Description

CROSS-REFERENCE TO RELATED PATENT APPLICATION This application claims the benefit of priority to Taiwan Patent Application No. 113142027, filed on Nov. 4, 2024. The entire content of the above identified application is incorporated herein by reference. Some references, which may include patents, patent applications and various publications, may be cited and discussed in the description of this disclosure. The citation and/or discussion of such references is provided merely to clarify the description of the present disclosure and is not an admission that any such reference is “prior art” to the disclosure described herein. All references cited and discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference. FIELD OF THE DISCLOSURE The present disclosure relates to a technology of power compensation for a wireless communication module, and more particularly to a method for estimating power-compensation values for the wireless communication module based on association of statistical data. BACKGROUND OF THE DISCLOSURE When a wireless communication module is manufactured, the transmit power of the wireless communication module is required to be compensated and checked so as to pass factory verification. FIG. 1 is a schematic diagram illustrating a test system for the wireless communication module. In the test system, a test instrument 10 is used to generate test data 101, such as the WiFi™ or Bluetooth™ communication signals. The signals are transmitted out via a wireless communication module 100. After that, the power 103 of the wireless communication module 100 under multiple frequency bands is measured. The measured values of power 103 can be compared with values of target power for obtaining power-compensation values, i.e., a compensated power is equal to a subtracting the measured power 103 from the target power. The power-compensation values in the multiple frequency bands are then written to a memory 110 of the wireless communication module 100. The memory 110 of the wireless communication module 100 can be a one-time programmable (OTP) memory such as an electrically-erasable programmable read-only memory (EEPROM) or an eFuse. When the power-compensation values are successfully written into the memory 110, the wireless communication module 100 can be shipped from the factory and used in various electronic devices. The conventional method for calculating the compensation power for the wireless communication module is required to test and verify each of the channels; however, the verification may fail if the calculated compensation power fails to meet a specification, which means the power-compensation values are wrong. Thus, the whole processes such as adjustment, measurement, test and calculation need to be executed again, and a verification schedule for the wireless communication module will be postponed. SUMMARY OF THE DISCLOSURE In order to reduce verification time for wireless communication modules by acquiring the power-compensation values more efficiently, the present disclosure provides a method for obtaining power-compensation values with statistical data and the wireless communication module that uses the power-compensation values obtained by the method. In one aspect, in the method for obtaining power-compensation values with statistical data, statistical data of power-compensation values in multiple frequencies of the wireless communication module is obtained. One of the power-compensation values corresponding to each of the frequencies is then obtained based on data characteristics of the power-compensation values in each of the frequencies of the statistical data. Therefore, a set of power-compensation values for the wireless communication module in the multiple frequencies can be obtained and written into a memory of the wireless communication module. Main circuit components of the wireless communication module include a wireless communication circuit and the memory. The wireless communication circuit is used to transmit radio-frequency signals with a transmit power via an antenna. The memory is used to store the multiple power-compensation values in the multiple frequencies that are obtained based on the statistical data for the wireless communication module. In one further aspect of the present disclosure, the wireless communication module connects with a test platform via a connection interface. A test instrument of the test platform is used to measure the radio-frequency signals outputted by the wireless communication module via different channels under different configuration settings of ARF (Antenna-DataRate-Frequency). Further, the transmit power of the radio-frequency signals under the different configuration setting of ARF can be obtained when the multiple wireless communication modules undergo measurement and testing by the test platform. After the values of the trans
