Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a communication signal processing method, which is applied to an intelligent mobile terminal.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
A method of communication signal processing, comprising: dividing the communication signal into a plurality of communication signal segments, wherein the length of each communication signal segment is a period length, calculating the signal change value of each communication signal segment, and superposing the communication signal segments and the signal segments, wherein the signal change value is greater than a preset threshold value.
As shown in fig. 1, the specific flow of the communication signal processing method may be as follows:
101. the communication signal is divided into a plurality of communication signal segments, and the length of each communication signal segment is a period length.
For example, when the communication signal of the mobile terminal changes strongly and the communication of the mobile terminal is discontinuously switched on and off, a user starts a communication signal area processing module of the mobile terminal to divide the communication signal into a plurality of communication signal segments; at this moment, the signal section with strong communication signal change is narrowed, the amplitude is reduced rapidly, the communication signal intensity of the mobile terminal is reduced, the communication of the mobile terminal is enhanced by enhancing the signal section with strong communication signal change, and the communication continuity is kept.
If the communication signal of the mobile terminal is stable, the signal change of the communication signal section tends to be stable, and the signal change between adjacent communication signal sections is not large.
The length of 1 communication signal segment is T, T represents a period length, T >. SIGMA.mT (n), T (n) is the pulse interval on the communication signal, m is the pulse quantity of the communication signal transmitted by 1 microsecond, and Sigma.mT (n) is the sum of the pulse quantity intervals of the communication signal transmitted by 1 microsecond. The whole communication signal time domain is f [ T (n) ], the interval between the signal f (T1) at the point T1 and the signal f (T2) at the point T2 is T, and is 1 communication signal segment, then the adjacent communication signal segments are f (T2) and f (T3), the interval between the signal f (T2) at the point T2 and the signal f (T3) at the point T3 is T, and so on.
Optionally, the length of 1 communication signal section can be self-defined to set up, and through the extension division to communication signal, communication signal regional processing module can detect on the whole communication signal time domain, whether the signal of arbitrary signal section changes by force.
102. And calculating the signal change value of the communication signal segment.
For example, △ f [ t (n)) ] indicates the signal variation of 1 communication signal segment, and 1 communication signal segment includes the initial signal value and the end signal value, i.e., f (t1) is the initial signal value of 1 communication signal segment, f (t2) is the end signal value of 1 communication signal segment, and △ f [ t (n)) ] is the difference between the initial signal value and the end signal value, i.e., △ f [ t (n)) ] -f (t1) -f (t2) or △ f [ t (n)) ] -f (t2) -f (t 1).
In 1 communication signal segment, the change of signal value includes rising or falling, if the signal value is rising, i.e. the signal value f (t2) at the point t2 is greater than the signal value f (t1) at the point t1, △ f [ t (n) ] ═ f (t2) -f (t1), if the signal value is falling, i.e. the signal value f (t2) at the point t2 is less than the signal value f (t1) at the point t1, △ f [ t (n)) ] ═ f (t1) -f (t2), therefore, in the embodiment of the present invention, △ f [ t n ] (m)) is set to a positive value.
103. And (4) superposing the communication signal section and the signal section when the signal change value is larger than a preset threshold value.
For example, the communication signal area processing module presets a threshold, and if the signal variation value △ f [ t (n) ] of the communication signal segment is greater than the preset threshold, the communication signal area processing module opens the signal processing system, and the signal processing system generates a signal segment, and superimposes the ending signal value of the communication signal segment and the signal value of the signal segment.
Optionally, the preset threshold may be set in a self-defined manner, the preset threshold ranges from 0.5V to 1.5V, and preferably the preset threshold is 1V, in the embodiment of the present invention, when the preset threshold is 1V and the signal variation value △ f [ t (n) ] of the communication signal segment is greater than 1V, the communication signal area processing module opens the signal processing system, and performs subsequent operations.
The length of a signal segment generated by the signal processing system is also a period length T, the length is the same as the length T of a communication signal segment, the signal of the signal segment can be in same frequency and phase with the communication signal, and can also be in same frequency and opposite phase with the communication signal, the opposite phase is equal to 180 degrees, if the signal value of the communication signal segment is sharply reduced, namely △ f [ T (n)) ] -f (T1) -f (T2), △ f [ T (n)) ] is more than 1V, the signal processing system generates a signal segment in same frequency and phase, and if the signal value of the communication signal segment is sharply increased, namely △ f [ T (n)) ] -f (T2) -f (T1), △ f [ T (n)) ] is more than 1V, the signal processing system generates a signal segment in same frequency and opposite phase.
Wherein, the end signal value of the superposed communication signal segment and the signal value of the signal segment obtain a superposed value; the communication signal area processing module presets a stable value, and when the difference value between the superposition value and the initial signal value is less than the preset stable value, the signal processing system is closed.
If the signal value of the communication signal segment is sharply reduced, superposing the communication signal segment and a signal segment with the same frequency and phase, namely adding the end signal value of the communication signal segment and the signal value of the signal segment with the same frequency and phase; if the signal value of the communication signal segment rises sharply, the communication signal segment and the signal segment with the same frequency and the opposite phase are superposed, namely the signal value of the signal segment with the same frequency and the opposite phase is subtracted from the ending signal value of the communication signal segment.
The preset stable value can be set in a self-defined mode, the range of the preset stable value is 0.1V to 0.3V, and the preset stable value is preferably 0.2V; in the embodiment of the invention, when the preset stable value is 0.2V and the difference value between the superposition value and the initial signal value is less than 0.2V, the signal processing system is closed.
And if one difference value is smaller than a preset stable value, the enhancement processing of the communication signal segment is finished, and the signal processing system is closed.
The communication signal area processing module sequentially performs subsequent processing on all communication signal segments with signal variation values larger than a preset threshold value; because the end signal value of a communication signal segment is the initial signal value of the next adjacent communication signal segment, if 1 communication signal segment is subjected to superposition processing, a new end signal value can be obtained, the new end signal value is the superposition value obtained after the communication signal segment is subjected to superposition processing, the initial signal value of the next adjacent communication signal segment is updated to the new end signal value, the adjacent communication signal segment can obtain a new signal change value, the communication signal area processing module can compare the new signal change value with a preset threshold value according to the new signal change value, whether the superposition processing is carried out on the communication signal segment is judged, and the like.
The signal values of the signal segments generated by the signal processing system are all larger than the difference value between a preset threshold value and a preset stable value; in the embodiment of the present invention, the difference between the preset threshold value 1V and the preset stable value 0.2V is 0.8V, and the signal values of the signal segments generated by the signal processing system are all greater than 0.8V.
And if the signal change value of the communication signal segment is smaller than or equal to the preset threshold value, the change of the communication signal segment is stable, and the communication signal area processing module is closed.
In order to better implement the above method, an embodiment of the present invention may further provide a communication signal processing apparatus, where the communication signal processing apparatus may be specifically integrated in a network device, and the network device may be a mobile terminal or the like.
For example, as shown in fig. 2, the communication signal processing apparatus may include a dividing unit 201, a calculating unit 202, a judging unit 203, and a superimposing unit 204, as follows:
(1) dividing unit 201
The dividing unit 201 is configured to divide the communication signal into a plurality of communication signal segments.
For example, when the communication of the mobile terminal is discontinuously switched on and off, the processor of the mobile terminal opens the communication signal area processing module, and divides the communication signal of the mobile terminal into a plurality of communication signal segments with the length of T. Through the detection to every communication signal section, communication signal regional processing module can detect the signal variation intensity of arbitrary signal section on the whole communication signal time domain, carries out subsequent processing to the communication signal section according to signal variation intensity.
(2) Computing unit 202
The calculating unit 202 is configured to calculate a signal variation value of the communication signal segment.
For example, the communication signal segment includes an initial signal value and an end signal value, the interval between the initial signal value and the end signal value is a period T, and the signal change value of the communication signal segment is a difference between the initial signal value and the end signal value, the signal change of the communication signal segment includes an increase or a decrease, if the signal value of the communication signal segment increases, the end signal value is set to be a signal value f (T2) at a point T2, and the initial signal value is a signal value f (T1) at a point T1, the signal change value △ f [ T (n) ] ═ f (T2) -f (T1) of the communication signal segment, and if the signal value of the communication signal segment decreases, the signal change value △ f [ T (n) ] ═ f (T1) -f (T2) of the communication signal segment.
(3) Judging unit 203
The judging unit 203 is configured to judge the magnitude of the signal variation value and a preset threshold.
For example, the communication signal area processing module presets a threshold, and determines the signal variation value △ f [ t (n) ] obtained by the calculating unit 202 and the preset threshold, if the signal variation value △ f [ t (n) ] is less than or equal to the preset threshold, it indicates that the signal variation of the communication signal section is stable and the signal is normal, determines the signal variation values △ f [ t (n) ] of all the communication signal sections and the preset threshold, if all the signal variation values are less than or equal to the preset threshold, it indicates that the whole communication signal is stably changed and the communication signal is normal, the communication signal area processing module is closed, and if the signal variation value △ f [ t (n) ] is greater than the preset threshold, it indicates that the signal value of the communication signal section is sharply changed and the signal enhancement processing needs to be performed on the communication signal section.
(4) Superimposing unit 204
And a superposition unit 204 for superposing the end signal value and the signal value of the signal segment.
For example, the superimposing unit 204 performs superimposing processing on all the communication signal segments obtained by the determining unit 203 and larger than the preset threshold, that is, the ending signal value of the communication signal segment superimposes the signal value of the signal segment generated by the signal processing system, so that the difference value between the obtained superimposing value and the initial signal value is within the preset stable range, and the signal change of the communication signal segment tends to be stable.
Optionally, in the communication signal processing apparatus according to the embodiment of the present invention, the superimposing unit 204 further includes a generating module and a comparing module, as follows:
(1) generation module
For example, for a communication signal segment with a signal variation value greater than a preset threshold, the communication signal region processing module opens the signal processing system, and the signal processing system generates a signal segment with a length T, where the signal of the signal segment may be a signal with the same frequency and phase as the communication signal, or a signal with the same frequency and phase opposite to the communication signal, and the determination is made according to whether the signal value of the communication signal segment is rapidly reduced or rapidly increased.
If the signal value of the communication signal segment is sharply reduced, the signal processing system generates a signal segment with the same frequency and phase, the ending signal value is superposed with the signal value of the signal segment with the same frequency and phase, and the communication signal segment obtains a new increased ending signal value; if the signal value of the communication signal segment rises sharply, the signal processing system generates a signal segment with the same frequency and the opposite phase, the ending signal value is superposed with the signal value of the signal segment with the same frequency and the opposite phase, and the communication signal segment obtains a new reduced ending signal value.
The signal values of the signal segments generated by the generation module are all larger than the difference value between the preset threshold value and the preset stable value.
(2) Comparison module
For example, the communication signal region processing module presets a stable value, compares the difference value between the superposition value of the communication signal segment and the initial signal value with the preset stable value, and if the difference value is less than or equal to the preset stable value, completes the superposition processing of the communication signal segment and closes the signal processing system.
