Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an interference-free communication method according to a first embodiment of the present invention. The anti-interference communication method provided in this embodiment may be applicable to a case of eliminating electromagnetic interference in a terminal communication process, and the method is applied to a communication terminal, and may be specifically executed by an anti-interference communication device, where the device may be implemented by software and/or hardware, and may be integrated in a terminal, referring to fig. 1, and the method in the embodiment of the present invention specifically includes:
s110, if the signal intensity of the current communication channel is smaller than the signal intensity threshold, judging whether the communication channel is interfered by the self interference source.
The signal of the communication channel is a signal that the terminal currently performs signal transmission through the communication channel, the communication channel is a channel that is allocated by the base station when the terminal performs communication and is used for the terminal to perform signal transmission, and different communication channels correspond to different signal transmission frequency bands. In the embodiment of the present invention, the signal strength threshold may be set according to an actual situation, optionally, values of sensitivities of the terminal in different states are detected, and the sensitivity is set according to the sensitivity of the terminal, where the sensitivity is the minimum signal strength that the terminal can demodulate, the sensitivities of different terminals are different, and the sensitivities of the terminals in different situations may also be different, and in addition, when the terminal is interfered by a self-interference source, the sensitivity of the terminal may be changed. For example, the values of the sensitivities of the terminal in a normal communication state, a state of being subjected to electromagnetic interference from a peripheral circuit, or the like are detected, and the value of the highest sensitivity among the values is selected as the signal strength threshold.
Specifically, when the terminal performs communication, the communication channel signal strength is weak due to interference of its own interference source on the communication channel signal transmission, but in this case, a specific interference source cannot be determined, the interference type cannot be determined, and the interference cannot be specifically eliminated. Therefore, in the embodiment of the present invention, it is determined whether the terminal is interfered in the current communication process according to the strength of the target signal, if it is determined that the strength of the current communication channel signal of the terminal is smaller than the sensitivity threshold, it is indicated that the current communication channel receives the interference, and then it is determined whether the communication channel in the current communication process of the terminal is interfered by the own interference source. Optionally, it may be determined whether the communication channel is interfered by the self-interference source according to a channel number of a channel allocated by the base station, or it may be determined whether the communication channel is interfered by the self-interference source according to a signal frequency band when the signal is transmitted through the channel, that is, it is determined whether the current communication channel is an interfered channel.
And S120, if so, adjusting the self interference source generating the interference to eliminate the interference.
The self-interference source is a circuit which generates interference to terminal communication, when the self-interference source works and signal transmission is carried out through a channel, the signal intensity is influenced or the terminal sensitivity is influenced, and the self-interference source is a self-interference source related to the interfered channel. The self interference source can be at least one of peripheral circuits of a peripheral screen circuit, a camera circuit, a charging circuit, an audio and video playing circuit and the like. One self-interference source may affect transmission signals of a plurality of interfered channels, and one interfered channel may be correspondingly affected by a plurality of self-interference sources, so that the number of self-interference sources associated with one interfered channel is at least one.
Specifically, if it is determined that the communication channel is interfered by the self-interference source, at least one self-interference source associated with the interfered channel is adaptively adjusted, so that the at least one self-interference source no longer interferes with signal transmission of the communication channel. Optionally, the self-interference source is adjusted according to the reason that the self-interference source generates interference on the channel, so that electromagnetic interference in the terminal communication process is eliminated without adding a shielding hardware device, and normal communication is realized.
According to the technical scheme of the embodiment, if the signal intensity of the current communication channel is smaller than the signal intensity threshold, whether the communication channel is interfered by the self interference source is judged; if so, adjusting the self interference source generating the interference to eliminate the interference. Whether the signal intensity of the current communication channel of the terminal is smaller than a sensitivity threshold value or not is judged, whether the communication channel is interfered by the self interference source or not is judged, when the terminal is interfered by the electromagnetic interference of the self interference source, the self interference source is adjusted, the electromagnetic interference generated by the self interference source to the terminal communication is eliminated, and the elimination of the interference of all frequency band channels is realized under the condition that a hardware structure is not required to be added.
Example two
Fig. 2 is a flowchart of an anti-interference communication method according to a second embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and details not described in detail in the present embodiment are described in the above embodiments. Referring to fig. 2, the method for interference-free communication according to this embodiment may include:
s210, if the signal intensity of the current communication channel is smaller than the signal intensity threshold value, matching the communication channel with an interfered channel in an interference channel list; and if the corresponding interfered channel is matched, determining that the communication channel is interfered by the self interference source.
Specifically, in order to determine that the cause of the interference on the signal strength of the communication channel is electromagnetic interference of its own interference source, it is determined whether the communication channel is an interfered channel. After the base station allocates the communication channel, the identification information of the communication channel is acquired, the identification information of the communication channel is matched with the identification information of the interfered channel in the interference channel list, and if the matching is successful, the communication channel is the interfered channel and is interfered by the self interference source.
The list of interfering channels is built up as follows: detecting a first sensitivity and a second sensitivity when a terminal receives signals through each communication channel, wherein the first sensitivity is the sensitivity when the terminal receives the signals through the same communication channel when a target self interference source is in a working state, and the second sensitivity is the sensitivity when the target self interference source is in a non-working state and the terminal receives the signals through the same communication channel; the target self-interference source is a current self-interference source to be detected obtained by traversing at least one self-interference source; if the difference value between the first sensitivity and the second sensitivity is larger than the difference threshold value, determining that the communication channel belongs to an interfered channel; and recording the interfered channel and the self interference source associated with the interfered channel into the interference channel list. Before judging whether the communication channel is interfered by the self interference source, the method further comprises the following steps: and receiving the interference channel list and storing the interference channel list to the local terminal.
Specifically, the target self-interference source is a self-interference source which is obtained by traversing at least one self-interference source and is used as a detection object during detection, when the target self-interference source generates electromagnetic interference in the terminal communication process, the sensitivity of the terminal is affected, so that the sensitivity of the terminal is changed, therefore, a first sensitivity of the terminal when the target self-interference source is in a working state and performs signal transmission through the same channel is detected, and a second sensitivity of the terminal when the target self-interference source is in a non-working state and performs signal transmission through the channel is detected, a difference value between the first sensitivity and the second sensitivity is calculated, if the difference value is greater than a difference value threshold value, the influence of the self-interference source during working on the sensitivity of the terminal during signal transmission through the channel is considered to be greater during the terminal communication process, and the channel is determined as an interfered channel, and associating the target self-interferer with the interfered channel. The above tests are respectively performed for different self-interference sources and different channels to obtain an interference channel list. By establishing the interference channel list, the interfered type and the self interference source of the terminal can be always and accurately judged in the communication process of the terminal, so that the adaptation adjustment is convenient to eliminate the electromagnetic interference, and the normal communication of the terminal is ensured.
S220, searching self interference sources corresponding to the matched interfered channels in the interference channel list, wherein the interference channel list also comprises self interference sources which generate interference on each interfered channel.
Specifically, since the interfered channel and the self-interference source generating interference to the interfered channel are associated in the interference channel table, after the interfered channel corresponding to the communication channel is determined, the self-interference source associated with the interfered channel can be determined.
And S230, adjusting the searched at least one self interference source to eliminate interference.
Optionally, adjusting the self-interference source generating interference to eliminate interference includes: and adjusting the clock frequency of the searched at least one self interference source to eliminate the interference. The interference generated by the self interference source to the communication channel signal transmission is generally the frequency multiplication of the clock frequency of the self interference source and the frequency of the communication channel signal are consistent, so that the interference is generated to the transmission, the reception and the demodulation of the communication channel signal, therefore, when the communication channel is judged to be the interfered channel, the clock frequency of at least one self interference source associated with the interfered channel is adjusted, so that the current frequency multiplication of the self interference source is inconsistent with the frequency of the communication channel signal, and the electromagnetic interference of the self interference source to the communication channel is eliminated.
S240, if the channel signal is not detected currently, the clock frequency of the target self interference source is recovered to the initial clock frequency.
Specifically, if no channel signal is detected currently, it is indicated that the terminal does not perform communication at this time, and there is no signal transmission process, therefore, in the embodiment of the present invention, when the terminal does not perform communication, the clock frequency of the self-interference source is restored to the initial clock frequency, so that when the clock frequency of the self-interference source is adjusted again, the initial clock frequency is used as a reference, and the reliability of the interference channel list is maintained, thereby avoiding a change in the reference clock frequency of the self-interference source, which causes a change in an association relationship between an interfered channel in the interference channel list and at least one self-interference source.
According to the technical scheme of the embodiment of the invention, the interfered type and the self interference source of the terminal can be always and accurately judged in the communication process of the terminal by establishing the interference channel list, so that the adaptation adjustment is convenient to eliminate the electromagnetic interference, and the normal communication of the terminal is ensured. And the clock frequency of the self interference source is adjusted, so that the current frequency multiplication of the self interference source is inconsistent with the frequency of the communication channel signal, and the electromagnetic interference of the self interference source on the communication channel signal transmission is eliminated.
