Abstract

The invention provides a method, device and equipment for optimizing an inner loop power control index of a power amplifier and a medium. The method comprises the following steps: S1, carrying out conventional calibration on the power of the power amplifier; S2, testing an inner loop power control index of the power amplifier, judging whether the inner loop power control index of the high, mediumand low channel compensation point of the frequency band meets the 3GPP standard or not during gain switching: if so, ending the optimization process, and if not, or the allowance is small, recordingthe difference value between the inner loop power control index of the frequency band high-medium-low channel compensation point and the 3GPP standard, and executing the next step; S3, adjusting the allowance, and respectively calculating the power compensation data of the frequency band high-medium-low channel compensation point according to the difference between the inner ring power control index of each frequency band high-medium-low channel gain switching point and the 3GPP standard and the adjusted allowance; S4, after gain switching, compensating the power of the high, medium and low channel compensation points of the frequency band by using the corresponding power compensation data, and returning to the step S1 until the requirements of the 3GPP standard can be met.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, equipment and medium for optimizing the power control index of the inner loop of a power amplifier. Background technique [0002] With the development of communication technology, the market demand for mobile terminals has become greater. The requirements for indicators of communication terminals are getting higher and higher. One of the devices that has the greatest relationship with the communication terminal indicators is the power amplifier. Because the performance of the power amplifier is uneven, it is particularly important to correct the power amplifier through external compensation. [0003] At present, the power amplifier of the wideband code division multiple access system generally has three kinds of gains, which are high gain, medium gain and low gain. Gain switching points are preset on platforms such as Qualcomm, ASR or MTK on the...
