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

[0064] In related technologies, one receiver testing scheme uses simulation software to model and evaluate the performance of a wireless communication receiver. However, this method does not perform joint dynamic modeling and simulation of the analog front-end, digital front-end, and digital baseband of the wireless communication receiver. This prevents more accurate testing and evaluation of the overall performance of the wireless communication receiver in the early stages of development. Consequently, the performance impact of analog device characteristics, the performance impact of RF calibration error compensation, and the performance impact of the digital front-end scheme can only be evaluated and corrected at least during the prototype receiver's actual verification stage, resulting in high retrospective modification costs. Based on this, this application proposes a receiver testing method, apparatus, electronic device, chip, and storage medium. The following description, with reference to the accompanying drawings, describes the receiver testing method, apparatus, electronic device, chip, and storage medium according to embodiments of this application.

[0065] This application illustrates an example where the receiver testing method is configured in a receiver testing apparatus. This apparatus can be applied to an electronic device or chip to enable it to perform receiver testing functions. Additionally, in some possible embodiments, the receiver testing apparatus can also be software within the electronic device. For example, this software could be communication software. The following embodiments will use an electronic device as an example for illustration.

[0066] Figure 1 This is a schematic flowchart of a receiver testing method provided in an embodiment of this application.

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

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

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

[0070] Here, the receiver can refer to the receiver designed and completed during the scheme design phase. It should be noted that there is no actual receiver during the scheme design phase.

[0071] Among them, the simulated received signal refers to the wireless analog signal used in the performance test; the simulated received signal can be the simulated signal obtained after encoding and / or modulating the first data.

[0072] Step 102: Perform simulated interference factor addition processing on the simulated received signal to obtain the first intermediate signal.

[0073] The process of adding simulated interference factors to the simulated received signal refers to adding the influence of radio frequency analog devices to the simulated received signal. It should be noted that at least one simulated interference factor can be added to the simulated received signal, and when multiple simulated interference factors are added, this application does not limit the order in which they are added.

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

[0075] It should be noted that adding simulated interference factors to the simulated received signal is a processing function of the receiver's analog front-end module.

[0076] Step 103: Sample the first intermediate signal to obtain the second intermediate signal. The sampling rate of the second intermediate signal matches the sampling rate required for baseband processing.

[0077] Here, sampling processing of the first intermediate signal can refer to downsampling the first intermediate signal to obtain a second intermediate signal that matches the sampling rate required for baseband processing.

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

[0079] It should be noted that sampling the first intermediate signal is a processing function of the receiver's digital front-end module.

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

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

[0082] It should be noted that baseband processing of the second intermediate signal is a function of the receiver's digital baseband module.

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

[0084] Among them, the consistency of the first data and the second data can be compared, and the performance of the receiver can be tested based on the comparison results.

[0085] like Figure 2 As shown, Figure 2 This diagram illustrates the module interactions during receiver performance testing. The process involves: a wireless signal generation module generating a simulated received signal based on first data; a receiver simulation front-end module adding simulated interference to the simulated received signal to obtain a first intermediate signal; a receiver digital front-end module sampling the first intermediate signal to obtain a second intermediate signal; a receiver digital baseband module performing baseband processing on the second intermediate signal to obtain second data; and a performance evaluation module performing performance testing on the receiver based on the first and second data.

[0086] In the receiver testing method of this application embodiment, a simulated received signal of the receiver is generated based on first data; the simulated received signal is processed by adding simulated interference factors to obtain a first intermediate signal; the first intermediate signal is sampled to obtain a second intermediate signal, the sampling rate of the second intermediate signal matching the sampling rate required for baseband processing; the second intermediate signal is processed by baseband processing to obtain second data extracted from the second intermediate signal; and the receiver is tested for performance based on the first data and the second data. The simulated interference factor addition processing belongs to the processing function of the receiver's analog front-end module, the sampling processing belongs to the processing function of the receiver's digital front-end module, and the baseband processing belongs to the processing function of the receiver's digital baseband module. This application uses a joint dynamic modeling approach involving the receiver's analog front-end module, digital front-end module, and digital baseband module to perform performance simulation testing and evaluation of the receiver. This approach integrates the main functional parts and influencing factors of the receiver, simulating the overall processing process of the receiver under dynamic air interface wireless signal reception, obtaining performance evaluation results that more closely resemble actual test performance, and thus identifying performance problems of the integrated solution after combining the analog front-end module, digital front-end module, and digital baseband module solutions as early as possible.

[0087] Based on the above embodiments, Figure 3 A flowchart illustrating another receiver testing method provided in this application embodiment is shown below. Figure 3 As shown, the method includes the following steps:

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

[0089] The explanations and descriptions in the aforementioned embodiments also apply to step 201, and the principle is the same, so they will not be repeated here.

[0090] Step 302: Perform simulated interference factor addition processing on at least one sub-signal in the simulated received signal to obtain the 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 as being composed of sub-signals, and the processing of simulated interference factors is performed on the sub-signals.

[0092] In one implementation of this application, simulated interference factors are added to some or all of the sub-signals in the simulated received signal to obtain a first intermediate signal.

[0093] In this embodiment of the application, for any target sub-signal in the simulated received signal, the target analog gain parameter of the reference sub-signal is obtained, wherein the reference sub-signal is the sub-signal in the simulated received signal whose timing is before the target sub-signal; based on the target analog gain parameter, the target interference factor parameter of the target analog interference factor related to the analog gain intensity is determined; based on the target interference factor parameter, the target sub-signal is subjected to analog interference factor addition processing to obtain the 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 other than the first sub-signal, and the reference sub-signal may refer to the sub-signal preceding the target sub-signal.

[0095] In addition to the first intermediate sub-signal, the sub-signal also has a corresponding 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 by the first intermediate sub-signal corresponding to the reference sub-signal.

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

[0097] In another implementation of this application, the target interference factor parameter that matches the target simulated gain parameter is queried based on the mapping relationship between the simulated gain parameter and the interference factor parameter corresponding to the target simulated interference factor.

[0098] For any target simulated interference factor related to the simulated gain intensity, there is a corresponding interference factor parameter table. 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 simulated gain strength, the interference factor parameter corresponding to the simulated interference factor can be a set value.

[0100] In one implementation of this application, before adding simulated interference factors to the simulated received signal, the simulated received signal can be frequency adjusted, and then the frequency-adjusted simulated received signal can be added to obtain a first intermediate signal. Alternatively, after adding simulated interference factors to the simulated received signal, the frequency can be adjusted to obtain the first intermediate signal.

[0101] Among these processes, frequency adjustment and simulated interference addition can be performed on sub-signals.

[0102] The frequency adjustment process includes adjusting the signal frequency based on the target simulated frequency parameters, which are determined based on the baseband frequency offset measured for the second intermediate sub-signal corresponding to the reference sub-signal.

[0103] In one implementation of this application, after adding simulated interference factors to the simulated received signal, the simulated received signal with added simulated interference factors can be subjected to analog-to-digital converter (ADC) processing, that is, the simulated received signal with added simulated interference factors is quantized to convert the wireless analog signal into a wireless digital signal. It should be noted that the first intermediate signal obtained after ADC processing is a high sampling rate digital signal.

[0104] like Figure 4 As shown, Figure 4 This diagram illustrates the module interaction of the front-end module in handling frequency adjustment, simulated interference addition, and ADC processing of 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 parameters. N simulated interference addition modules add simulated interference to the frequency-adjusted target sub-signal. The ADC module performs analog-to-digital conversion on the target sub-signal after adding simulated interference to obtain the first intermediate sub-signal corresponding to the target sub-signal. Here, N is greater than or equal to 1.

[0105] like Figure 5 As shown, Figure 5 This is a schematic diagram of the simulation factor module. Taking simulation factor module x as an example, this module is used to add 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 were calculated or tested by RF R&D personnel based on the selection parameters of analog devices before modeling, and have practical significance. Since the strength of the received signal changes dynamically, the analog factor module selects the corresponding interference factor parameters to add simulated interference factors according to the changes in the analog gain parameters. Taking DC leakage addition as an example, different analog gain parameters correspond to different DC leakage amplitude values. Based on this, this application more closely reflects the processing status of the analog front-end during actual signal reception and provides a more realistic evaluation effect.

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

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

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

[0110] The explanations and descriptions in the foregoing embodiments also apply to steps 303-304, as the principle is the same, and will not be repeated here.

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

[0112] Based on the above embodiments, Figure 6 A flowchart illustrating another receiver testing method provided in this application embodiment is shown below. Figure 6 As shown, the method includes the following steps:

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

[0114] Step 602: Perform simulated interference factor addition processing on the simulated received signal to obtain the first intermediate signal.

[0115] Steps 601 to 602 can be referred to the relevant explanations in the foregoing embodiments, as the principle is the same, and will not be repeated here.

[0116] Step 603: Preprocess the first intermediate signal before sampling processing, so that the signal obtained after preprocessing is used as the first intermediate signal to be sampled. The preprocessing includes at least one of compensation processing and signal adjustment processing.

[0117] In step 602, the effects of simulated interference factors are added to the simulated received signal. Therefore, this step requires compensation processing for some of the simulated interference factors.

[0118] In the embodiments of this application, the compensation processing includes compensation for DC leakage, compensation for IQ imbalance, and compensation for uneven frequency response of analog filters.

[0119] In this embodiment of the 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: Sample the first intermediate signal, and then post-process the sampled first intermediate signal to use the post-processed signal as the second intermediate signal. The post-processing includes at least one of compensation processing and signal adjustment processing.

[0121] It should be noted that steps 603 and 604 are related by AND / OR, and this embodiment shows the case where steps 603 and 604 are executed simultaneously.

[0122] As can be seen from steps 603 and 604, this application does not limit the order of sampling processing, compensation processing and signal adjustment processing.

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

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

[0125] In the receiver testing method of this application embodiment, a simulated received signal of the receiver is generated based on first data; the simulated received signal is processed by adding simulated interference factors to obtain a first intermediate signal; the first intermediate signal before sampling processing is preprocessed so that the signal obtained after preprocessing is used 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 sampled first intermediate signal is post-processed so that the signal obtained after post-processing is used as a 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 performance is tested based on the first data and the second data. The compensation processing and signal adjustment processing in this application enable the receiver performance evaluation to be closer to the actual evaluation effect, resulting in higher accuracy in performance evaluation.

[0126] Based on the above embodiments, Figure 7 A flowchart illustrating another receiver testing method provided in this application embodiment is shown below. Figure 7 As shown, the method includes the following steps:

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

[0128] Step 702: For any target sub-signal in the simulated received signal, obtain the target simulated gain parameter of the reference sub-signal; based on the target simulated gain parameter, determine the target interference factor parameter of the target simulated interference factor related to the simulated gain strength; based on the target interference factor parameter, perform simulated 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] Steps 701 to 702 can be referred to the relevant explanations in the foregoing embodiments, as the principle is the same, and will not be repeated here.

[0130] Step 703: Preprocess the first intermediate sub-signal before sampling processing, so that the preprocessed signal is used as the first intermediate sub-signal to be sampled.

[0131] Step 704: Sample the first intermediate sub-signal, and then post-process the sampled first intermediate sub-signal to use the post-processed signal as the second intermediate sub-signal corresponding to the target sub-signal in the second intermediate signal.

[0132] The preprocessing in step 703 includes compensation processing, and the postprocessing in step 704 includes compensation processing based on the target compensation parameters corresponding to the target simulated interference factors related to the simulated gain strength. The target compensation parameters are determined by querying the mapping relationship between the simulated gain parameters and compensation parameters corresponding to the target simulated interference factors based on the target simulated gain parameters of the reference sub-signal. The reference sub-signal is the sub-signal in the simulated received signal whose timing is ahead of the target sub-signal.

[0133] For any target simulated interference factor related to the simulated gain intensity, there is a corresponding compensation parameter table. The compensation parameter table is used to store the mapping relationship between the simulated gain parameters and the compensation parameters.

[0134] It should be noted that the compensation parameters in the compensation parameter table were calculated by RF R&D personnel using a calibration scheme based on the analog device factor parameters before modeling, and thus possess the error characteristics of actual calibration results. The analog factor compensation module selects the corresponding compensation parameters to compensate the signal according to the changes in the analog gain parameters. Therefore, this application more closely reflects the processing situation of the digital front end during actual signal reception, and the compensation parameters used are error-prone results obtained from calibration calculations, which provides better performance in actual evaluation. 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 during modeling; their compensation parameter tables only contain values ​​unrelated to gain, which can be directly used for performance evaluation.

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

[0136] The preprocessing in step 703 includes signal adjustment processing, and the postprocessing in step 704 includes signal adjustment processing, including signal frequency domain offset based on target frequency domain offset; wherein, the target frequency domain offset is determined based on the baseband frequency domain offset measured for the second intermediate sub-signal corresponding to the reference sub-signal.

[0137] The preprocessing in step 703 includes signal adjustment processing, and the postprocessing in step 704 includes signal adjustment processing, including signal time domain offset based on target time domain offset; wherein, the target time domain offset is determined based on the baseband time domain offset measured for the second intermediate sub-signal corresponding to the reference sub-signal.

[0138] The preprocessing in step 703 includes signal adjustment processing, and the postprocessing in step 704 includes signal adjustment processing, including signal amplitude adjustment based on target digital gain parameters; wherein, the target digital gain parameters are 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 This diagram illustrates the module interaction of the digital front-end module in performing sampling, compensation, and signal adjustment processing on the simulated received signal. It should be noted that this application does not impose any restrictions on the order of the downsampling processing module, analog factor compensation module, frequency domain offset adjustment module, time domain offset adjustment module, and amplitude adjustment module. The number of downsampling processing modules, P, is greater than or equal to 1, and the number of analog factor compensation modules, M, is greater than or equal to 1.

[0140] in addition, Figure 8 It also includes a power calculation module, which is used to calculate the digital front-end power of the signal input to the digital front-end module, that is, the first signal power.

[0141] like Figure 9 As shown, Figure 9 This is a schematic diagram of the simulation factor compensation module. Taking the target simulated interference factor x as an example, for the target sub-signal, based on the target simulated gain parameter of the reference sub-signal, the target compensation parameter is selected from the compensation parameter table, and then compensation processing is performed based on the target compensation parameter.

[0142] Step 705: Perform baseband processing on at least one of the second intermediate sub-signals in the second intermediate signal to obtain the second data.

[0143] like Figure 10 As shown, Figure 10 This is a schematic diagram of the digital baseband module's processing. The input of the digital baseband module is the low-sampling-rate digital signal output by the digital front-end module, and the output is the digital baseband power (second signal power) corresponding to the signal, the baseband time-domain offset, the baseband frequency-domain offset, and the data extracted from the low-sampling-rate digital signal (digital baseband result).

[0144] It should be noted that the digital baseband power, baseband time-domain offset, and baseband frequency-domain offset of each sub-signal in the simulated received signal may be different. In other words, these parameters change dynamically during the reception of the simulated received signal.
