All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
In order to optimize the performance of an antenna and improve user experience, embodiments of the present invention provide an antenna frequency modulation system, a frequency modulation method, a device, and a medium.
Example 1:
fig. 1 is a schematic structural diagram of an antenna frequency modulation system according to an embodiment of the present invention, where the system includes: a signal detection module 101, a radio frequency modulator 102 and an antenna tuning module 103, wherein the radio frequency modulator 102 is respectively connected to the signal detection module 101 and the antenna tuning module 103:
the signal detection module 101 is configured to send the current working frequency band of the antenna to the radio frequency modulator 102 when it is determined that the signal strength of the antenna does not meet the requirement of the current scene;
the radio frequency modulator 102 is configured to sequentially adjust parameters of a variable capacitance switch in the antenna tuning module 103 according to at least two tuning values corresponding to the working frequency band;
the signal detection module 101 is further configured to determine a target tuning value corresponding to the maximum signal strength, and send the target tuning value to the radio frequency modulator 102;

The antenna frequency modulation system provided by the embodiment of the invention comprises: the antenna frequency modulation system is applied to electronic equipment, and the electronic equipment can be mobile phones, tablet computers and other electronic equipment which can be used for communication.
In order to optimize the performance of the antenna and enable the performance of the antenna to meet requirements of different scenes, the signal detection module in the embodiment of the invention detects the signal intensity of the antenna in real time, when the signal intensity of the antenna is determined not to meet the requirements of the current scene, the tuning value of the antenna is determined to be required to be adjusted, and in order to facilitate the adjustment of the tuning value, the signal detection module sends the current working frequency band of the antenna to the radio frequency modulator.
And the radio frequency modulator is connected with the antenna tuning module, and after receiving the working frequency band sent by the signal detection module, the radio frequency modulator adjusts the parameters of the variable capacitance switch in the antenna tuning module according to the tuning value so as to enable the signal intensity emitted by the antenna to meet the requirements of the current scene. Specifically, when adjusting the parameters, the radio frequency modulator stores at least two tuning values, generally a plurality of tuning values, for each operating frequency band of each antenna, for example, 20 tuning values may be stored for one operating frequency band, so that after the radio frequency modulator receives the operating frequency band, the parameters of the variable capacitance switch in the antenna tuning module are adjusted according to each stored tuning value corresponding to the operating frequency band and the corresponding relationship between the tuning value and the parameter of the variable capacitance switch, and the signal intensity of the antenna will be changed once per adjustment.
In order to determine which adjusted parameters of the variable capacitance switch can enable the transmitted signal strength to meet the requirements of the current scene, the signal detection module detects the signal strength transmitted by the antenna, determines the maximum value of the signal strength, determines a tuning value corresponding to the maximum value of the signal strength, takes the tuning value corresponding to the maximum value of the signal strength as a target tuning value, and sends the target tuning value to the radio frequency modulator.
Specifically, when the signal detection module determines the target tuning value, the signal detection module may also store a corresponding relationship between an operating frequency band of the antenna and the tuning value, in order to enable the signal detection module to determine the signal strength after adjusting the parameter of the variable capacitance switch each time, when the radio frequency modulator adjusts the parameter of the variable capacitance switch according to the tuning value, the radio frequency modulator needs to perform the adjustment according to a set time interval, that is, wait for a set time period after adjusting the parameter of the variable capacitance switch, the time period is generally short, for example, several milliseconds, but the time interval enables the signal detection module to determine the signal strength, the corresponding relationships between the operating frequency band and the tuning value stored by the signal detection module and the radio frequency modulator are consistent, and the sequence of the tuning values is also consistent, when the radio frequency modulator adjusts, the sequence of the tuning values is adjusted, so that the signal detection module can record the adjusted signal strength for each tuning value, thereby determining the signal strength maximum.
After the signal detection module determines the maximum value of the signal strength, the tuning value when the maximum value of the signal strength is identified is determined, the tuning value is determined as a target tuning value, and the target tuning value is sent to the radio frequency modulator, so that the radio frequency modulator can know which tuning value has the maximum signal strength.
After the radio frequency modulator receives the target tuning value, according to the corresponding relation between the tuning value and the parameter of the variable capacitance switch, the parameter of the variable capacitance switch corresponding to the target tuning value is determined, and the parameter of the variable capacitance switch in the antenna tuning module is adjusted to enable the signal intensity of the antenna to be the maximum value.
According to the embodiment of the invention, when the signal intensity does not meet the requirement of the current scene, the signal detection module determines the corresponding target tuning value when the signal intensity is maximum, and the radio frequency modulator adjusts the parameters of the variable capacitance switch in the antenna tuning module according to the target tuning value, so that the optimization of the antenna performance is finally realized, the performance of the antenna can be adapted to the current scene, and the user experience is improved.

in order to optimize the performance of the antenna and improve the user experience, on the basis of the above embodiment, in the embodiment of the present invention, the system further includes: a system baseband circuit 104, wherein the system baseband circuit 104 is connected to the signal detection module 101:
the signal detection module 101 is specifically configured to receive a first baseband signal generated by a system baseband circuit 104, determine a first signal strength of an antenna according to the first baseband signal, and determine that the first signal strength does not meet a requirement of a current scene if the first signal strength is smaller than a set strength threshold.
The antenna frequency modulation system also comprises a system baseband circuit, and the system baseband circuit is connected with the signal detection module, so that the signal detection module can determine the signal intensity.
In order to enable the signal detection module to obtain the signal strength of the antenna, so as to determine whether the signal strength of the antenna in the current working frequency band meets the requirements of the current scene, in the embodiment of the invention, the signal detection module is connected with the system baseband circuit, obtains a first baseband signal generated by the system baseband circuit, and determines the first signal strength according to the first baseband signal. The process of determining the signal strength based on the baseband signal is the prior art, and is not described in detail in the embodiment of the present invention.
In order to determine whether the signal strength meets the requirement of the current scene, in the embodiment of the present invention, a strength threshold is preset, after the first signal strength is determined, the first signal strength is compared with the preset strength threshold, if the first signal strength is smaller than the strength threshold, it is determined that the first signal strength does not meet the requirement of the current scene, otherwise, it is determined that the first signal strength meets the requirement of the current scene. The magnitude of the intensity threshold may be set according to the requirement of the call quality, and the magnitude of the value is not limited in the embodiment of the present invention.
Example 3:
in order to optimize the performance of the antenna and improve the user experience, on the basis of the foregoing embodiments, in the embodiment of the present invention, the system further includes: a system baseband circuit 104, wherein the system baseband circuit 104 is connected to the signal detection module 101:
the radio frequency modulator 102 is further configured to send a tuning value corresponding to each parameter adjustment to the signal detection module 101;
the signal detection module 101 is specifically configured to obtain, according to the obtained tuning value, a second baseband signal generated by the system baseband circuit 104 when the tuning value is obtained; determining a second signal strength from the second baseband signal.
In order to obtain a tuning value corresponding to each time of parameter adjustment of the variable capacitance switch and a signal strength after each time of parameter adjustment of the variable capacitance switch, the radio frequency modulator is connected with the signal detection module, and sends the corresponding tuning value to the signal detection module after the radio frequency modulator adjusts the parameter of the variable capacitance switch. Because the system baseband circuit is connected with the signal detection module, the tuning value will be changed after the parameter of the variable capacitance switch is adjusted, the second baseband signal generated by the system baseband circuit will also be changed, the second baseband signal generated by the system baseband circuit is obtained after the signal detection module obtains the tuning value sent by the radio frequency modulator, and the signal detection module determines the second signal intensity according to the second baseband signal.
Or, before the radio frequency modulator adjusts the parameter of the variable capacitance switch, the corresponding tuning value is sent to the signal detection module, the parameter of the variable capacitance switch in the antenna tuning module is adjusted, and after the signal detection module acquires the tuning value sent by the radio frequency modulator, the second baseband signal generated by the system baseband circuit is acquired, and the second signal strength is determined according to the second baseband signal. And finally, the signal detection module obtains a tuning value corresponding to the parameter adjustment of the variable capacitance switch and a corresponding second signal strength.
In order to optimize the performance of the antenna and improve the user experience, on the basis of the foregoing embodiments, in an embodiment of the present invention, the signal detection module is specifically configured to determine, according to each obtained tuning value and each determined second signal strength, a tuning value corresponding to a maximum value of the second signal strength, and send the tuning value as a target tuning value to the radio frequency modulator.
When the radio frequency modulator is adjusted, parameters of the variable capacitance switch in the antenna tuning module are sequentially adjusted according to the sequence of tuning values, and the signal detection module can acquire each tuning value and the signal intensity corresponding to each tuning value.
In order to determine the maximum value of the second signal strength, so as to optimize the antenna performance, the signal detection module may identify the maximum value of the second signal strength according to the determined magnitude of the second signal strength, use a tuning value corresponding to the maximum value as a target tuning value, and send the target tuning value to the radio frequency modulator. The radio frequency modulator locks the target tuning value, namely, the parameters of the variable capacitance switch in the antenna tuning module are determined according to the corresponding relation between the tuning value and the variable capacitance switch when the target tuning value is obtained, and the parameters of the variable capacitance switch are controlled according to the parameters for adjustment, so that the optimization of the antenna performance is finally realized.
