The signal processing method of the electronic device and the electronic device provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
In some embodiments of the present application, a signal processing method of an electronic device is provided, and fig. 1 shows a flowchart of the signal processing method of the electronic device provided according to an embodiment of the present application, as shown in fig. 1, the method includes:
step 102, determining the signal characteristics of a second signal under the condition that the first signal is received and the second signal is sent to an external component;
in step 102, the first signal is a radio frequency signal, and the second signal is used for controlling the peripheral component to work;

In the embodiment of the application, the peripheral components of the electronic equipment comprise components controlled by digital signals such as a screen, a processor and a baseband, and the first signal is a radio frequency signal received by a radio frequency antenna of the electronic equipment and comprises a 4G signal, a 5G signal, a Wi-Fi signal and the like.
The signal transmission can be carried out between the electronic equipment and the peripheral component, wherein the signal transmission can be unidirectional signal transmission, namely, the signal transmission only comprises the condition that the electronic equipment sends signals to the peripheral component, for example, when the peripheral equipment is an earphone, the electronic equipment unidirectionally transmits audio signals to the earphone; or simply includes the peripheral component sending a signal to the electronic device, such as the peripheral device being a sensor or the like, which unidirectionally transmits a detection signal to the electronic device.
In other embodiments, the signal transmission may be bidirectional, that is, the electronic device sends a signal to the external component while the external component sends a signal to the electronic device, for example, the external device is an external touch screen, and the external touch screen sends a touch signal to the electronic device while the electronic device sends a video signal to the external touch screen.
If the electronic device receives the first signal and simultaneously drives the peripheral component, the processor of the electronic device needs to send an enabling control signal to the peripheral component, so as to control the peripheral component to execute a corresponding job, such as controlling the display screen to display specific content. At this time, the second signal, which is a digital signal, may generate signal interference with the first signal, which is an analog signal.
When the peripheral component is called, the processor of the electronic device sends an enabling control signal, namely a second signal, to the peripheral device, and the processor processes and calculates the signal characteristics of the second signal while sending the second signal, and generates an inverted signal, namely a third signal, of the second signal in the frequency domain according to the processed signal characteristics of the second signal.
Since the third signal is an inverted signal of the second signal in the frequency domain, the third signal corresponds to an inverted signal of an interference signal formed by the second signal (digital signal) in the first signal (analog signal), and therefore, by processing the first signal by the third signal, the third signal is superimposed on the first signal, and the interference formed by the second signal in the first signal can be offset to some extent, thereby improving the signal quality of the first signal.
According to the embodiment of the application, the second signal of the digital signal is converted from the time domain to the frequency domain, so that the inverted signal of the second signal in the frequency domain is finally obtained, and the inverted signal can offset the interference signal generated by the superposition of the second signal in the first signal to a certain extent, thereby reducing the signal interference of the digital signal system to the analog signal system. The method is realized through a logic algorithm, so that shielding auxiliary materials are not required to be arranged in electronic equipment such as mobile phones and the like aiming at a digital signal system, the manufacturing cost of the electronic equipment is effectively reduced, meanwhile, the method does not use the shielding auxiliary materials, the signal anti-interference effect cannot be weakened along with time, the interference of the digital signal system to an analog signal system can be guaranteed to be reduced for a long time, and the radio frequency signal quality of the electronic equipment is improved.
In some embodiments of the application, determining the signal characteristics of the second signal comprises: and carrying out Fourier transformation on the second signal to obtain signal characteristics, wherein the signal characteristics comprise frequency points of the third signal and signal intensities corresponding to the frequency points.
In an embodiment of the application, the signal characteristics of the second signal are determined by fourier transforming the second signal. Specifically, for a typical periodic digital signal, the period directly affects the frequency of the frequency spectrum component after fourier transformation, for example, when the period of the signal is T, ω and its multiplied interference frequency point are generated on the frequency spectrum after fourier transformation.
Therefore, when the second signal is processed, the period T of the second signal is converted into the frequency domain ω by fourier transformation, and the correspondence between each frequency point and the signal intensity in the frequency domain ω is obtained according to the signal intensity of the second signal, thereby obtaining the signal characteristics of the second signal.
The application obtains the inverse signal of the second signal in the frequency domain, namely the third signal by the Fourier transformation mode, and carries out signal processing on the radio frequency signal received by the receiver, namely the first signal by the third signal, thereby reducing the signal interference caused by the digital signal system to the analog signal system and improving the signal quality of the electronic equipment.
In some embodiments of the application, the electronic device includes a modem that generates a third signal based on the signal characteristics, including: transmitting the signal characteristics to a modem; the control modem generates a third signal.
In the embodiment of the application, the electronic equipment is provided with the modem, and in particular, the modem is connected with the processor of the electronic equipment and the radio frequency antenna, the radio frequency antenna receives radio frequency radiation, so that a corresponding video analog signal is generated, and the modem can demodulate the radio frequency analog signal received by the radio frequency antenna into a digital signal and send the digital signal to the processor.
Meanwhile, after the processor generates the signal characteristics of the second signal, the signal characteristics of the second signal are sent to the modem, and after the modem receives the signal characteristics, the second signal of the digital signal is inverted according to different frequency points and corresponding signal intensity, so that a corresponding third signal, namely an inverted signal of the second signal in a frequency domain, can be generated by modulation.
The third signal is used for processing the received radio frequency signal (first signal), so that the interference of the digital signal system to the analog signal system can be reduced, and the signal quality of the electronic equipment can be improved.
In some embodiments of the application, the electronic device further comprises a receiver for receiving the first signal, the receiver comprising a mixer; processing the first signal according to the third signal to obtain a processed target signal, including: transmitting the third signal to the receiver; the mixer is controlled to superimpose the third signal on the first signal to obtain a target signal.
In the embodiment of the application, the electronic device further comprises a receiver, and the receiver is connected with the radio frequency antenna of the electronic device, so that a corresponding radio frequency signal, namely the first signal, is obtained according to the signal fed in from the radio frequency world. The receiver comprises a mixer which can superimpose the third signal generated by the modem on the first signal, and can effectively cancel the interference signal of the second signal mixed in the first signal because the third signal is an inverse signal of the second signal in the frequency domain, thereby improving the signal quality of the target signal.
Specifically, fig. 2 shows a schematic structural diagram of an electronic device according to an embodiment of the present application, and as shown in fig. 2, the electronic device includes an analog signal system such as a processor 202, a modem 204, a receiver 206, and a radio frequency antenna 208, and further includes a digital signal system of a peripheral component 210.
The rf antenna 208 receives an external signal and sends the external signal to the receiver 206 through the path 5, the receiver 206 sends the received rf signal to the modem 204 through the path 6, and the modem 204 demodulates the received rf signal to obtain a corresponding digital signal and sends the digital signal to the processor through the path 7, thereby completing signal reception.
In operation, the peripheral component 210 may transmit its operating signal to the rf antenna 208 via the coupling path 4, resulting in interference with the rf signal received by the rf antenna 208. Thus, while processor 202 is sending an enable control signal to an external component via path 2, the processor is sending the signal characteristics of the enable control signal to modem 204 via path 1.
The modem 204 generates an inverted signal of the enable control signal in the frequency domain based on the signal characteristics and transmits it to the receiver 206 via path 3. The receiver 206 adds the inverse signal to the received rf signal through the mixer provided therein, so as to obtain a corrected rf signal, that is, the target signal, and the modem 204 demodulates the corrected target signal, so that the signal quality can be improved.
In some embodiments of the application, the method further comprises, prior to sending the second signal to the peripheral component: acquiring first signal quality of a fourth signal received by a receiver, wherein the fourth signal is a radio frequency signal; after obtaining the processed target signal, the method further comprises: acquiring a second signal quality of the target signal; and adjusting the signal strength of the third signal according to the first signal quality and the second signal quality.
In the embodiment of the application, when the processor does not send the second signal to the external component, that is, when the digital signal system does not work, the system does not have the digital signal, and the fourth signal received by the radio frequency antenna and the receiver is the radio frequency signal without the digital signal interference. At this time, a first signal quality of the fourth signal is determined, the first signal quality being indicative of a radio frequency signal quality of the electronic device in the absence of digital signal interference.
Under the condition that the peripheral component works, signal processing is carried out on the first signal received by the current receiver by generating a third signal corresponding to an enabling control signal of the peripheral component, namely an inverted signal of the second signal in a frequency domain, the third signal is overlapped with the first signal to obtain a processed target signal, at the moment, the second signal quality of the target signal is obtained, and the second signal quality can indicate the corrected radio frequency signal, namely the radio frequency signal quality of the target signal.
At this time, the second signal quality and the first signal quality are compared, and the effect of the third signal on the first signal correction can be reflected by the difference between the second signal quality and the first signal quality. If the difference between the two signals is smaller, the correction effect of the third signal on the first signal is obvious, and the signal quality of the target signal is good. If the difference between the two signals is larger, the fact that the correction effect of the third signal on the first signal is insufficient is indicated, and at the moment, the signal intensity of the third signal is adjusted, so that the signal correction effect is optimized, and the signal quality of the electronic equipment is improved.
In some embodiments of the application, the first signal quality and the second signal quality each comprise: one or more of received signal strength, bit error rate, and error vector magnitude; adjusting the signal strength of the third signal according to the first signal quality and the second signal quality, comprising: and adjusting the signal strength of the third signal based on the difference value when the second signal quality is smaller than the first signal quality and the difference value between the second signal quality and the first signal quality is larger than the preset difference value.
In an embodiment of the present application, in order to enable the first signal quality and the second signal quality to be quantized, the embodiment of the present application performs quantization definition on the signal quality by using the received signal strength (Received Signal Strength Indicator, RSSI), the bit error rate and the error vector magnitude (Error Vector Magnitude, EVM).
If the second signal quality of the target signal obtained after the third signal is superimposed is still smaller than the first signal quality of the fourth signal when the digital signal system does not work and the signal quality difference between the second signal quality and the first signal quality is larger than the preset difference, the fact that the correction strength of the radio frequency signal, namely the first signal, is insufficient is indicated, at the moment, the signal strength of the third signal is corrected according to the difference between the second signal strength and the first signal strength, so that the correction amplitude of the third signal to the first signal is adjusted, and the signal quality of the target signal is improved.
The application adjusts the signal intensity of the inverse signal of the digital signal in the frequency domain based on the quantifiable signal quality, thereby adjusting the correction strength of the radio frequency signal so that the signal quality of the corrected radio frequency signal meets the communication requirement.
