Detailed Description
Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The signal processing circuit, the method, the device and the electronic equipment 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.
Signal interference refers to the phenomenon that a signal which is not specified according to frequency allocation occupies the frequency of a legal signal, so that the legal signal cannot work normally. For example, the existing dedicated radio system occupies existing frequency resources, the network configuration of different operators is improper, the cells overlap, the environment, electromagnetic compatibility and intentional interference are all the reasons for the radio frequency interference generated by the mobile communication network. The radio frequency resources occupied by the existing mobile communication system are below 6G, and the characteristic of the frequency band is the relation between interference and interfered, so that the mobile communication network inevitably has the problem of radio frequency interference.
As shown in fig. 1, the signal processing circuit in the electronic device of the prior art includes: a signal processing sub-circuit 101 of the LTE/NR band and a signal processing sub-circuit 102 of the WiFi band. The signal processing sub-circuit 101 of the LTE/NR band may include a main radio frequency transceiver, a radio frequency signal module, a double Pole double Throw switch (DPDT), a low noise amplifier (Lower Noise Amplifier, LNA), and an antenna ANT. The rf signal module may include a Power Amplifier (PA), a Single-Pole Dual-through (SPDT), and a Band Pass Filter (BPF). The signal processing sub-circuit 102 of the WiFi frequency band may include a WiFi signal transceiver, a WiFi signal module, a band pass filter BPF, and an antenna ANT. The WiFi signal module may include two single pole double throw switches SPDT, a power amplifier PA, and a low noise amplifier LNA.
The signal processing sub-circuit 101 of the LTE/NR band and the signal processing sub-circuit 102 of the WiFi band are two circuits that operate independently. When a user switches the data connection mode to a mobile data connection (for example, 4G), the electronic device may implement data transmission with the network device based on the signal processing sub-circuit 101 of the LTE/NR frequency band; when the user switches the data connection mode to the wireless network connection, the electronic device may implement data transmission with the network device based on the signal processing sub-circuit 102 in the WiFi frequency band. However, in any data transmission mode, the signal receiving time slot may be affected by the downlink interference signal, that is, when the electronic device receives the signal sent by the network device, the electronic device also receives the downlink interference signal, thereby affecting the signal demodulation quality and reducing the sensitivity and the communication experience of the user.
Based on the above-described problems, the present embodiment provides a signal processing circuit, as shown in fig. 2, including: a first signal transceiver 210, a second signal transceiver 220, a first signal module 230, a second signal module 240, and a single pole, triple throw switch 250.
The first signal module 230 is connected to an input end of the single-pole three-throw switch 250, a first output end of the single-pole three-throw switch 250 is connected to a signal transmitting end TX1 of the first signal transceiver 210, a second output end of the single-pole three-throw switch 250 is connected to an Idle end Idle of the first signal transceiver 210, a third output end of the single-pole three-throw switch 250 is connected to a Noise detecting end noise_rx_detect of the second signal transceiver 220, and a signal transmitting end TX0 and a signal receiving end RX0 of the second signal transceiver 220 are respectively connected to the second signal module 240.
It should be noted that, with continued reference to fig. 2, in order to ensure the normal operation of the signal transmission function of the signal processing circuit, the signal processing circuit may further include a band-pass filter BPF, a double pole double throw switch DPDT, a low noise amplifier LNA, and an antenna ANT. Wherein, one end of the band-pass filter BPF is connected with the first signal module 230, the other end is connected with the antenna, one end of the double pole double throw switch DPDT is connected with the second signal module 240, the other end is connected with the antenna, the input end of the low noise amplifier LNA is connected with the second signal module 240, and the output end is connected with the signal receiving end RX0 of the second signal transceiver 220.
Optionally, in the case that the input end and the first output end of the single pole three throw switch 250 are in a conductive state, the first signal transceiver 210 performs signal transmission with the network device through the first signal module 230 and the antenna connected to the first signal module 230; meanwhile, the second signal transceiver 220 may also realize signal transmission with the network device through the second signal module 240 and the antenna connected with the second signal module 240; the signal transmission between the first signal transceiver 210 and the second signal transceiver 220 and the network device is performed independently. In the case where the input terminal and the second output terminal of the single pole triple throw switch 250 are in a conductive state, the first signal transceiver 210 and the first signal module 230 are in a null state, and no signal transmission is performed between the first signal transceiver and the network device in the null state. At this time, the second signal transceiver 220 may implement signal transmission with the network device through the second signal module 240 and the antenna connected to the second signal module 240. The signal transmission between the first signal transceiver 210 and the second signal transceiver 220 and the network device is in a relatively independent state, and the conduction relationship between the input terminal and the different output terminals of the single pole three throw switch 250 only affects whether the signal transmission between the first signal transceiver 210 and the network device is performed, and does not affect the signal transmission between the second signal transceiver and the network device. In the case that the input terminal and the third output terminal of the single pole triple throw switch 250 are in the on state, the second signal transceiver 210 may detect an interference signal of a signal receiving slot through the first signal module 230 and an antenna connected to the first signal module 230, the second signal transceiver 220 may receive a total signal from the network device through the second signal module 240 and an antenna connected to the second signal module 240, and determine the interference signal detected by the first signal module 230 as an interference signal received by the second signal transceiver, process the interference signal received through the first signal module 230 in the second signal transceiver 220, and determine a difference between the total signal and the interference signal received by the second signal transceiver as a useful signal received by the second signal transceiver.
Alternatively, the first signal transceiver 210 may correspond to a first data connection mode, and the second signal transceiver 220 may correspond to a second data connection mode. In the case where the signal processing circuit is in the first data connection mode, the input terminal and the first output terminal of the single pole three throw switch 250 are in a conductive state, and the signal processing circuit may be simultaneously in the second data connection mode. When the signal processing circuit is in the second data connection mode and the demodulation rate of the received signal by the second signal transceiver 220 is greater than or equal to the first threshold, the input terminal and the second output terminal of the single pole three throw switch 250 are in a conductive state, and at this time, the first data connection is in a disconnection state. When the signal processing circuit is in the second data connection mode and the demodulation rate of the received signal by the second signal transceiver 220 is less than the first threshold, the input terminal and the third output terminal of the single pole three throw switch 250 are in the on state, and at this time, the first data connection is in the off state.
Illustratively, the first data connection is a wireless network connection, and the second data connection is a mobile data connection. In one case, when a Wi-Fi signal exists in the surrounding environment of the electronic device and a user needs to connect with the Wi-Fi route, the electronic device can control the single-pole three-throw switch 250 to conduct a path between the input end and the first output end, so that the electronic device can realize a signal receiving and transmitting function with the network device based on the Wi-Fi signal; at this time, the electronic device is not affected by the signal transmitting and receiving function between the mobile data signal and the network device, and the mobile data signal transmission between the electronic device and the network device is normally performed. In another case, when the electronic device is not connected to the Wi-Fi route and the demodulation rate of the received signal by the electronic device is greater than or equal to the first threshold, that is, the electronic device uses mobile data connection, and the network signal is good, the electronic device may control the single pole three throw switch 250 to switch on the path between the input end and the second output end, so that the electronic device may implement a signal transceiving function with the network device based on the mobile data signal. In another case, when the electronic device is not connected to the Wi-Fi route and the demodulation rate of the electronic device to the received signal is smaller than the first threshold, that is, the electronic device uses mobile data connection, but when the network signal is poor, the signal interference intensity at this time can be considered to be high, and in order to ensure the communication quality, interference filtering needs to be performed on the received downlink signal. Specifically, the electronic device may control the single pole three throw switch 250 to switch on the path between the input terminal and the third output terminal, so that the electronic device may detect the interference signal of the signal receiving slot based on the first signal module 230, receive the total signal from the network device based on the second signal transceiver 220, determine the interference signal detected by the first signal module 230 as the interference signal received by the second signal transceiver 220, and determine the difference between the total signal and the interference signal received by the second signal transceiver 220 as the useful signal received by the second signal transceiver 220. Thereby filtering out the environmental interference and obtaining a relatively pure useful signal.
In this embodiment of the present application, when the input end and the third output end of the single-pole triple-throw switch are in a conducting state, the first signal module may detect an interference signal of a signal receiving slot, the second signal transceiver may receive a total signal from the network device, and since the interference signal detected by the first signal module may be determined as an interference signal received by the second signal transceiver, the second signal transceiver may determine a useful signal according to the received total signal and the interference signal. Therefore, the interference signals of the signal receiving time slots can be screened out, so that the signal to noise ratio is improved, the signal transmission rate is improved, and the communication experience of a user is further improved.
As shown in fig. 3, the embodiment of the present application further provides a signal processing method, which is applied to a signal processing apparatus including the signal processing circuit shown in fig. 2, and the method may include steps 301 and 302:
step 301, acquiring an interference signal detected by the first signal module in a signal receiving time slot and a total signal received by the second signal transceiver from the network device when the signal processing device and the network device are in a second data connection mode and the demodulation rate of the received signal by the second signal transceiver is smaller than a first threshold value.
Optionally, when the signal processing device is in a communication connection state with the network device, the signal processing device may detect whether the first signal transceiver is in a working state, that is, determine whether the signal processing device is based on a communication connection established by the first data connection mode with the network device, if so, the signal processing device may continuously detect whether the first signal transceiver is in a working state, if not, it indicates that the signal processing device is based on a communication connection established by the second data connection mode with the network device, and the signal processing device may further determine a demodulation rate of the received signal by the second signal transceiver.
Optionally, the signal processing device may first establish a communication connection with the network device based on the second data connection manner; then, transmitting first indication information to the network device through the second signal transceiver, wherein the first indication information can be used for indicating the network device to transmit a test signal; the signal processing device can then receive the test signal sent by the network device through the second signal transceiver, and determine the demodulation rate of the received signal by the second signal transceiver according to the test signal.
Specifically, after the signal processing device establishes a communication connection with the network device based on the second data connection manner, the signal processing device may send an indication information to the network device to instruct the network device to send a known signal to the signal processing device, and after the signal processing device receives the test signal, since the test signal may include the known signal and the interference signal, the signal processing device may determine a demodulation rate of the received signal by the second signal transceiver according to the known signal and the test signal.
After determining the demodulation rate of the second signal transceiver to the received signal, the signal processing device may compare the demodulation rate with a preset first threshold, and if the demodulation rate is smaller than the first threshold, the signal processing device may obtain the interference signal detected by the first signal module in the signal receiving time slot and the total signal from the network device received by the second signal transceiver.
Based on the above scheme, since the demodulation rate of the second signal transceiver to the received signal can be determined by the test signal sent by the network device, whether more interference exists in the current network state can be determined according to the demodulation rate, so as to provide a reference for whether to perform downlink signal interference processing.
Optionally, the signal processing device acquires an interference signal detected by the first signal module in a signal receiving time slot, which specifically may include: the signal processing device carries out phase shifting processing in a first direction on a first signal received by the first signal module in a signal receiving time slot to obtain a second signal; filtering useful signals in the second signals to obtain third signals; then, carrying out phase shifting processing on the third signal in a second direction to obtain an interference signal detected by the first signal module in a signal receiving time slot; wherein the first direction is opposite to the second direction.
Specifically, the signal processing device may perform phase shift processing in a first direction on a first signal received by the first signal module in a signal receiving slot through the phase shifter, so as to achieve the purpose that the interference signal is orthogonal to the useful signal, and then may filter the useful signal from the network device, and perform phase shift processing in a second direction again, so as to obtain the interference signal.
Based on the scheme, the useful signals in the second signals can be filtered through phase shifting, so that purer interference signals can be obtained, and the accuracy of downlink signal interference processing is improved.
Step 302, determining an interference signal detected by the first signal module as an interference signal received by the second signal transceiver, and determining a difference between the total signal and the interference signal received by the second signal transceiver as a useful signal received by the second signal transceiver.
Because the antenna corresponding to the first signal module is very close to the antenna corresponding to the second signal transceiver, the signal interference suffered by the first signal module can be considered to be equivalent, that is, the signal processing device can determine the interference signal detected by the first signal module as the interference signal suffered by the second signal transceiver. After determining the interference signal received by the second signal transceiver, the signal processing means may determine the difference between the total signal and the interference signal received by the second signal transceiver as the useful signal received by the second signal transceiver.
It should be noted that, in the embodiment of the present application, the first data connection manner may be a wireless network connection, and the second data connection manner may be a mobile data connection.
It should be noted that, in the embodiment of the present application, the signal processing process of the downlink signal is described by taking the noise detection unit of the first signal module as the second signal transceiver as an example, and in practical application, the second signal module may also be used as the noise detection unit of the first signal transceiver, so that the detailed description of this embodiment of the present application will not be repeated.
Optionally, in a case that the signal processing apparatus is in the second data connection manner with the network device and the demodulation rate of the received signal by the second signal transceiver is greater than or equal to the first threshold, the signal processing apparatus may implement signal transmission with the network device based on the second signal transceiver.
Alternatively, the signal processing means may implement signal transmission with the network device based on the first signal transceiver in case the signal processing means is in the first data connection with the network device.
That is, the signal processing method provided by the embodiment of the present application may filter the downlink interference received by the second signal transceiver without affecting the original functions performed by the first signal transceiver and the second signal transceiver, so as to improve the communication experience of the user.
The following describes and explains the scheme flow provided in the embodiment of the present application in detail by way of an example.
As shown in fig. 4, in an exemplary case where the signal processing device and the network device are in a communication connection state, the signal processing device may first determine whether the current network connection mode is a wireless network connection, if yes, continuously monitor and determine the current network connection mode, that is, determine whether the network connection mode is still a wireless network connection; if not, the current network connection mode is mobile data connection, and because the mobile data connection corresponds to the second signal transceiver, whether the demodulation rate of the received signal by the second signal transceiver is smaller than a first threshold value or not needs to be further judged, namely, the current network communication quality is evaluated, if the demodulation rate is smaller than the first threshold value, an interference signal is detected through the first signal module, a total signal is detected through the second signal transceiver, and a useful signal is determined according to the interference signal and the total signal. If the demodulation rate is not less than the first threshold, the process ends.
In this embodiment of the present application, the first signal module may detect an interference signal of a signal receiving slot, and the second signal transceiver may receive a total signal from the network device, and since the interference signal detected by the first signal module may be determined as the interference signal received by the second signal transceiver, the second signal transceiver may determine a useful signal according to the received total signal and the interference signal. Therefore, the interference signals of the signal receiving time slots can be screened out, so that the signal to noise ratio is improved, the signal transmission rate is improved, and the communication experience of a user is further improved.
In the signal processing method provided in the embodiment of the present application, the execution body may be a signal processing apparatus. In the embodiment of the present application, a signal processing device is described by taking a signal processing method performed by the signal processing device as an example.
As shown in fig. 5, an embodiment of the present application further provides a signal processing apparatus 500, including: an acquisition module 501 and a processing module 502. The obtaining module 501 is configured to obtain, when the signal processing apparatus is in a second data connection manner with the network device and the demodulation rate of the received signal by the second signal transceiver is less than a first threshold, an interference signal detected by the first signal module in a signal receiving time slot and a total signal received by the second signal transceiver from the network device.
