[0063] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0064] In the related art, a receiver test scheme is to use simulation software modeling to simulate and evaluate the performance of a wireless communication receiver. However, this method does not perform joint dynamic modeling and simulation for the analog front end, digital front end and digital baseband of the wireless communication receiver, and cannot perform more accurate test and evaluation of the overall performance of the wireless communication receiver in the early stages of research and development. Furthermore, the performance impact of analog device characteristics, the performance impact of RF calibration scheme compensation errors, and the performance impact of the digital front end scheme must be left until the prototype receiver actual machine verification stage to be evaluated and corrected, and the cost of retrospective modification is high. Based on this, the present application proposes a receiver test method, device, electronic device, chip and storage medium. The receiver test method, device, electronic device, chip and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.

[0065] The embodiment of the present application is illustrated by the receiver test method being configured in a receiver test device, and the receiver test device can be applied to an electronic device or a chip so that the electronic device or the chip can perform a receiver test function. In addition, in some possible embodiments, the receiver test device can also be software in an electronic device, etc. Among them, the software is, for example, communication software, etc. Among them, the following embodiments are illustrated by taking the execution subject as an electronic device as an example.

[0066] Figure 1 A flowchart of a receiver testing method provided in an embodiment of the present application.

[0067] like Figure 1 As shown, the method may include the following steps:

[0068] Step 101: Generate a simulated receiving signal of a receiver based on first data.

[0069] The first data may refer to set communication data. For example, the first data may refer to a set binary sequence, that is, a 01 sequence.

[0070] The receiver may refer to the receiver designed in the scheme design stage. It should be noted that there is no actual receiver in the scheme design stage.

[0071] The simulated received signal refers to a wireless analog signal used for performance testing; the simulated received signal may refer to a simulated signal obtained after encoding and / or modulating the first data.

[0072] Step 102: Perform a simulated interference factor adding process on the simulated received signal to obtain a first intermediate signal.

[0073] Among them, adding simulated interference factors to the simulated received signal refers to adding the influence of the RF analog device to the simulated received signal. It should be noted that at least one simulated interference factor can be added to the simulated received signal. When adding multiple simulated interference factors to the simulated received signal, this application does not limit the order of adding multiple simulated interference factors.

[0074] In the embodiment of the present application, the analog interference factor addition process includes signal enhancement processing, thermal noise addition, phase noise addition, in-phase / quadrature-phase (I / Q) imbalance addition, analog filtering processing and DC leakage addition, etc.

[0075] It should be noted that the addition of simulated interference factors to the simulated received signal belongs to the processing function of the receiver analog front-end module.

[0076] Step 103: Sampling the first intermediate signal to obtain a second intermediate signal, wherein the sampling rate of the second intermediate signal matches the sampling rate required for baseband processing.

[0077] The sampling process on the first intermediate signal may refer to down-sampling the first intermediate signal to obtain a second intermediate signal matching a sampling rate required for baseband processing.

[0078] In the embodiment of the present application, the first intermediate signal may be sampled at least once.

[0079] It should be noted that sampling and processing the first intermediate signal belongs to the processing function of the digital front-end module of the receiver.

[0080] Step 104: perform baseband processing on the second intermediate signal to obtain second data extracted from the second intermediate signal.

[0081] The baseband processing of the second intermediate signal may refer to performing data extraction processing on the second intermediate signal to obtain second data recovered from the second intermediate signal.

[0082] It should be noted that baseband processing of the second intermediate signal belongs to the processing function of the digital baseband module of the receiver.

[0083] Step 105: Perform a performance test on the receiver according to the first data and the second data.

[0084] The first data and the second data may be compared for consistency, and based on the comparison result, the performance of the receiver may be tested.

[0085] like Figure 2 As shown, Figure 2 The schematic diagram of module interaction when performing performance testing on a receiver is shown in FIG. The wireless signal source generation module generates a simulated received signal based on the first data; the receiver analog front-end module performs a simulated interference factor addition process on the simulated received signal to obtain a first intermediate signal; the receiver digital front-end module performs sampling process on the first intermediate signal to obtain a second intermediate signal; the receiver digital baseband module performs baseband processing on the second intermediate signal to obtain second data; and the performance evaluation module performs a performance test on the receiver based on the first data and the second data.

[0086] In the receiver testing method of the embodiment of the present application, a simulated receiving signal of the receiver is generated based on the first data; the simulated receiving signal is subjected to a simulated interference factor adding process to obtain a first intermediate signal; the first intermediate signal is subjected to a sampling process to obtain a second intermediate signal, and the sampling rate of the second intermediate signal matches the sampling rate required for baseband processing; the second intermediate signal is subjected to baseband processing to obtain second data extracted from the second intermediate signal; and the performance of the receiver is tested based on the first data and the second data. The simulated interference factor adding process belongs to the processing function of the analog front-end module of the receiver, the sampling process belongs to the processing function of the digital front-end module of the receiver, and the baseband processing belongs to the processing function of the digital baseband module of the receiver. The present application adopts the joint dynamic modeling method of the receiver analog front-end module, the digital front-end module and the digital baseband module to perform performance simulation test and evaluation on the receiver, which integrates the main functional parts and influencing factors of the receiver, and can simulate the whole machine processing process of the receiver under the dynamic wireless signal reception of the air interface, and obtain a performance evaluation result that is closer to the actual machine test performance, thereby early discovering the performance problems of the whole machine solution after the integration of the analog front-end module, the digital front-end module and the digital baseband module solution.

[0087] Based on the above embodiments, Figure 3 A flowchart of another receiver testing method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the method comprises the following steps:

[0088] Step 301: Generate a simulated receiving signal of a receiver based on first data.

[0089] The relevant explanations in the aforementioned embodiments are also applicable to step 201 , and the principles are the same, which will not be described again here.

[0090] Step 302: Perform a simulated interference factor adding process on at least one sub-signal in the simulated received signal to obtain a first intermediate signal.

[0091] The process of the receiver receiving the simulated received signal is a continuous process. Therefore, the simulated received signal can be understood to be composed of sub-signals, and the simulated interference factor adding process is performed on the sub-signals.

[0092] In one implementation of the embodiment of the present application, simulated interference factor addition processing is performed on part or all of the sub-signals in the simulated received signal to obtain a first intermediate signal.

[0093] In an embodiment of the present application, for any target sub-signal in a simulated received signal, a target analog gain parameter of a reference sub-signal is obtained, wherein the reference sub-signal is a sub-signal in the simulated received signal whose timing is located before the target sub-signal; according to the target analog gain parameter, a target interference factor parameter of a target analog interference factor related to the analog gain strength is determined; based on the target interference factor parameter, a simulated interference factor is added to the target sub-signal to obtain a first intermediate sub-signal corresponding to the target sub-signal in the first intermediate signal.

[0094] As an example, the target sub-signal includes any sub-signal except the first sub-signal, and the reference sub-signal may refer to a sub-signal preceding the target sub-signal.

[0095] In addition to the first intermediate sub-signal, the sub-signal also corresponds to a second intermediate sub-signal; the target analog gain parameter of the reference sub-signal is determined based on the first signal power measured by the second intermediate sub-signal corresponding to the reference sub-signal and the second signal power measured for the first intermediate sub-signal corresponding to the reference sub-signal.

[0096] In one implementation of the embodiment of the present application, the target interference factor parameter of the target simulated interference factor may be a set value.

[0097] In another implementation of the embodiment of the present application, based on the mapping relationship between the analog gain parameter corresponding to the target analog interference factor and the interference factor parameter, the target interference factor parameter matched by the target analog gain parameter is queried.

[0098] Wherein, for any target simulated interference factor related to the simulated gain strength, the target simulated interference factor corresponds to an interference factor parameter table, and the interference factor parameter table is used to store the mapping relationship between the simulated gain parameters and the interference factor parameters.

[0099] It should be noted that if the simulated interference factor to be added is not related to the analog gain strength, the interference factor parameter corresponding to the simulated interference factor may be a set value.

[0100] In one implementation of the embodiment of the present application, before the simulated received signal is subjected to the processing of adding simulated interference factors, the simulated received signal may be subjected to frequency adjustment processing, and the simulated received signal after the frequency adjustment processing may be subjected to the processing of adding simulated interference factors to obtain a first intermediate signal, or, after the simulated received signal is subjected to the processing of adding simulated interference factors, the simulated received signal after the processing of adding simulated interference factors may be subjected to frequency adjustment processing to obtain a first intermediate signal.

[0101] The frequency adjustment processing and the simulated interference factor adding processing may be processing the sub-signals.

[0102] The frequency adjustment process includes adjusting the signal frequency based on a target analog frequency parameter, and the target analog frequency parameter is determined based on a baseband frequency domain offset measured for a second intermediate sub-signal corresponding to a reference sub-signal.

[0103] In one implementation of the embodiment of the present application, after the simulated interference factor is added to the simulated received signal, the simulated received signal after the analog interference factor is added can be subjected to analog-to-digital conversion (ADC) processing, that is, the simulated received signal after the analog interference factor is added is quantized, and the wireless analog signal is converted into a wireless digital signal. It should be noted that the first intermediate signal obtained after the ADC processing is a high sampling rate digital signal.

[0104] like Figure 4 As shown, Figure 4 The schematic diagram of the module interaction for the analog front-end module to perform frequency adjustment processing, analog interference factor addition processing and ADC processing on the simulated received signal. The frequency adjustment module adjusts the frequency of any target sub-signal in the simulated received signal based on the target simulated frequency parameter; the N analog factor modules perform analog interference factor addition processing on the target sub-signal after frequency adjustment; the ADC module performs analog-to-digital conversion on the target sub-signal after the analog interference factor addition processing to obtain the first intermediate sub-signal corresponding to the target sub-signal. Wherein, N is greater than or equal to 1.

[0105] like Figure 5 As shown, Figure 5 Schematic diagram of the processing of the simulation factor module. Taking the simulation factor module x as an example, the module is used to add the target simulation interference factor x. For the target sub-signal, based on the target simulation gain parameter of the reference sub-signal, the target interference factor parameter is selected from the interference factor parameter table, and then the target simulation interference factor x is added based on the target interference factor parameter.

[0106] It should be noted that the interference factor parameters in the interference factor parameter table are calculated or tested by RF R&D personnel based on the analog device selection parameters before modeling, and have real machine significance. Since the strength of the received signal changes dynamically, the analog factor module will follow the changes in the analog gain parameters and select the corresponding interference factor parameters to perform analog interference factor addition processing. Taking the analog interference factor addition processing as DC leakage addition as an example, different analog gain parameters correspond to DC leakage amplitude values ​​of different amplitudes. Based on this, the present application is closer to the processing status of the analog front end when the actual signal is received, and has a more real machine evaluation effect.

[0107] Step 303: Sample the first intermediate signal to obtain a second intermediate signal.

[0108] Step 304: perform baseband processing on the second intermediate signal to obtain second data extracted from the second intermediate signal.

[0109] Step 305: Perform a performance test on the receiver according to the first data and the second data.

[0110] The related explanations in the aforementioned embodiment are also applicable to step 303-step 304, and the principles are the same, which will not be repeated here.

[0111] In the receiver testing method of the embodiment of the present application, a simulated receiving signal of the receiver is generated based on the first data; a simulated interference factor is added to at least one sub-signal in the simulated receiving signal to obtain a first intermediate signal; the first intermediate signal is sampled to obtain a second intermediate signal, and the sampling rate of the second intermediate signal matches the sampling rate required for baseband processing; the second intermediate signal is baseband processed to obtain second data extracted from the second intermediate signal; and the performance of the receiver is tested based on the first data and the second data. Adding simulated interference factors to the sub-signals in the simulated receiving signal can more accurately simulate the complex interference conditions in the real environment, thereby improving the accuracy and practicality of the receiver performance test.

[0112] Based on the above embodiments, Figure 6 A flowchart of another receiver testing method provided in an embodiment of the present application is shown as follows: Figure 6 As shown, the method comprises the following steps:

[0113] Step 601: Generate a simulated receiving signal of a receiver based on first data.

[0114] Step 602: Perform a simulated interference factor adding process on the simulated received signal to obtain a first intermediate signal.

[0115] Among them, steps 601 to 602 can refer to the relevant explanations in the aforementioned embodiments, and the principles are the same, so they will not be repeated here.

[0116] Step 603, preprocessing the first intermediate signal before sampling processing, so as to use the signal obtained after preprocessing as the first intermediate signal to be sampled, wherein the preprocessing includes at least one of compensation processing and signal adjustment processing.

[0117] The aforementioned step 602 adds the influence of simulated interference factors to the simulated received signal, so this step needs to perform compensation processing on part of the simulated interference factors.

[0118] In the embodiment of the present application, the compensation processing includes compensation for DC leakage, compensation for IQ imbalance, compensation for uneven frequency response of analog filtering, etc.

[0119] In the embodiment of the present application, the signal adjustment processing may include at least one of frequency domain offset adjustment processing, time domain offset adjustment processing and amplitude adjustment processing.

[0120] Step 604, sampling the first intermediate signal, and post-processing the first intermediate signal after the sampling process to use the signal obtained by the post-processing as the second intermediate signal, wherein the post-processing includes at least one of compensation processing and signal adjustment processing.

[0121] It should be noted that step 603 and step 604 are in an and / or relationship, and this embodiment provides a situation where step 603 and step 604 are executed simultaneously.

[0122] Based on step 603 and step 604 , it can be seen that the present application does not limit the sequence of the sampling process, the compensation process, and the signal adjustment process.

[0123] Step 605: perform baseband processing on the second intermediate signal to obtain second data extracted from the second intermediate signal.

[0124] Step 606: Perform a performance test on the receiver according to the first data and the second data.

[0125] In the receiver testing method of the embodiment of the present application, a simulated receiving signal of the receiver is generated based on the first data; the simulated receiving signal is processed by adding simulated interference factors to obtain a first intermediate signal; the first intermediate signal before sampling is preprocessed to use the signal obtained after preprocessing as the first intermediate signal to be sampled, wherein the preprocessing includes at least one of compensation processing and signal adjustment processing; the first intermediate signal is sampled, and the first intermediate signal after sampling is post-processed to use the signal obtained after post-processing as the second intermediate signal, wherein the post-processing includes at least one of compensation processing and signal adjustment processing; the second intermediate signal is baseband processed to obtain second data extracted from the second intermediate signal; and the receiver is performance tested based on the first data and the second data. The present application performs compensation processing and signal adjustment processing, which can make the performance evaluation of the receiver closer to the actual machine evaluation effect, and the performance evaluation accuracy is higher.

[0126] Based on the above embodiments, Figure 7 A flowchart of another receiver testing method provided in an embodiment of the present application is shown as follows: Figure 7 As shown, the method comprises the following steps:

[0127] Step 701: Generate a simulated receiving signal of a receiver based on first data.

[0128] Step 702, for any target sub-signal in the simulated received signal, obtain the target analog gain parameter of the reference sub-signal; determine the target interference factor parameter of the target analog interference factor related to the analog gain strength according to the target analog gain parameter; based on the target interference factor parameter, perform analog interference factor addition processing on the target sub-signal to obtain the first intermediate sub-signal corresponding to the target sub-signal in the first intermediate signal.

[0129] Among them, step 701 to step 702 can refer to the relevant explanations in the aforementioned embodiment, and the principles are the same, so they will not be repeated here.

[0130] Step 703 , preprocessing the first intermediate sub-signal before sampling processing, so as to use the signal obtained after the preprocessing as the first intermediate sub-signal to be sampled.

[0131] Step 704 , sampling the first intermediate sub-signal, and post-processing the first intermediate sub-signal after the sampling, so as to use the signal obtained by the post-processing as the second intermediate sub-signal corresponding to the target sub-signal in the second intermediate signal.

[0132] The compensation processing included in the preprocessing in step 703 and the compensation processing included in the post-processing in step 704 include compensation processing based on target compensation parameters corresponding to the target analog interference factor related to the analog gain strength; wherein the target compensation parameters are determined by querying the mapping relationship between the analog gain parameters corresponding to the target analog interference factor and the compensation parameters based on the target analog gain parameters of the reference sub-signal; the reference sub-signal is a sub-signal in the simulated received signal whose timing is located before the target sub-signal.

[0133] Wherein, for any target analog interference factor related to the analog gain strength, the target analog interference factor corresponds to a compensation parameter table, and the compensation parameter table is used to store a mapping relationship between the analog gain parameter and the compensation parameter.

[0134] It should be noted that the compensation parameters in the compensation parameter table are calculated by the RF R&D personnel using the calibration scheme based on the analog device factor parameters before modeling, and have the error characteristics of the actual calibration results. The analog factor compensation module will select the corresponding compensation parameters to compensate the signal as the analog gain parameters change. Therefore, the present application is closer to the processing status of the digital front end when the actual signal is received, and the compensation parameters used are the error results obtained by the calibration calculation, which has a more real-machine evaluation effect. In addition, it should be noted that not every analog interference factor is related to the gain strength. These analog factor compensation modules do not require the input of analog gain parameters when modeling. The compensation parameter table only contains values ​​that are not related to gain, which can be directly used when performing performance evaluation.

[0135] In the embodiment of the present application, the reference sub-signal corresponds to a second intermediate sub-signal.

[0136] The signal adjustment processing included in the preprocessing in step 703 and the signal adjustment processing included in the post-processing in step 704 include performing signal frequency domain offset based on a target frequency domain offset; wherein the target frequency domain offset is determined based on a baseband frequency domain offset measured for a second intermediate sub-signal corresponding to a reference sub-signal.

[0137] The signal adjustment processing included in the preprocessing in step 703 and the signal adjustment processing included in the post-processing in step 704 include performing signal time domain offset based on a target time domain offset; wherein the target time domain offset is determined based on a baseband time domain offset measured for a second intermediate sub-signal corresponding to a reference sub-signal.

[0138] The signal adjustment processing included in the preprocessing in step 703 and the signal adjustment processing included in the post-processing in step 704 include signal amplitude adjustment based on the target digital gain parameter; wherein the target digital gain parameter is determined based on the first signal power measured for the first intermediate sub-signal corresponding to the reference sub-signal and the second signal power measured for the second intermediate sub-signal corresponding to the reference sub-signal.

[0139] like Figure 8 As shown, Figure 8 A schematic diagram of the module interaction for the digital front-end module to perform sampling processing, compensation processing and signal adjustment processing on the simulated received signal.
