Embodiment 1

[0071] Considering that the existing voltage regulation technology will cause the transmitter to fail to work normally and cannot be applied to multi-standard base station products after the power amplifier is adjusted, this embodiment provides a new voltage regulation method, which performs power amplification according to the change of the peak power. The adaptation of the working voltage makes the power amplifier work at the saturated power point, which effectively reduces the power consumption of the power amplifier; figure 1 As shown, this embodiment provides a power amplifier voltage regulation method, which is applied to a multi-standard base station, and includes the following steps:

[0072] Step 101: Obtain the average power and peak-to-average ratio of the transmitted signal.

[0073] The timing of the two processes of obtaining the average power and the peak-to-average ratio in this step can be any, and can be simultaneously or sequentially.

[0074] Specifically,...

Embodiment 2

[0106]When the number of users and services carried by the base station increases, the transmit power will increase. In order to avoid affecting the coverage and performance of the base station, it is necessary to rapidly increase the operating voltage of the power amplifier to increase the linear range of the power amplifier. Therefore, the increase in voltage requires a quick response, which is definitely necessary in engineering applications. The faster the better, but the actual switching frequency is limited by the technical limitations of the power module. At present, the power module for mobile base stations in the industry can achieve a boost response of hundreds of milliseconds, so the general transmission power judgment cycle is hundreds of milliseconds. Once the voltage level corresponding to the transmission power is found to be higher than the current voltage, it needs to be boosted. operate.

Embodiment 3

[0119] In order to ensure the normal transmission of services, the peak power input to the power amplifier must not exceed the saturation power corresponding to the target potential during the voltage regulation process of the power amplifier. Therefore, on the basis of the first and second embodiments above, this embodiment provides a The method for adjusting the power amplifier voltage may further include: before adjusting (increasing or decreasing) the operating voltage of the power amplifier, adjusting the peak power of the transmitted signal so that it is less than or equal to the saturation power corresponding to the target operating voltage. Specifically, after obtaining the target operating voltage, before increasing or decreasing the operating voltage of the power amplifier according to the target operating voltage, it also includes: adjusting the peak power of the transmitted signal to make it less than or equal to the saturation corresponding to the target operating v...

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a power amplifier voltage regulation method and device. Background technique [0002] With the surge of data traffic and the rapid expansion of network scale, telecom operators are under increasing pressure to save energy and reduce emissions. According to statistics, the annual power consumption of a traditional base station is as high as 15,000 kWh. Therefore, how to reduce the energy consumption of base station operations has become an issue that operators are increasingly concerned about. As the most important part of the mobile communication network, mobile base stations account for 90% of energy consumption. Therefore, the energy-saving design of mobile base stations has become the most important and key factor for energy-saving and emission reduction of mobile networks. important direction of force. [0003] The power amplifier is a high-power transmission module ...
