It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
According to research, the stray mainly comprises two types: the first is in-band spurs, mainly due to interfering signals caused by the switching spectrum and the modulation spectrum; the second type is out-of-band spurious, also commonly called harmonic spurious, which is interference generated by frequency doubling signals of main frequencies; no matter which interference signal form appears, interference may be generated on other spectrum resources, and poor user experience may be generated on other users, for example, current sound occurs during conversation, downloading speed becomes slow, or function abnormality of other user terminals is directly caused.
In the prior art, there are corresponding ways of attenuating the spurs for both of the spurs. For the in-band switching spectrum and the interference signals generated by the adjustment spectrum (i.e., in-band spurs), the rising and falling edges of the GSM spectrum can be generally optimized by adjusting the voltage level of the APC. The calibration ini file for MTK is as follows, where 255 corresponds to 3.8V split into 255 equal parts, 4 representing 3.8/255 x 4V voltage, and profile0 and profile1 representing different power levels.
Profile0 ramp down＝255,236,140,117,51,25,0,4,0,0,0,0,0,0,0，0Profile0 ramp down＝0,0,0,0,0,0,0,0，7,20,49,211,244,254,255,255Profile 1ramp down＝255,236,140,117,51,25,0,4,0,0,0,0,0,0,0，0Profile 1ramp down＝0,0,0,0,0,0,0,0，7,20,49,204,248,253,255,255
For out-of-band harmonic spurious interference signals (i.e., out-of-band spurious), a larger inductor may be connected in series or a larger capacitor may be connected in parallel to a common path of GSM, so that energy is consumed by high-frequency signals such as harmonics. This special case can attenuate the spurs by destroying the shape and appearance of the shield cover, since the harmonic spurs can also exhibit wall effects (harmonic signals propagate by coupling through the shield cover path).
It can be seen that the prior art can substantially attenuate the spurs for both out-of-band spurs and in-band spurs by both of the above schemes. However, in many cases, there is also an intermodulation interference situation in GSM, and the interference spectrum generated in this situation is also near the main frequency, so it can be regarded as another form of in-band spurs, but this form is quite special, and the problem cannot be solved basically by the above two schemes, because this is the result of intermodulation of various signals, so the spurs cannot be effectively suppressed in the prior art.
In order to solve the problem of the prior art, this embodiment provides a method for suppressing GSM in-band spurious emission, and in specific implementation, this embodiment first obtains timing information of a GSM transmission signal of a GSM terminal, and determines signal state information according to the timing information; and then determining the transmission time of the MIPI signal according to the signal state information, and finally adjusting the time sequence information according to the transmission time. According to the embodiment, the timing sequence information of the signals is adjusted, so that the problem of high-power simultaneous operation is avoided, and the stray problem can be effectively suppressed.
Exemplary method
The GSM in-band spurious suppression method can be applied to terminal equipment, wherein the terminal equipment is an intelligent terminal product such as a computer and a mobile phone. Specifically, as shown in fig. 1, the method comprises the steps of:
step S100, obtaining time sequence information of a GSM emission signal of the GSM terminal, and determining signal state information according to the time sequence information.
Because the timing sequence information of the GSM transmitting signal sent by the GSM terminal is adjusted, the simultaneous working of high power on the time axis in the whole signal transmission process can be avoided, and the problem of spurious suppression is solved. Therefore, in this embodiment, first, the timing information of the GSM transmission signal needs to be acquired, and then, the timing information is analyzed to determine the signal state information of the GSM transmission signal, so that the signal state information is analyzed in the subsequent steps to determine the state of the GSM transmission signal, and then, the timing information of the GSM transmission signal is adjusted.
In one implementation manner, in the embodiment, when determining the signal state information, the method mainly includes the following steps:
step S101, determining a transmitting signal on a time axis corresponding to the time sequence information according to the time sequence information;
and S102, acquiring signal state information corresponding to the GSM emission signal.
Specifically, the timing information in this embodiment reflects all actions on the time axis corresponding to the GSM transmit signal, so that in this embodiment, after obtaining the timing information, the time axis corresponding to the timing signal can be determined, as shown in fig. 2, the start time and stop time of the MIPI signal, the start time and stop time of the PA/ASM and other power amplifiers, and as can be seen from the time axis in fig. 2, the actions of the entire GSM transmit signal during transmission include: initialization of the MIPI signal on → PA on → GSM transmit signal transmit within the transmit time window → PA off → shutdown of the MIPI signal. Therefore, the present embodiment determines the signal state corresponding to the GSM transmission signal during the entire GSM transmission signal transmission process according to the time axis information.
And step S200, determining the transmission time of the MIPI signal according to the signal state information.
In this embodiment, after the signal status information is determined, the embodiment may determine the transmission time of the MIPI signal according to the signal status information, where the transmission time is worth of a time period between the start time and the stop time of the MIPI signal.
In one implementation, the step S200 specifically includes the following steps:
step S201, determining signal type information according to the signal state information;
step S202, determining an MIPI signal in the time sequence information according to the signal type information;
step S203, obtaining the transmission time of the MIPI signal
In specific implementation, the embodiment first determines signal type information according to the signal state information; it is possible to determine which signals are present on the entire time axis based on the signal type information. Then, the embodiment may determine the MIPI signal in the timing information according to the signal type information, and determine the transmission time of the MIPI signal based on the MIPI signal and a time axis. The embodiment determines the transmission time of the MIPI signal, which is beneficial to adjusting the whole timing sequence information in the subsequent steps, thereby suppressing the spurious.
And step S300, adjusting the time sequence information according to the transmission time.
After the transmission time corresponding to the MIPI signal is determined, the embodiment can perform comparative analysis according to the transmission time and the start time and stop time of the high-power periods such as PA/ASM, so as to adjust the whole time sequence information, thereby avoiding simultaneous operation of high power and effectively suppressing spurious.
In one implementation, the step S300 specifically includes the following steps:
step S301, determining the closing time of the MIPI signal according to the transmission time;
step S302, adjusting the closing time to realize the adjustment of the time sequence information.
As can be seen from the time axis in fig. 2, the MIPI signal is inserted before and after the PA is turned on, and intermodulation interference may be generated. In terms of time domain, the MIPI signal intervenes when the GSM Tx falls, and the power of the GSM Tx signal is still relatively high when the GSM Tx continues to fall, and the MIPI signal sends a close command at this time, so that the intermodulation interference signal is generated at the same time point. Therefore, the present embodiment may adjust the turn-off time of the MIPI signal, so that the turn-off time of the MIPI signal is delayed, thereby avoiding generating the intermodulation interference signal at the same time point. In specific implementation, the present embodiment determines the closing time of the MIPI signal according to the transmission time; the closing instruction corresponding to the MIPI signal is subjected to hysteresis processing, so that the closing time is delayed, for example, in this embodiment, MIPI OFF Timing Delay is set to 2, so that the whole Timing information is adjusted, high-power simultaneous operation is avoided, and spurious signals are effectively suppressed.
In another implementation manner, the step S300 further includes the following steps:
step S301, determining the falling edge time of the GSM emission signal according to the transmission time;
step S302, adjusting the falling edge time to adjust the timing information.
In specific implementation, the present embodiment may further determine a falling edge time of the GSM transmit signal through the transmission time, and adjust the falling edge time to advance the falling edge time, so as to avoid generating intermodulation interference signals at the same time point. Specifically, in this embodiment, the duration of the GSM transmit signal may be obtained according to the transmission time, and then the duration of the GSM transmit signal is adjusted to be smaller, so as to advance the falling edge time.
Therefore, in the embodiment, the time sequence information of the GSM transmission signal of the GSM terminal is firstly acquired, and the signal state information is determined according to the time sequence information; then, determining the transmission time of the MIPI signal according to the signal state information; and finally, adjusting the time sequence information according to the transmission time. According to the embodiment, the timing sequence information of the signals is adjusted, the phenomenon that high power works simultaneously is avoided, and the problem of stray is effectively suppressed. In addition, the embodiment does not need to replace or debug hardware, and only needs to make corresponding modification on the bottom layer of the software driver.

Therefore, in this embodiment, first, the timing information of the GSM transmission signal needs to be acquired, and then, the timing information is analyzed to determine the signal state information of the GSM transmission signal, so that the signal state information is analyzed in the subsequent steps to determine the state of the GSM transmission signal, and then, the timing information of the GSM transmission signal is adjusted.
Specifically, the timing information in this embodiment reflects all actions on the time axis corresponding to the GSM transmit signal, so that in this embodiment, after obtaining the timing information, the time axis corresponding to the timing signal can be determined, as shown in fig. 2, the start time and stop time of the MIPI signal, the start time and stop time of the PA/ASM and other power amplifiers, and as can be seen from the time axis in fig. 2, the actions of the entire GSM transmit signal during transmission include: initialization of the MIPI signal on → PA on → GSM transmit signal transmit within the transmit time window → PA off → shutdown of the MIPI signal.
