal detection results corresponding to X1-X N respectively.

[0113] 203. Perform 1-bit quantization on all level signal detection results to obtain quantization results corresponding one-to-one to each level signal detection result. All quantization results are: x1-x N , where the quantization result is a timing signal.

[0114] In an embodiment of the present invention, after 1-bit quantization of all level signal detection results, a timing signal can be obtained. For example, all high-level signals are quantized and represented by 0, and all low-level signals are quantized and represented by 1.

[0115] For example, when the voltage comparison results X1 - X6 obtained in step 201 are high-level signals, high-level signals, high-level signals, low-level signals, low-level signals, and low-level signals respectively, the quantization results x1 - x after 1-bit quantization of these level signal detection results N are respectively: 0, 0, 0, 1, 1, 1.

[0116] 204. Calculate the converted digital signal based on the determined digital signal power calculation model to obtain the target power corresponding to the target signal. The converted digital signal is obtained after the target signal is converted by an analog-to-digital converter.

[0117] 205. Calculate the intensity of the target signal based on all quantization results and the target power according to the determined joint determination model to obtain the target signal intensity value.

[0118] In an embodiment of the present invention, for other descriptions of steps 201 - 205, please refer to the detailed descriptions of steps 101 - 104 in Embodiment 1, and the embodiments of the present invention will not be elaborated here.

[0119] In an embodiment of the present invention, multiple preset signal intensity values are determined based on the determined joint determination model. Each preset signal intensity value includes at least one corresponding preset condition. For each preset signal intensity value, it is judged whether all quantization results and the target power meet a certain preset condition corresponding to the preset signal intensity value. For the above process, for example, the joint determination model determines N preset signal intensity values corresponding to the comparison circuits one by one, which are preset signal intensity value 1 - preset signal intensity value N. Among them, the preset conditions corresponding to preset signal intensity value 1 may include condition 1: (x1(n) > 0 &&!ShiftEn), condition 2: [P(n) ≥ TH1 && (DTHEn1 || shiftEn)]; the preset conditions corresponding to preset signal intensity value 2 may include condition 1: (x2(n) > 0 &&!ShiftEn), condition 2: (x1(n) > 0 && ShiftEn), condition 3: [P(n) ≥ TH2 && DTHEn2]; the preset conditions corresponding to preset signal intensity value N may include condition 1: (x N (n) > 0 &&!ShiftEn), condition 2: (x N-1 (n) > 0 && ShiftEn), condition 3: [P(n) ≥ TH N && DTHEn N, where x1(n), x2(n) …… x N (n) represents the quantization result corresponding to the nth sampling moment in the process of collecting discrete sampling signals through the sampling frequency, x1 - x N The values of ShiftEn and DTHEn 1-N are 1-bit signals, and the values can be 1 or 0, which are given by an external control signal.

[0120] In an optional embodiment, determining multiple preset signal strength values based on the determined joint determination model may include:

[0121] Determining N preset signal strength values based on the determined joint determination model, and the preset signal strength values are respectively preset signal strength value 1 - preset signal strength value N. Among them, the N preset signal strength values correspond one-to-one to the N comparison circuits set in the multi-gear comparison circuit;

[0122] Or,

[0123] Determining M preset signal strength values based on the determined joint determination model, and the preset signal strength values are respectively preset signal strength value 1 - preset signal strength value M. Among them, M > N, and at least one of the N comparison circuits set in the multi-gear comparison circuit corresponds to multiple preset signal strength values.

[0124] It can be seen that this optional embodiment can obtain the gear information of the corresponding signal strength by determining the preset signal strength values corresponding one-to-one to the comparison circuits, which can improve the convenience of signal strength monitoring; or by determining the preset signal strength values more than the number of comparison circuits, and making one comparison circuit correspond to multiple preset signal strength values, the requirements for the accuracy and complexity of the comparison circuits set in the multi-gear comparison circuit can be further reduced, and the circuit setting cost can be reduced.

[0125] It can be seen that the method for monitoring the wideband signal strength described in the embodiments of the present invention can compare the target signal in the analog signal state through the N comparison circuits of the multi-gear comparison circuit to obtain the corresponding N voltage comparison results, and perform quantization on the N voltage comparison results to obtain the corresponding quantization results one by one. And calculate the power of the target signal that has completed analog-to-digital conversion through the digital signal power calculation model. Finally, according to the quantization result and target power corresponding to the target signal, the target signal strength value is automatically calculated through the joint determination model. Through the above operations, the monitoring of the transmission signal strength can be combined with the analog method and the digital method, which can reduce the signal monitoring blind area while further improving the monitoring accuracy of the signal strength.

[0129] A quantization module 302, configured to quantize all the voltage comparison results to obtain a quantization result corresponding to each of the voltage comparison results, where the quantization result is a digital signal;

[0130] A power calculation module 303, configured to calculate the target power corresponding to the target signal based on a determined digital signal power calculation model for the converted digital signal, where the converted digital signal is obtained by converting the target signal through an analog - to - digital converter;

[0131] A signal strength calculation module 304, configured to calculate the strength of the target signal based on all the quantization results and the target power according to a determined joint determination model, and obtain a target signal strength value.

[0132] It can be seen that the monitoring device for wide - band signal strength described in the embodiment of the present invention can compare and quantize a target signal in an analog signal state through multiple comparison circuits of a multi - gear comparison circuit to obtain a quantized digital signal, and calculate the power of the target signal that has completed analog - to - digital conversion through a digital signal power calculation model. Finally, according to the quantization result and the target power corresponding to the target signal, the target signal strength value is calculated through the joint determination model. Through the above operations, it is possible to combine the use of analog and digital methods to monitor the transmission signal strength, which can reduce the signal monitoring blind area while improving the monitoring accuracy of the signal strength.

[0133] In an optional embodiment, different comparison circuits correspond to different threshold voltages;

[0134] Among them, the specific manner in which the comparison module 301 respectively compares the voltage amplitudes of the target signal through multiple comparison circuits of the multi - gear comparison circuit to obtain a voltage comparison result corresponding to each of the comparison circuits is as follows:

[0135] Compare the voltage amplitude of the target signal with the threshold voltage corresponding to each comparison circuit. When the voltage amplitude of the target signal is greater than or equal to the threshold voltage corresponding to a certain comparison circuit, determine the voltage comparison result corresponding to this comparison circuit as a high-level signal. When the voltage amplitude of the target signal is less than the threshold voltage corresponding to a certain comparison circuit, determine the voltage comparison result corresponding to this comparison circuit as a low-level signal;

[0136] Among them, all the voltage comparison results are: X1 - X N , where N is the number of comparison circuits used for voltage amplitude comparison in the multi-gear comparison circuit.

[0137] It can be seen that the monitoring device for wide-band signal strength described in the embodiments of the present invention can compare the target signal in the analog signal state through N comparison circuits of the multi-gear comparison circuit, obtain the corresponding N voltage comparison results, quantize the N voltage comparison results to obtain the corresponding quantization results one by one, and calculate the power of the target signal after analog-to-digital conversion through the digital signal power calculation model. Finally, according to the quantization result and target power corresponding to the target signal, the target signal strength value is automatically calculated through the joint determination model. Through the above operations, the monitoring of the transmission signal strength can be combined with the analog method and the digital method, which can reduce the signal monitoring blind area and further improve the monitoring accuracy of the signal strength.

[0138] In another optional embodiment, the specific manner in which the quantization model quantizes all the voltage comparison results to obtain the quantization results corresponding to each voltage comparison result is as follows:

[0139] Detect the level signals of all the voltage comparison results X1 - X N to obtain the level signal detection results corresponding to X1 - X N respectively;

[0140] Perform 1-bit quantization on all the level signal detection results to obtain the quantization results corresponding one by one to each level signal detection result. All the quantization results are: x1 - x N , where the quantization result is a timing signal.

[0141] It can be seen that this optional embodiment can perform 1-bit quantization on N voltage comparison results to obtain the corresponding quantization timing signal results, which can improve the quantization effect of the signal.

[0142] In yet another optional embodiment, the specific manner in which the power calculation module 303 calculates the target power corresponding to the target signal based on the determined digital signal power calculation model for the converted digital signal is as follows:

[0143] Sample the converted digital signal based on the determined sampling frequency to obtain a plurality of discrete sampling signals corresponding to the converted digital signal;

[0144] Based on the plurality of discrete sampling signals, calculate the converted digital signal according to the first formula to obtain the target power corresponding to the target signal;

[0145] Wherein, the first formula is:

[0146] Or

[0147] Wherein, P(n) is the target power corresponding to the target signal at the nth sampling moment, m is the sequence length of the discrete sampling signal used to calculate the target power, and y(i) is the discrete sampling signal corresponding to the converted digital signal.

[0148] It can be seen that the optional embodiment can sample the target signal through a preset sampling frequency to obtain discrete sampling signals, and automatically calculate the final target power according to the discrete sampling signals of a specific selected sequence length through a digital signal power calculation model, which can improve the power calculation accuracy of the signal.

[0149] In another optional embodiment, the signal strength calculation module 304 calculates the strength of the target signal based on all the quantization results and the target power according to the determined joint decision model. The specific way to obtain the target signal strength value is as follows:

[0150] Determine a plurality of preset signal strength values based on the determined joint decision model, wherein each preset signal strength value includes at least one corresponding preset condition;

[0151] According to all the quantization results and the target power, determine whether a certain preset condition corresponding to the target preset signal strength value is satisfied, wherein the target preset signal strength value is any one of the preset signal strength values;

[0152] When it is determined that a certain preset condition corresponding to the target preset signal strength value is satisfied, determine the target preset signal strength value as the candidate signal strength value, and form a candidate signal strength value set with all the candidate signal strength values;

[0153] Determine the target signal strength value corresponding to the target signal from the candidate signal strength value set.

[0154] It can be seen that the optional embodiment can determine the candidate strength value of the target signal by determining whether the preset condition of the preset signal strength value determined by the joint decision model is satisfied, and the above operations can improve the calculation accuracy of the signal strength.

[0155] In yet another alternative embodiment, the specific manner in which the signal strength calculation model determines the target signal strength value corresponding to the target signal from the set of candidate signal strength values is as follows:

[0156] Filter out the candidate signal strength value with the largest numerical value from the set of candidate signal strength values;

[0157] Determine the candidate signal strength value with the largest numerical value filtered out as the target signal strength value corresponding to the target signal.

[0158] It can be seen that this alternative embodiment can further improve the monitoring accuracy of the signal strength by filtering out the candidate signal strength value with the largest numerical value from the set of candidate signal strength values as the target signal strength value of the target signal.

[0159] In yet another alternative embodiment, the specific manner in which the signal strength calculation model determines multiple preset signal strength values based on the determined joint determination model is as follows:

[0160] Based on the determined joint determination model, determine N preset signal strength values, which are respectively preset signal strength value 1 - preset signal strength value N. Among them, the N preset signal strength values correspond one-to-one to the N comparison circuits set in the multi-gear comparison circuit;

[0161] Or,

[0162] Based on the determined joint determination model, determine M preset signal strength values, which are respectively preset signal strength value 1 - preset signal strength value M. Among them, M > N, and at least one of the N comparison circuits set in the multi-gear comparison circuit corresponds to multiple preset signal strength values.

[0163] It can be seen that this alternative embodiment can obtain the gear information of the corresponding signal strength by determining the preset signal strength values corresponding one-to-one to the comparison circuits, which can improve the monitoring convenience of the signal strength; or by determining preset signal strength values more than the number of comparison circuits, and making one comparison circuit correspond to multiple preset signal strength values, it can further reduce the requirements for the accuracy and complexity of the comparison circuits set in the multi-gear comparison circuit, and reduce the circuit setting cost.
