The invention discloses a transmitting power adjusting method and device based on temperature compensation, a computer readable storage medium and a transmitting power adjusting system based on temperature compensation. The method comprises the steps: acquiring the average temperature and the average dissipation power of a to-be-adjusted chip in a preset time period and the average dissipation power of an external power amplifier connected with the to-be-adjusted chip; calculating the real-time average temperature of the external power amplifier according to the average temperature and the average dissipation power of the to-be-adjusted chip and the average dissipation power of the external power amplifier; calculating a gain attenuation value of the external power amplifier according to the real-time average temperature of the external power amplifier; and adjusting the transmitting power of the to-be-adjusted chip according to the gain attenuation value of the external power amplifier. By the technical scheme, accurate temperature compensation can be conducted on the power amplifier, the problem that the deviation between the actual transmitting power and the expected transmitting power of a chip is large is solved, and the accuracy of the transmitting power is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication and power control, in particular to a temperature compensation-based transmission power adjustment method, device, computer-readable storage medium and system. Background technique [0002] In the existing open-loop PA (power amplifier, power amplifier) ​​system, since there is no power value fed back by the PA, the temperature compensation of the transmit power of the WiFi chip can only be based on the internal temperature of the WiFi chip and a set of preset temperature gradients , as the temperature of the WiFi chip changes, the transmit power at the chip end is dynamically adjusted, so as to realize the temperature compensation of the system. [0003] However, this temperature compensation mechanism does not consider the following issues: 1. The transmit power of the WiFi chip is different under different working modes, and the heat generation of the external PA is diffe...
