[0031] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should fall within the protection scope of the present application.

[0032] It should be noted that the terms "first," "second," etc., used in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Example 1

[0034] In recent years, with the full deployment of 5G networks, technologies such as industrial digitalization and the Internet of Things have flourished. The design of increasingly miniaturized MIMO terminal products is increasingly geared towards industrial applications. However, most traditional communication technology companies only provide basic communication networking modules; the final terminal's product form, deployment environment, and application characteristics are all driven by industry applications. The main typical terminals can be divided into the following three categories:

[0035] (1) Widely connected, small data, low-cost data collection terminals: typical deployments are smart water meters, smart electricity meters, and smart homes;

[0036] (2) Mobile, real-time tracking, and data-frequent positioning and tracking terminals: Typical deployments include digital logistics systems, underground safety, and agricultural and fishery tracking.

[0037] (3) High-speed transmission: A typical deployment is a high-definition camera and a live broadcast camera.

[0038] As can be seen from the above, traditional communication modules are gradually becoming mere conduits, and thus de-emphasized in application. More and more application industries, supported by these "conduit" technologies, are taking center stage in industrial digitalization. Against this backdrop of the convergence of traditional communications and emerging digital industries, the issues of testing and certification methods and solutions for new terminals, especially the complexity of MIMO terminal testing, have emerged and urgently need to be addressed.

[0039] To address the aforementioned issues, current mainstream solutions fall into two main categories, and the testing methods for these two mainstream solutions will be briefly described below.

[0040] (1) MIMO terminal authentication scheme

[0041] The wireless terminal MIMO OTA (Over The Air) test site conditions, measurement parameters and measurement methods are respectively formulated according to requirements, so as to be fully compatible with the requirements of national standards. Figure 1 is a structural schematic diagram of an optional antenna terminal performance test system of the related art.

[0042] The test system includes a full-wave anechoic chamber, and the full-wave anechoic chamber contains a multi-probe system for measuring MIMO OTA performance, such as a channel simulator, a wideband wireless communication tester, a network analyzer, a test turntable and its controller, and professional test software. In addition, a radio frequency system and a control system for measurement are also included. The experimental test values are processed and archived by a computer for data acquisition, and the data and results can be analyzed in real time.

[0043] However, the disadvantages of this scheme are: high investment cost; high construction environment demand, requiring a fixed dedicated laboratory; long construction period; for Internet of Things terminals, the investment amount and investment cycle cost of this scheme are less than one quarter of the market total amount of product iteration period.

[0044] (2) Terminal application test scheme

[0045] The reverberation chamber test technology is briefly described for such a scheme. Figure 2 is a structural schematic diagram of an optional reverberation chamber system of the related art. The main working principle of the reverberation chamber test scheme is also to initiate a direct communication process of the to-be-tested device by the base station simulator. At the same time, the stirrer, turntable and antenna in the reverberation chamber shell are constantly stirred, rotated and switched, respectively, to form full traversal of various space scenes. Finally, the host computer statistical software obtains the statistical results of the traversal test. The test certification process is completed.

[0046] However, the disadvantages of this scheme are: the comparability of test accuracy and repeatability between different systems is insufficient, because it cannot be widely deployed and certified as an industry scheme.

[0047] To solve the above problems, the embodiments of the present application provide a multi-antenna terminal performance test system, Figure 3 is a structural diagram of an optional multi-antenna terminal performance test system according to the embodiments of the present application, as shown in Figure 3 The system includes a channel transmission test platform 32 and an amplitude and phase device 34, wherein:

[0048] The channel transmission test platform 32 is used to acquire the antenna pattern information of the multiple antennas of the multiple antenna terminal, wherein the antenna pattern information comprises amplitude and phase; acquire a test signal and determine a first matrix of the multiple antenna terminal based on the test signal; and determine a correction matrix based on the antenna pattern information, wherein the correction matrix is used to normalize the first matrix to obtain a standard matrix.

[0049] The channel transmission test platform 32 further comprises a base station simulator 321, a channel simulator 322 and a multiple antenna terminal 323.

[0050] The amplitude and phase device 34 is used to adjust the channel transmission test platform based on the standard matrix.

[0051] Further, after the amplitude and phase device 34 adjusts the channel transmission test platform based on the standard matrix, the multiple antenna terminal can be tested for performance by the adjusted channel transmission test platform 32.

[0052] In the performance test system of the multiple antenna terminal, a more detailed performance test method of the multiple antenna terminal is further provided, and the present application will be described in detail.

[0053] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0054] Figure 4 is a flow diagram of an optional performance test method of a multiple antenna terminal according to an embodiment of the present application, as shown in Figure 4 The method comprises steps S402-S408, wherein:

[0055] In step S402, the antenna pattern information of the multiple antennas of the multiple antenna terminal is acquired, wherein the antenna pattern information comprises amplitude and phase.

[0056] In the technical solution provided in step S402 of the present application, the multiple antenna terminal is a MIMO wireless terminal. In actual applications, it is usually impossible to destroy the multiple antenna terminal to be tested and open the antenna port, so the multiple antenna terminal can be placed in a microwave darkroom to shield the environment and remove noise and interference factors. Therefore, in the present application, the antenna pattern information of the multiple antennas of the multiple antenna terminal is one of the performances of the multiple antennas of the multiple antenna terminal placed in the microwave darkroom.

[0057] Optionally, the measurement of the antenna pattern information of the antennas of the multi-antenna terminal can be realized by an air interface test system. In addition, the number of the antennas measured in the microwave darkroom is greater than or equal to the number of the antennas of the multi-antenna terminal.

[0058] Specifically, the air interface test is to establish a reflection-free free space by using an anechoic chamber to eliminate unwanted reflections of the electric wave. The test signal transmitted by the base station simulator passes through a predefined channel model of the channel emulator (CE) to generate a test transmission information, which is propagated to the dual-polarized antenna (i.e., multi-probe) at the center of the device under test (DUT) through space radiation, and the throughput of the device under test in the signal fading process is recorded to evaluate the wireless performance of the antenna of the device under test.

[0059] In addition, the multi-antenna terminal can have multiple placement states, such as free space, close to a simulated human head, handheld, etc. In actual application, any one of the placement states or the antenna patterns of the multiple antennas of the multi-antenna terminal in each placement state can be tested according to user demand.

[0060] As an optional implementation, before the antenna pattern information of the multiple antennas of the multi-antenna terminal is acquired in the technical solution provided in the above step S402 of the present application, a channel transmission test platform can also be set, wherein the channel transmission test platform comprises a base station simulator, a channel simulator, and a multi-antenna terminal.

[0061] In addition, the channel transmission test platform can further comprise a comprehensive tester, a microwave darkroom, etc.

[0062] Specifically, Figure 5 is a structural schematic diagram of an optional channel transmission test platform according to an embodiment of the present application, wherein the channel transmission test platform is 2*2-MIMO, i.e., the number of the transmitting antennas and the receiving antennas is both two, the channel simulator is 2-channel-in and 4-channel-out, the comprehensive tester is 2-channel, the microwave darkroom contains 2 test antennas (circularly polarized antenna terminals and corresponding cables and polarization combiners), and the DUT terminal is a multi-antenna terminal.

[0063] The channel simulator is set to 4-channel-out, and specifically, it can be combined by 1 / 3 and 2 / 4 respectively, and then output to the circularly polarized antenna terminals in the microwave darkroom through 2 paths.

[0064] Optionally, the signal transmitted by the transmitting antenna of the base station simulator comprises a first test signal and a second test signal, and the receiving signal of the multi-antenna terminal in the microwave darkroom comprises a first receiving signal and a second receiving signal.

[0065] Step S404: Obtain the test signal and determine the first matrix of the multi-antenna terminal based on the test signal.

[0066] As an optional implementation, in the technical solution provided by step S404 of the present invention, the method includes: determining a first test transmission signal generated by a channel simulator through a first test signal; and determining a second test transmission signal generated by a channel simulator through a second test signal.

[0067] Specifically, such as Figure 5 The channel transmission test platform shown uses a base station simulator to transmit a first test signal x1(f,t) and a second test signal x2(f,t). The first and second test signals x1(f,t) are then transmitted through the channel simulator. Since the channel simulator has 2 inputs and 4 outputs, the first test signal x1(f,t) is transmitted through the simulator to obtain a first test transmission signal s1(f,t), and a first wireless cable transmission is established from the first test transmission signal s1(f,t) to the first received signal y1(f,t). Simultaneously, the second test signal is transmitted through the channel simulator to obtain a second test transmission signal s2(f,t), and a second wireless cable transmission is established from the second test transmission signal s2(f,t) to the second received signal y2(f,t).

[0068] Furthermore, after determining the first received signal y1(f,t) and the second received signal y2(f,t), the first matrix of the multi-antenna terminal receiving test signals can be further determined. Therefore, the first matrix can be represented as:

[0069]

[0070] In addition, since the first matrix y of the test signal received by the multi-antenna terminal is a complex matrix, the analysis of the terminal performance test is quite difficult. Therefore, the first matrix can be normalized in step S406 to reduce the difficulty of performance testing.

[0071] Step S406: Determine the correction matrix based on the antenna pattern information. The correction matrix is ​​used to normalize the first matrix to obtain the standard matrix.

[0072] As an optional implementation method, combined with Figure 5 The channel transmission test platform shown is illustrated, and the construction of the correction matrix is ​​explained through steps S4061-S4065, wherein:

[0073] Step S4061: Obtain any first amplitude from the antenna radiation pattern information, and determine a first value and a second value based on the first amplitude.

[0074] Any first amplitude c1 can be selected from the acquired multiple antenna pattern information of the multi-antenna terminal, wherein the first amplitude c1 can also be set according to the best sensitivity of the channel transmission test platform.

[0075] Specifically, the first radio cable transmission of the first test signal s1(f, t) to the first received signal y1(f, t) can be established in the following manner: the output ports of the channel simulator respectively transmit s1(f, t) and w1s1(f, t) (i.e., port 1 and port 2 of the channel simulator), and the output ports of the channel simulator transmit s2(f, t) and w2s2(f, t) (i.e., port 3 and port 4 of the channel simulator) are closed, so as to set the first amplitude c1 to a value that can provide a good signal for the ports of the multi-antenna terminal. At this time, the RSRP (Reference Signal Receiving Power) of the signals received by the two receiving antennas of the multi-antenna terminal is respectively:

[0076] RS1P1(w1) = |c1| 2 |b 11 | 2 P(x1)

[0077] RSRP2(w1) = |c1| 2 |b 21 | 2 P(x1)

[0078] RSRP1(w1) and RSRP2(w1) respectively represent the reference signal receiving power of the test signal received by each receiving antenna when the first test signal x1(f, t) is transmitted to the two receiving antennas of the multi-antenna terminal. And P(x1) is the average power of the first test signal x1(f, t).

[0079] In addition, the first value b 11 and the second value b 21 are respectively:

[0080] b 11 = c1(a 11 -w1a 12 )

[0081] b 21 = c1(a 21 +w1a 22 )

[0082] wherein a ij is the path complex gain from the jth transmitting antenna to the ith receiving antenna.

[0083] Step S4062, obtaining any first phase in the antenna pattern information, and determining a first target amplitude based on the first phase, wherein the first phase is taken as an amplitude value of the first target amplitude, and a phase value of the first target amplitude is a third value.

[0084] Optionally, the first target amplitude can be determined in the following manner: fixing the first phase, and polling the third value in a first range to determine a third target value that minimizes the first effective received power, wherein the first effective received power is determined by the first amplitude, the fourth value and the first effective transmitted power; fixing the third target value, and polling the first phase in a second range to determine a first target phase that minimizes the first effective received power; determining the first target amplitude based on the first target phase and the third target value.

[0085] Specifically, the first target amplitude can be denoted as w1, and

[0086] First, fixing the first phase a1 of w1, polling the third value between [0°, 360°], and constantly recording the value change of the first effective received power RSRP2(w1), wherein when the phase difference between a 21 and a 22 is 180°, the a that minimizes the first effective received power RSRP2(w1) can be obtained, and denoted as the third target value, and denoted as

[0087] Then, fixing the third target value polling the first phase a1 in a suitable range, and constantly recording the value change of the first effective received power RSRP2(w1), wherein when the phase difference between a 11 and a 12 is 180° and the amplitudes are equal, the a that minimizes the first effective received power RSRP2(w1) can be obtained, and denoted as wherein the smaller the RSRP2(w1) is, the smaller the interference influence between the two receiving antennas of the multi-antenna terminal is.

[0088] Finally, the first target amplitude w1 can be written as:

[0089] Similarly, the first target amplitude w2 can be determined according to the above steps S4061-S4062.

[0090] Step S4063, obtaining any second amplitude in the antenna pattern information, and determining a fourth value and a fifth value based on the second amplitude.

[0091] Any second amplitude c2 can be selected from the acquired multiple antenna pattern information of the multi-antenna terminal, wherein the second amplitude c2 can also be set according to the best sensitivity of the channel transmission test platform.

[0092] Specifically, the first radio cable transmission of the second test transmitting signal s2(f, t) to the second receiving signal y2(f, t) can be established in the following manner: the output ports of the channel simulator respectively transmit s2(f, t) and w2s2(f, t) (i.e. the port 3 and the port 4 of the channel simulator), and the output ports of the channel simulator transmit s1(f, t) and w1s1(f, t) (i.e. the port 1 and the port 2 of the channel simulator) are closed, so that the second amplitude c2 is set to a value that can provide a good signal for the ports of the multi-antenna terminal. At this time, the RSRP of the signals received by the two receiving antennas of the multi-antenna terminal is respectively:

[0093] RSRP2(w2) = |c2| 2 |b 22 | 2 P(x2)

[0094] RSRP1(w2) = |c2| 2 |b 12 | 2 P(x2)

[0095] wherein RSRP2(w2) and RSRP2(w1) respectively represent the reference signal received power of the test signal received by each receiving antenna when the second test signal x2(f, t) is transmitted to the two receiving antennas of the multi-antenna terminal, and P(x2) is the average power of the second test signal x2(f, t).

[0096] In addition, the first value b 22 and the second value b 12 are respectively:

[0097] b 22 = c2(a 11 +w1a 12 )

[0098] b 12 = c2(a 21 +w1a 22 )

[0099] wherein a ij is the path complex gain from the jth transmitting antenna to the ith receiving antenna.

[0100] Step S4064, obtaining any second phase in the antenna pattern information, and determining a second target amplitude based on the second phase, wherein the second phase is taken as an amplitude value of the second target amplitude, and a phase value of the second target amplitude is a sixth numerical value.

[0101] Optionally, the second target amplitude can be determined in the following manner: fixing the second phase, and polling the sixth numerical value in the first range to determine a sixth target numerical value that minimizes the second effective receiving power, wherein the second effective receiving power is determined by the second amplitude, the fifth numerical value and the second effective transmitting power; fixing the sixth target numerical value, and polling the second phase in the third range to determine a second target phase that minimizes the second effective receiving power; determining the second target amplitude based on the second target phase and the sixth target numerical value.

[0102] Specifically, the second target amplitude can be denoted as w2, and

[0103] First, fixing the second phase a2 of w2, polling the sixth numerical value polling between [0°, 360°] and constantly recording the numerical change of the second effective receiving power RSRP1(w2), wherein when a 11 and a 12 the phase difference between a and a is 180°, the a that minimizes the second effective receiving power RSRP1(w2) can be obtained, and denoted as the second target phase a2. is the sixth target numerical value, and denoted as

[0104] Then, fixing the sixth target numerical value polling in a suitable range of the second phase a2, and constantly recording the numerical change of the second effective receiving power RSRP1(w2), wherein when a 21 and a 22 the phase difference between a and a is 180° and the amplitudes are equal, the a that minimizes the second effective receiving power RSRP1(w2) can be obtained, and denoted as the second target phase a2. wherein the smaller the RSRP1(w2) is, the smaller the interference influence between the two receiving antennas of the multi-antenna terminal is

[0105] Finally, the second target amplitude w2 can be written as:

[0106] Step S4065, determining the correction matrix based on the first amplitude, the first target amplitude and the first test transmitting signal, and the second amplitude, the second target amplitude and the second test transmitting signal.

[0107] Specifically, the correction matrix can be denoted as G, and its expression can be written as:

[0108]

[0109] Further, after determining the G matrix, the isolation levels of each receiving antenna of the multi-antenna terminal can also be determined by the following formula:

[0110]

[0111]

[0112] Wherein, the smaller RSRP2(w1), RSRP1(w2) are, the higher the isolation levels of I1, I2 are, which means the stronger the ability of the corresponding receiving antenna to isolate the interference signal.

[0113] Since the ability of each receiving antenna to receive the test signal is the same, and there is cable loss in the transmission process, it is necessary to ensure that the propagation coefficients of the direct link (i.e. b 11 and b 22 ) are balanced. Therefore, after determining the correction matrix based on the antenna pattern information, a third effective receiving power can be determined based on the first amplitude, the first value and the first effective transmitting power; a fourth effective receiving power can be determined based on the second amplitude, the fifth value and the second effective transmitting power; when the third effective receiving power and the fourth effective receiving power are equal, it is determined that the first matrix is normalized by the correction matrix to obtain a standard matrix.

[0114] Wherein, the third effective receiving power is denoted as RSRP1(w1), the fourth effective receiving power is denoted as RSRP2(w2), and when RSRP1(w1) and RSRP2(w2) are approximately equal, the above-mentioned G matrix is determined as the correction matrix, and the standard matrix is obtained by normalizing the first matrix by the correction matrix.

[0115] As an optional implementation, after determining the correction matrix based on the antenna pattern information, the coherence bandwidth can also be verified to confirm whether the frequency band is flat within the frequency band.

[0116] Optionally, the antenna pattern information of the multiple antennas of the multi-antenna terminal is sequentially collected according to a first frequency range within the target frequency band to obtain an antenna pattern set; the correlation coefficient of the target antenna corresponding to the adjacent antenna pattern information in the antenna pattern set is determined by polling the antenna pattern set; when the correlation coefficient exceeds a first preset threshold, it is determined that the target frequency band is flat.

[0117] Wherein, the first preset threshold can be selected as 0.8, and the value of the first preset threshold is not limited here, and can be set in combination with the actual application scenario.

[0118] As another alternative implementation, after the correction matrix is determined according to the antenna pattern information, the correction matrix, i.e., the G matrix, can be repeatedly verified, so as to avoid the influence of the slight test operation on the accuracy of the final test platform.

[0119] Optionally, the correction matrix is repeatedly searched on the time and / or space variable, and the repeatability influence factor is determined.

[0120] The repeatability influence factor is used to affect the repeatability of the correction matrix, and the repeatability of the correction matrix is improved based on the repeatability influence factor.

[0121] In step S408, the channel transmission test platform is adjusted based on the standard matrix, and the performance of the multi-antenna terminal is tested through the adjusted channel transmission test platform.

[0122] Specifically, the channel transmission test platform is adjusted by using the amplitude-phase device according to the standard matrix, and the performance of the multi-antenna terminal is tested through the adjusted channel transmission test platform, wherein the amplitude-phase device can be a 2*2 channel radio frequency switch box, and each channel of the radio frequency switch box is composed of 1 programmable amplitude changer and 1 programmable phase changer.

[0130] According to the embodiment of the present application, a performance testing device of a multi-antenna terminal for implementing the performance testing method of the multi-antenna terminal is further provided, Figure 6 is a structural schematic diagram of an optional performance testing device of a multi-antenna terminal according to the embodiment of the present application, as Figure 6 shown, the performance testing device of the multi-antenna terminal at least includes an acquisition module 61, a first determination module 62, a second determination module 63 and a testing module 64, wherein:

[0131] The acquisition module 61 is configured to acquire antenna pattern information of multiple antennas of the multi-antenna terminal, wherein the antenna pattern information includes amplitude and phase.

[0132] Specifically, the multi-antenna terminal is a MIMO wireless terminal. Generally, it is impossible to destroy the multi-antenna terminal to be tested to open the antenna port in actual application, so the multi-antenna terminal can be placed in a microwave darkroom to shield the environment to remove noise and interference factors. Therefore, the antenna pattern information of the multiple antennas of the multi-antenna terminal acquired in the embodiment of the present application is one of the performances of the multiple antennas of the multi-antenna terminal placed in the microwave darkroom.

[0133] Optionally, the acquisition module 61 can measure the antenna pattern information of the antennas of the multi-antenna terminal through an air interface test system. In addition, the number of the antennas measured in the microwave darkroom is greater than or equal to the number of the antennas of the multi-antenna terminal.

[0137] Optionally, the signals transmitted by the transmitting antenna of the base station simulator include: a first test signal and a second test signal, and the signals received by the multi-antenna terminal in the microwave anechoic chamber include: a first receiving signal and a second receiving signal.

[0138] As an optional implementation, the first determining module 62 can also determine the first test transmission signal generated by the first test signal through the channel simulator; and determine the second test transmission signal generated by the second test signal through the channel simulator.

[0139] Specifically, such as Figure 5 The channel transmission test platform shown uses a base station simulator to transmit a first test signal x1(f,t) and a second test signal x2(f,t). The first and second test signals x1(f,t) are then transmitted through the channel simulator. Since the channel simulator has 2 inputs and 4 outputs, the first test signal x1(f,t) is transmitted through the simulator to obtain a first test transmission signal s1(f,t), and a first wireless cable transmission is established from the first test transmission signal s1(f,t) to the first received signal y1(f,t). Simultaneously, the second test signal x2(f,t) is transmitted through the channel simulator to obtain a second test transmission signal s2(f,t), and a second wireless cable transmission is established from the second test transmission signal s2(f,t) to the second received signal y2(f,t).

[0140] Furthermore, the first determining module 62 can determine a first matrix of the test signals received by the multi-antenna terminal based on the test signals. Therefore, the first matrix can be represented as:

[0141]

[0142] The second determining module 63 is used to determine the correction matrix based on the antenna pattern information, wherein the correction matrix is ​​used to normalize the first matrix to obtain a standard matrix.

[0143] As an optional implementation, the second determining module 63 can determine the correction matrix in the following manner: determining the correction matrix according to the antenna pattern information, comprising: obtaining any first amplitude in the antenna pattern information, and determining a first value and a second value based on the first amplitude; obtaining any first phase in the antenna pattern information, and determining a first target amplitude based on the first phase, wherein the first phase is taken as the amplitude value of the first target amplitude, and the phase value of the first target amplitude is a third value; obtaining any second amplitude in the antenna pattern information, and determining a fourth value and a fifth value based on the second amplitude; obtaining any second phase in the antenna pattern information, and determining a second target amplitude based on the second phase, wherein the second phase is taken as the amplitude value of the second target amplitude, and the phase value of the second target amplitude is a sixth value; determining the correction matrix based on the first amplitude, the first target amplitude and the first test transmission signal, and the second amplitude, the second target amplitude and the second test transmission signal.

[0144] Optionally, the first target amplitude can be determined in the following manner: fixing the first phase, and polling the third value in a first range to determine a third target value that minimizes the first effective received power, wherein the first effective received power is determined by the first amplitude, the fourth value and the first effective transmission power; fixing the third target value, and polling the first phase in a second range to determine a first target phase that minimizes the first effective received power; determining the first target amplitude based on the first target phase and the third target value.

[0145] Optionally, the second target amplitude can be determined in the following manner: fixing the second phase, and polling the sixth value in a first range to determine a sixth target value that minimizes the second effective received power, wherein the second effective received power is determined by the second amplitude, the fifth value and the second effective transmission power; fixing the sixth target value, and polling the second phase in a third range to determine a second target phase that minimizes the second effective received power; determining the second target amplitude based on the second target phase and the sixth target value.

[0146] Since the ability of each receiving antenna to receive the test signal is the same, and there is cable loss in the transmission process, it is necessary to ensure that the direct link (i.e., b 11 and b 22 ) propagation coefficients are balanced. Therefore, after the antenna pattern information determines the correction matrix, the third effective received power can be determined based on the first amplitude, the first value and the first effective transmission power; the fourth effective received power can be determined based on the second amplitude, the fifth value and the second effective transmission power; when the third effective received power and the fourth effective received power are equal, it is determined that the first matrix is normalized by the correction matrix to obtain a standard matrix.

[0147] Wherein, the third effective receiving power is denoted as RSRP1(w1), the fourth effective receiving power is denoted as RSRP2(w2), and when RSRP1(w1) and RSRP2(w2) are approximately equal, the above-mentioned G matrix is determined as the correction matrix, and the standard matrix is obtained by normalizing the first matrix through the correction matrix.

[0148] As an optional implementation, after the correction matrix is determined according to the antenna pattern information, the coherence bandwidth can be verified to confirm whether the frequency band is flat.

[0149] Optionally, the antenna pattern information of the multiple antennas of the multi-antenna terminal is collected in the target frequency band according to a first frequency range to obtain an antenna pattern set; the antenna pattern set is polled to determine the correlation coefficient of the target antenna corresponding to the adjacent antenna pattern information in the antenna pattern set; and when the correlation coefficient exceeds a first preset threshold, it is determined that the target frequency band is flat.

[0150] The first preset threshold can be 0.8, and the value of the first preset threshold is not limited here, and can be set according to actual application scenarios.

[0151] As another optional implementation, after the correction matrix is determined according to the antenna pattern information, the correction matrix, i.e., the G matrix, can be repeatedly verified to avoid the influence of the small test operation on the accuracy of the final test platform.

[0152] Optionally, the correction matrix is repeatedly searched in time and / or space variables to determine a repeatability influence factor, wherein the repeatability influence factor is used to affect the repeatability of the correction matrix; and the repeatability of the correction matrix is improved based on the repeatability influence factor.

[0154] Specifically, the test module 64 first adjusts the channel transmission test platform according to the standard matrix using an amplitude-phase device, and performs performance testing on the multi-antenna terminal through the adjusted channel transmission test platform, wherein the amplitude-phase device can be a 2*2 channel radio frequency switch box, and each channel of the radio frequency switch box is composed of one programmable amplitude changer and one programmable phase changer. Thus, the performance testing on the MIMO wireless terminal can be supported without limiting the test environment, and the most accurate performance testing result can be obtained on the basis of the minimum construction cost and construction period.
