Problems solved by technology

[0005] In the prior art, it is necessary to pre-set the environment / frequency band before the wireless terminal leaves the factory, and set matching matching parameters for the set environment / frequency band; however, in practical applications, the environment and frequency band where the terminal is located change , the preset matching parameters cannot make accurate adjustments to the impedance of the matching network, which affects the working state of the antenna

Abstract

The embodiment of the invention relates to a matching parameter processing method and a mobile terminal. The method comprises the following steps: a transmission circuit generates an incident wave signal; a directional coupler divides the incident wave signal into two incident wave signals, wherein one incident wave signal is subjected to coupling processing to generate an incident wave coupling signal, and the other incident wave signal is transmitted to an antenna through a matching network circuit; when the impedance of the antenna is not matched with the impedance of the matching network circuit, the directional coupler receives a reflected wave signal fed back by the antenna, and the reflected wave signal is subjected to coupling processing to generate a reflected wave coupling signal; a comparator obtains comparison parameters of the reflected wave coupling signal corresponding to a preset reflection threshold value and the incident wave coupling signal according to the reflected wave coupling signal and the incident wave coupling signal; a processor determines matching parameters according to the comparison parameters; the matching network circuit regulates the impedance of the matching network circuit according to the matching parameters. As a result, the impedance of the matching network circuit is regulated dynamically, and the performance of the antenna is optimized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for processing matching parameters and a mobile terminal. Background technique [0002] As the use scenarios of wireless terminals become more and more diverse, antennas of wireless terminals must be applicable to various frequency bands and various complex and random scenarios. [0003] In the prior art, various types of sensors are added inside the wireless terminal to detect the current environment or frequency band of the wireless terminal through the sensors. At the same time, in the wireless terminal, the matching parameters are preset, and the corresponding matching parameters are selected according to the detection signal of the sensor, and the impedance of the matching network circuit is adjusted by using the matching parameters, so that the impedance of the matching network circuit matches the impedance of the antenna, so that the antenna Work in optimal...
