However, when the ET mode is used for power supply, the nonlinear effect of the power amplifier will be obvious when the environment changes. In order to adapt to various environmental changes, the ET mode power supply will be improved, which will cause a lot of manpower and material resources. All human and material resources are a kind of consumption
For example, a large change in temperature will have a significant impact on the parameters of the power amplifier powered by ET mode, resulting in that after the power amplifier is debugged at room temperature, when it is applied to a high temperature or low temperature environment, it will not be correct. The parameters of the power amplifier powered by the ET mode are no longer applicable, resulting in obvious deterioration of the performance of the power amplifier

The invention relates to the technical field of communication, and provides a power supply method and device of a power amplifier, a medium and a communication system. The communication system comprises a baseband processing unit, a modulation-demodulation unit, a radio frequency transceiving unit, a coupler, a power amplifier, a radio frequency front-end assembly, an antenna, an environmental parameter detection unit and a power supply unit, wherein the baseband processing unit, the modulation-demodulation unit, the radio frequency transceiving unit, the coupler, the power amplifier, the radio frequency front-end assembly and the antenna are connected in sequence; the power supply unit is connected between the modulation-demodulation unit and the power amplifier; the coupler is further connected with the modulation-demodulation unit; the coupler and the environmental parameter detection unit respectively detect the power of the power amplifier and the environmental parameter of an environment, and send the power and the environmental parameter to the modulation-demodulation unit; and the modulation-demodulation unit determines that the power supply mode of the power amplifier is an average power tracking mode or an envelope tracking mode based on the environmental parameter and the power. Thus, the power supply mode can be determined in combination with the environmental parameter, and performance deterioration is improved.
Description
