To facilitate an understanding of the present application, relevant technical knowledge related to embodiments of the present application will be first introduced herein.
In the aspect of adjacent channel interference suppression, an analog filter and an ACI filter can be adopted to filter the adjacent channel interference. However, because the filter has a transition band, when the adjacent channel interference is strong, the adjacent channel interference can not be effectively suppressed; meanwhile, if the transition band falls within the frequency band of the useful signal or the target signal, the loss of the useful signal or the target signal is caused. To solve this problem, the filter order is usually increased, but increasing the filter order increases the group delay on the one hand and increases the implementation complexity on the other hand.
In order to solve the above problem, in the embodiments of the present application, a zero intermediate frequency receiver or a near-zero intermediate frequency receiver is adaptively selected according to the strength of adjacent channel interference to receive a target signal and a frequency point at which the zero intermediate frequency receiver receives the target signal, so that the adjacent channel interference suppression capability is enhanced.
Fig. 2 is a schematic structural diagram of a terminal according to an embodiment of the present application, where the terminal 110 includes an adaptive receiver 111 and a neighbor interference selector 112. Wherein the adaptive receiver 111 comprises a zero intermediate frequency receiver and a near-zero intermediate frequency receiver, and the adjacent channel interference selector 112 may be a processor, a modem, or a dedicated device for performing the corresponding adjacent channel interference selection action. The terminal may receive the narrowband signal by using the adaptive receiver 111, and instruct the switching of the adaptive receiver, that is, the switching between the zero intermediate frequency receiver and the near-zero intermediate frequency receiver, and the switching of the receiving position (frequency point) of the near-zero intermediate frequency receiver, through the adjacent channel interference selector 112, so that most of the adjacent channel interference is suppressed in the receiving stage. In addition, the aim of further suppressing adjacent channel interference can be achieved by matching with an ACI filter.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for suppressing adjacent channel interference according to an embodiment of the present application, where the method for suppressing adjacent channel interference is applied to a terminal and includes the following operations.
Step 301, determining the adjacent channel interference strength in the target signal.
Step 302, a target intermediate frequency receiver is enabled according to the adjacent channel interference strength.
Step 303, if the target if receiver is a zero if receiver, receiving the target signal through the zero if receiver.
Step 304, if the target intermediate frequency receiver is a near-zero intermediate frequency receiver, determining a frequency point which needs to be enabled by the near-zero intermediate frequency receiver, and receiving the target signal at the frequency point through the near-zero intermediate frequency receiver.
The target intermediate frequency receiver may be an intermediate frequency receiver whose adjacent channel interference strength suppression strength is greater than a preset strength. That is, when the adjacent channel interference strength in the target signal is greater, that is, the adjacent channel interference strength in the target signal is greater than the preset strength, the target if receiver needs to be enabled, otherwise, a general if receiver can be used to receive the target signal.
It can be seen that, in the adjacent channel interference suppression method provided in the embodiment of the present application, the terminal determines the adjacent channel interference strength in the target signal first; then starting a target intermediate frequency receiver according to the adjacent channel interference strength; if the target intermediate frequency receiver is a zero intermediate frequency receiver, the terminal receives the target signal through the zero intermediate frequency receiver; if the target intermediate frequency receiver is a near-zero intermediate frequency receiver, the terminal determines a frequency point which needs to be started by the near-zero intermediate frequency receiver, and receives the target signal at the frequency point through the near-zero intermediate frequency receiver. Therefore, by implementing the adjacent channel interference suppression method provided by the embodiment of the application, the terminal can adaptively select the frequency point at which the zero intermediate frequency receiver or the near-zero intermediate frequency receiver receives the target signal and the frequency point at which the zero intermediate frequency receiver receives the target signal according to the adjacent channel interference strength, thereby being beneficial to enhancing the suppression capability of the adjacent channel interference.
In one possible example, the determining the strength of the adjacent channel interference in the target signal includes: determining a signal strength RSSI of the target signal; and determining the adjacent channel interference relative strength in the target signal according to the signal strength RSSI of the target signal.
The RSSI for determining the signal strength of the target signal may be obtained by an indirect method or by direct measurement. For example, the signal strength RSSI of the target signal may be estimated by the signal strength RSSI of the wideband, the signal strength RSSI of the left adjacent channel and the signal strength RSSI of the right adjacent channel of the target signal, or the signal strength RSSI of the target signal may be directly measured by a filter.
Therefore, in this example, the terminal may determine the relatively strong strength of the adjacent channel interference in the target signal by determining the signal strength RSSI of the target signal, and use the relatively strong strength of the adjacent channel interference as the adjacent channel interference strength in the target signal, which is beneficial to accurately obtain the adjacent channel interference strength in the target signal.
In one possible example, the determining the signal strength RSSI of the target signal comprises: obtaining a signal strength RSSI of a broadband through a broadband filter, wherein the broadband comprises a target channel for transmitting the target signal; obtaining the signal strength RSSI of the left adjacent channel and the signal strength RSSI of the right adjacent channel of the target channel through a sideband filter; and determining the signal strength RSSI of the target signal according to the signal strength RSSI of the broadband, the signal strength RSSI of the left adjacent channel and the signal strength RSSI of the right adjacent channel.
For example, referring to fig. 4 together, fig. 4 is a schematic diagram of adjacent channel interference provided in the embodiment of the present application, as shown in fig. 4, a wideband signal includes a target signal, a left adjacent channel signal and a right adjacent channel signal, a terminal may first obtain a signal strength RSSI of the wideband through a wideband filter, then obtain a signal strength RSSI of the left adjacent channel of the target signal and a signal strength RSSI of the right adjacent channel of the target signal through a sideband filter, and calculate a signal strength RSSI of the target signal through the following formula:
the RSSI of the target signal is the signal strength RSSI of the wideband-the signal strength RSSI of the left adjacent channel-the signal strength RSSI of the right adjacent channel.
Therefore, in this example, the terminal may obtain the signal strength RSSI of the wideband, the signal strength RSSI of the left adjacent channel and the signal strength RSSI of the right adjacent channel of the target signal through the filter, and then calculate the signal strength RSSI of the target signal through the three, which is favorable for the signal strength RSSI of the target signal.
In one possible example, the determining the relative strength of the adjacent channel interference in the target signal according to the signal strength RSSI of the target signal comprises: determining the relative interference strength of the left adjacent channel according to the signal strength RSSI of the target signal and the signal strength RSSI of the left adjacent channel; and determining the interference relative strength of the right adjacent channel according to the signal strength RSSI of the target signal and the signal strength RSSI of the right adjacent channel.
For example, the terminal may obtain the RSSI of the target signal, and obtain the RSSI of the left adjacent channel and the RSSI of the right adjacent channel, and then calculate the relative strength of the left adjacent channel interference and the relative strength of the right adjacent channel interference by the following formulas:
the relative interference strength of the left adjacent channel is the signal strength RSSI of the left adjacent channel-the signal strength RSSI of the target signal;
the relative strength of right adjacent channel interference is the signal strength RSSI of the right adjacent channel-the signal strength RSSI of the target signal.
In this example, the terminal may determine the adjacent channel interference relative strength of the target signal according to the signal strength RSSI of the left and right adjacent channels and the signal strength RSSI of the target signal, and then use the adjacent channel interference relative strength as the adjacent channel interference strength of the target signal.
In one possible example, when the relative strength of the left adjacent channel interference and the relative strength of the right adjacent channel interference are both greater than a first threshold value, the target if receiver is a zero if receiver; when the relative interference strength of the left adjacent channel is greater than a second threshold value and the relative interference strength of the right adjacent channel is less than a third threshold value, the target intermediate frequency receiver is a near-zero intermediate frequency receiver, and the frequency point is arranged on the side of the right adjacent channel; and when the relative interference strength of the right adjacent channel is greater than a second threshold value and the relative interference strength of the left adjacent channel is less than a third threshold value, the target intermediate frequency receiver is a near-zero intermediate frequency receiver, and the frequency point is arranged on the side of the left adjacent channel.
For example, when the relative strength of the left adjacent channel interference and the relative strength of the right adjacent channel interference are both greater than a threshold value Th1, the zero intermediate frequency receiver is used for receiving the target signal; when the relative interference strength of the left adjacent channel is greater than a threshold value Th2 and the relative interference strength of the right adjacent channel is smaller than a threshold value Th3, a near-zero intermediate frequency receiver is used for receiving a target signal, and a receiving frequency point is arranged on the side of the right adjacent channel; and when the relative strength of the right adjacent channel interference is greater than the threshold value Th2 and the relative strength of the left adjacent channel interference is less than the threshold value Th3, receiving the target signal by using the near-zero intermediate frequency receiver, and setting a receiving frequency point on the left adjacent channel side.
Therefore, in this example, the terminal can adaptively select the zero intermediate frequency receiver or the near-zero intermediate frequency receiver to receive the target signal and select the frequency point of the zero intermediate frequency receiver to receive the target signal according to the relative strength of the left and right adjacent channel interference of the target signal, thereby being beneficial to enhancing the adjacent channel interference suppression capability.
In one possible example, before receiving the target signal by the zero intermediate frequency receiver or receiving the target signal at the frequency point by the near-zero intermediate frequency receiver, the method further includes: and filtering the target signal through an analog filter.
In this example, before the target signal is received by the zero intermediate frequency receiver or the target signal is received at a specific frequency point by the near-zero intermediate frequency receiver, the target signal is filtered by the analog filter, so that the adjacent channel interference of the zero intermediate frequency receiver or the near-zero intermediate frequency receiver at the stage of receiving the target signal is reduced, and the adjacent channel interference suppression capability can be further increased.
In one possible example, after receiving the target signal by the zero intermediate frequency receiver or receiving the target signal at the frequency point by the near-zero intermediate frequency receiver, the method further includes: and filtering the target signal through an ACI filter.
It can be understood that, the terminal adaptively selects the frequency point at which the zero intermediate frequency receiver or the near-zero intermediate frequency receiver receives the target signal and the zero intermediate frequency receiver receives the target signal according to the adjacent channel interference strength, so that most of the adjacent channel interference in the target signal is suppressed in the receiving stage, and the adjacent channel interference can be further suppressed by matching with the ACI filter.
As can be seen, in this example, after the target signal is received by the zero intermediate frequency receiver or the target signal is received at a specific frequency point by the near-zero intermediate frequency receiver, the target signal is filtered by the ACI filter, so that the adjacent channel interference suppression capability can be further increased.
In one possible example, if the target signal is received by the near-zero intermediate frequency receiver, the method further comprises: and performing frequency mixing processing on the target signal through a frequency mixer.
It should be noted that if the terminal is a near zero if receiver, then a mixer is needed to mix the target signal.
Referring to fig. 5, fig. 5 is a flowchart illustrating another method for suppressing adjacent channel interference according to an embodiment of the present application, where the method for suppressing adjacent channel interference is applied to a terminal and includes the following operations.
Step 501, configuring a zero intermediate frequency receiver or a near-zero intermediate frequency receiver to receive a target signal according to an adjacent channel interference selector, wherein initialization configuration is that the near-zero intermediate frequency receiver receives the target signal in a left adjacent channel.
It is understood that the terminal is configured to receive the target signal by the left adjacent channel of the near-zero intermediate frequency receiver through the adjacent channel interference selector initialization. When the terminal needs to receive a target signal which is a narrow-band signal, the mutual switching between the zero intermediate frequency receiver and the near-zero intermediate frequency receiver and the mutual switching between the left and right adjacent channel frequency points of the near-zero intermediate frequency receiver are determined according to the adjacent channel interference strength of the target signal.
Step 502, filtering the target signal through an analog filter.
When the terminal needs to receive the target signal which is the narrow-band signal, the target signal which needs to be received is filtered through the analog filter, and part of adjacent channel interference is reduced.
And step 503, if the near-zero intermediate frequency receiver is configured to receive the target signal, performing mixing processing on the target signal through the mixer.
Step 504, receiving the target signal according to the zero intermediate frequency receiver or the near-zero intermediate frequency receiver configured by the adjacent channel interference selector.
That is, when the step 501 is configured such that the zero intermediate frequency receiver receives the target signal, the terminal receives the target signal through the zero intermediate frequency receiver; when the near-zero intermediate frequency receiver is configured to receive the target signal in step 501, the terminal receives the target signal through the near-zero intermediate frequency receiver.
In addition, after the terminal has received the target signal, the terminal returns to step 501 to execute the next target signal receiving process, that is, execute the step of configuring the receiver for receiving the next target signal.
And 505, filtering the target signal through an ACI filter.
The terminal adaptively selects the zero intermediate frequency receiver or the near-zero intermediate frequency receiver to receive the target signal and the frequency point of the target signal received by the zero intermediate frequency receiver according to the adjacent channel interference strength, so that most of the adjacent channel interference in the target signal is suppressed in the receiving stage, and the aim of further suppressing the adjacent channel interference can be achieved by matching with the ACI filter.
It can be seen that, according to the adjacent channel interference suppression method provided in the embodiment of the present application, the terminal can adaptively select the frequency point at which the zero intermediate frequency receiver or the near-zero intermediate frequency receiver receives the target signal and the frequency point at which the zero intermediate frequency receiver receives the target signal according to the adjacent channel interference strength, and the suppression capability of the adjacent channel interference is enhanced under the condition that the order of the filter is not changed.
