Description

一种谐波干扰的处理方法及移动终端A processing method for harmonic interference and mobile terminal

技术领域technical field

本发明涉及通信技术领域,尤其涉及一种谐波干扰的处理方法及移动终端。The present invention relates to the field of communication technology, in particular to a method for processing harmonic interference and a mobile terminal.

背景技术Background technique

谐波干扰是多频通信的射频系统所面临的一大难题,例如,LTE(Long TermEvolution,长期演进)下行载波聚合的情况下主载波发射频段的谐波干扰辅载波的接收,LTE与Wi-Fi(Wireless Fidelity)共存情况下LTE发射频段的谐波干扰Wi-Fi的接收等。而随着5G(5th-Generation,第五代移动通信技术)时代的到来,谐波干扰情况会更加严重,比如4G(4th-Generation,第四代移动通信技术)和5G进行NR(New Radio)双连接时,4G信号发射产生的谐波将会直接落在5G频段的接收带内,从而产生严重的谐波干扰。Harmonic interference is a major problem faced by the radio frequency system of multi-frequency communication. For example, in the case of LTE (Long Term Evolution, long-term evolution) downlink carrier aggregation, the harmonic interference of the main carrier transmission frequency band interferes with the reception of the secondary carrier, LTE and Wi- In the case of Fi (Wireless Fidelity) coexistence, harmonics in the LTE transmission band interfere with Wi-Fi reception, etc. With the advent of the 5G (5th-Generation, fifth-generation mobile communication technology) era, harmonic interference will become more serious, such as 4G (4th-Generation, fourth-generation mobile communication technology) and 5G for NR (New Radio) During dual connection, the harmonics generated by 4G signal transmission will fall directly in the receiving band of the 5G frequency band, resulting in serious harmonic interference.

射频系统一般包括:射频收发器、多频多模功率放大器(MMPA)、双工器(Duplexer)、天线开关(Switch)、低噪声放大器(Low Noise Amplifier,LNA)以及天线,MMPA内部包括低频(LB)功率放大器(PA,Power Amplifier)和高频(HB)功率放大器。其中,射频系统常规的谐波干扰途径如下:The radio frequency system generally includes: radio frequency transceiver, multi-frequency multi-mode power amplifier (MMPA), duplexer (Duplexer), antenna switch (Switch), low noise amplifier (Low Noise Amplifier, LNA) and antenna, MMPA includes low frequency ( LB) power amplifier (PA, Power Amplifier) and high frequency (HB) power amplifier. Among them, the conventional harmonic interference path of the radio frequency system is as follows:

干扰途径A:MMPA的低频输出主频的谐波信号,该谐波信号经过低频通路的双工器和天线开关,然后泄漏到高频的接收通路,从而影响高频的接收;Interference path A: The low-frequency output of the MMPA is a harmonic signal of the main frequency. The harmonic signal passes through the duplexer and antenna switch of the low-frequency path, and then leaks to the high-frequency receiving path, thereby affecting the high-frequency reception;

干扰途径B:MMPA的低频输出主频信号,该主频信号经过低频通路的双工器、天线开关,然后泄漏到高频的接收通路,由于高频的接收通路的LNA的非线性产生IM(intermodulation,交调)产物,其IM产物正好落在高频的接收频段内,从而影响高频的接收。Interference path B: The low-frequency output main frequency signal of the MMPA, the main frequency signal passes through the duplexer and antenna switch of the low-frequency path, and then leaks to the high-frequency receiving path. Due to the nonlinearity of the LNA of the high-frequency receiving path, IM( intermodulation, intermodulation) product, its IM product just falls in the high-frequency receiving frequency band, thus affecting the high-frequency reception.

现有技术中通常需要多种处理方案才能有效解决射频系统的谐波干扰,例如在低频的发射通路增加低通滤波器、为输出谐波信号的低频频段采用独立的PA、增大天线开关在该低频频段与高频频段的隔离度等方法,这些方法主要是从纯硬件角度出发来解决谐波干扰问题,将存在以下弊端:增加独立的低频射频PA和低通滤波器将增加射频器件成本,同时将导致射频电路过于复杂,影响布局及射频布板面积,并且也将造成MMPA内部低频的部分功能浪费。In the prior art, a variety of processing solutions are usually required to effectively solve the harmonic interference of the radio frequency system, such as adding a low-pass filter to the low-frequency transmission path, using an independent PA for the low-frequency band of the output harmonic signal, and increasing the antenna switch in the Methods such as the isolation between the low-frequency band and the high-frequency band, these methods are mainly to solve the problem of harmonic interference from the perspective of pure hardware, and will have the following disadvantages: adding an independent low-frequency radio frequency PA and low-pass filter will increase the cost of radio frequency devices , At the same time, it will cause the RF circuit to be too complex, affecting the layout and RF layout area, and will also cause waste of some low-frequency functions inside the MMPA.

综上,现有技术的谐波干扰处理方案存在射频电路复杂,成本较高的问题。To sum up, the harmonic interference processing solution in the prior art has the problems of complex radio frequency circuit and high cost.

射频谐波的产生是由于射频系统内的非线性器件的非线性造成的,射频系统内的非线性器件在正常工作时,随着其输入信号的逐渐增大,非线性器件工作将趋近于饱和区,即非线性区,此时射频系统的谐波干扰将急剧增大。本发明实施例提供一种谐波干扰的处理方法,通过控制非线性器件工作于线性区的方式,改善非线性器件工作状态的线性度,能够减小谐波干扰,提升射频性能。The generation of radio frequency harmonics is caused by the nonlinearity of the nonlinear devices in the radio frequency system. When the nonlinear devices in the radio frequency system work normally, with the gradual increase of the input signal, the nonlinear device will work close to In the saturation region, that is, the nonlinear region, the harmonic interference of the radio frequency system will increase sharply at this time. An embodiment of the present invention provides a processing method for harmonic interference, which improves the linearity of the working state of the nonlinear device by controlling the nonlinear device to work in a linear region, reduces harmonic interference, and improves radio frequency performance.

An embodiment of the present invention provides a method for processing harmonic interference, which may include the following steps:

步骤101,检测移动终端的射频系统的当前工作场景。Step 101, detecting the current working scene of the radio frequency system of the mobile terminal.

本步骤中,在移动终端处于实网工作时,检测射频系统的当前工作场景,以便于确定是否开启谐波干扰调节机制,以获取最优的射频性能。In this step, when the mobile terminal is working on a real network, the current working scene of the radio frequency system is detected, so as to determine whether to enable the harmonic interference adjustment mechanism to obtain optimal radio frequency performance.

步骤102,在移动终端的射频系统的当前工作场景发生谐波干扰时,控制射频系统内的非线性器件工作于线性区。其中,非线性器件工作于线性区时,非线性器件的输入信号和输出信号成线性相关。Step 102, when harmonic interference occurs in the current working scene of the radio frequency system of the mobile terminal, control the nonlinear devices in the radio frequency system to work in the linear region. Wherein, when the nonlinear device works in the linear region, the input signal and the output signal of the nonlinear device are linearly correlated.

本步骤中,在射频系统的当前工作场景发生谐波干扰时,通过控制射频系统内的非线性器件工作于线性区,此时,非线性器件的输入信号和输出信号成线性相关,具体的,非线性器件输入的主频信号和输出的主频信号成线性相关,输入的干扰信号和输出的干扰信号也将成线性相关,从而改善非线性器件工作状态的线性度,能够减小谐波干扰,提升射频性能。In this step, when harmonic interference occurs in the current working scene of the radio frequency system, the nonlinear device in the radio frequency system is controlled to work in the linear region. At this time, the input signal and the output signal of the nonlinear device are linearly related. Specifically, The main frequency signal input by the nonlinear device is linearly correlated with the main frequency signal output, and the input interference signal and the output interference signal will also be linearly related, thereby improving the linearity of the nonlinear device's working state and reducing harmonic interference. Improve RF performance.

本发明实施例中,通过控制非线性器件工作于线性区的方式,改善非线性器件工作状态的线性度,能够减小谐波干扰,提升射频性能;并且,本发明实施例中射频电路简单,能够节约电路设计成本。In the embodiment of the present invention, by controlling the nonlinear device to work in the linear region, the linearity of the nonlinear device's working state can be improved, harmonic interference can be reduced, and the radio frequency performance can be improved; moreover, the radio frequency circuit in the embodiment of the present invention is simple, The circuit design cost can be saved.

具体的,在本发明一个优选的实施例中,步骤102,在移动终端的射频系统的当前工作场景发生谐波干扰时,控制射频系统内的非线性器件工作于线性区的步骤,可以包括:以预设步进值增大非线性器件的工作参数至预设工作参数,控制非线性器件以增大后得到的预设工作参数工作,使非线性器件工作于线性区。也就是说,在本发明实施例中,具体可以通过调节非线性器件的工作参数,以控制非线性器件工作于线性区,改善非线性器件工作状态的线性度,从而减小谐波干扰,提升射频性能。Specifically, in a preferred embodiment of the present invention, step 102, when harmonic interference occurs in the current working scene of the radio frequency system of the mobile terminal, the step of controlling the nonlinear devices in the radio frequency system to work in the linear region may include: The working parameter of the nonlinear device is increased to the preset working parameter by a preset step value, and the nonlinear device is controlled to work with the preset working parameter obtained after the increase, so that the nonlinear device works in a linear region. That is to say, in the embodiment of the present invention, specifically, by adjusting the working parameters of the nonlinear device, the nonlinear device can be controlled to work in the linear region, and the linearity of the working state of the nonlinear device can be improved, thereby reducing harmonic interference and improving RF performance.

其中,本发明实施例中,非线性器件的工作参数可以包括非线性器件的工作电压和/或非线性器件的静态工作电流。也就是说,在本发明实施例中,可以通过提高非线性器件的工作电压,来控制非线性器件工作于线性区,从而改善非线性器件当前所处工作状态的线性度;或者,也可以通过控制非线性器件,优化调整其静态工作电流,来控制非线性器件工作于线性区,从而改善非线性器件当前所处工作状态的线性度;或者,还可以通过同时调节非线性器件的工作电压和静态工作电流,来控制非线性器件工作于线性区。Wherein, in the embodiment of the present invention, the operating parameters of the nonlinear device may include an operating voltage of the nonlinear device and/or a quiescent operating current of the nonlinear device. That is to say, in the embodiment of the present invention, the nonlinear device can be controlled to work in the linear region by increasing the operating voltage of the nonlinear device, thereby improving the linearity of the current working state of the nonlinear device; or, it can also be achieved by Control the nonlinear device and optimize its quiescent operating current to control the nonlinear device to work in the linear region, thereby improving the linearity of the current working state of the nonlinear device; or, it is also possible to adjust the operating voltage and Static operating current to control the nonlinear device to work in the linear region.

另外,由于射频系统中导致射频谐波的产生的非线性器件主要包括发射通路中的功率放大器和接收通路中的低噪声放大器,因此,本发明实施例中,非线性器件为发射通路中的功率放大器和/或接收通路中的低噪声放大器。In addition, since the non-linear devices that lead to the generation of radio frequency harmonics in the radio frequency system mainly include the power amplifier in the transmission path and the low-noise amplifier in the reception path, therefore, in the embodiment of the present invention, the non-linear device is the power amplifier in the transmission path. amplifier and/or low noise amplifier in the receive path.

另外,在本发明一个优选的实施例中,步骤102,在移动终端的射频系统的当前工作场景发生谐波干扰时,控制射频系统内的非线性器件工作于线性区的步骤,可以包括以下步骤:根据移动终端的射频系统的当前工作场景和预设的至少一个谐波干扰场景,确定移动终端的射频系统是否发生谐波干扰;移动终端的射频系统发生谐波干扰时,根据被干扰信道的信号质量,控制射频系统内的非线性器件工作于线性区。本发明实施例中,通过预先设置发生谐波干扰的至少一个谐波干扰场,然后根据当前工作场景和预设的至少一个谐波干扰场景,能够便于检测射频系统的当前工作场景是否发生谐波干扰,从而简化检测方式,提高检测效率;然后在确定射频系统发生谐波干扰时,根据被干扰信道的信号质量,确定是否开启谐波干扰调节机制,控制非线性器件工作于线性区,以改善非线性器件工作状态的线性度,从而减小谐波干扰,提升射频性能。其中,谐波干扰场景的被干扰信道可以在预设的谐波干扰场景中对应记录,也就是说,在根据当前工作场景和预设的至少一个谐波干扰场景确定射频系统发生谐波干扰时,即可同时确定当前工作场景对应的被干扰信道。In addition, in a preferred embodiment of the present invention, step 102, when harmonic interference occurs in the current working scene of the radio frequency system of the mobile terminal, the step of controlling the nonlinear devices in the radio frequency system to work in the linear region may include the following steps : According to the current working scenario of the RF system of the mobile terminal and at least one preset harmonic interference scenario, determine whether harmonic interference occurs in the RF system of the mobile terminal; when harmonic interference occurs in the RF system of the mobile terminal, according to the interference channel Signal quality, controlling the nonlinear devices in the radio frequency system to work in the linear region. In the embodiment of the present invention, by presetting at least one harmonic interference field where harmonic interference occurs, and then according to the current working scene and the preset at least one harmonic interference scene, it is convenient to detect whether harmonics occur in the current working scene of the radio frequency system interference, thereby simplifying the detection method and improving detection efficiency; then, when it is determined that harmonic interference occurs in the radio frequency system, according to the signal quality of the interfered channel, determine whether to enable the harmonic interference adjustment mechanism, and control the nonlinear device to work in the linear region to improve The linearity of the working state of nonlinear devices reduces harmonic interference and improves radio frequency performance. Wherein, the interfered channel in the harmonic interference scenario can be correspondingly recorded in the preset harmonic interference scenario, that is, when it is determined that harmonic interference occurs in the radio frequency system according to the current working scenario and at least one preset harmonic interference scenario , the interfered channel corresponding to the current working scenario can be determined at the same time.

本发明实施例中,该至少一个谐波干扰场景可以为特定的CA组合场景、特定的LTE与WiFi共存场景等。例如,至少一个谐波干扰场景可以包括:LTE的下行带间CA组合“B3A-B8A”中,B8的902.5-915MHz发射和B3的1805-1830MHz接收的工作场景;这里,B3接收频段为1805-1880MHz,B8发射频段为880-915MHz,当B8工作在902.5-915MHz时,其二次谐波频率1805-1830MHz正好落在B3的接收带内,从而影响B3的接收。再例如,至少一个谐波干扰场景可以包括:LTE B5的824-849MHz发射和WiFi 2.4G的2472-2483.5MHz的工作场景;其中,WiFi 2.4G的工作频率为2400-2483.5MHz,LTE B5发射频段为824-849MHz,当LTE B5工作在824-828MHz时,其三次谐波频率为2472-2484MHz,将会落在WiFi 2.4G工作带内,从而影响WiFi 2.4G到的工作。In the embodiment of the present invention, the at least one harmonic interference scenario may be a specific CA combination scenario, a specific LTE and WiFi coexistence scenario, and the like. For example, at least one harmonic interference scenario may include: in the LTE downlink inter-band CA combination "B3A-B8A", the working scenario of B8's 902.5-915MHz transmission and B3's 1805-1830MHz reception; here, the B3 reception frequency band is 1805- 1880MHz, B8 transmit frequency range is 880-915MHz, when B8 works at 902.5-915MHz, its second harmonic frequency 1805-1830MHz just falls within the receiving band of B3, thus affecting the reception of B3. For another example, at least one harmonic interference scenario may include: the 824-849MHz transmission of LTE B5 and the working scenario of 2472-2483.5MHz of WiFi 2.4G; wherein, the working frequency of WiFi 2.4G is 2400-2483.5MHz, and the LTE B5 transmission frequency band It is 824-849MHz. When LTE B5 works at 824-828MHz, its third harmonic frequency is 2472-2484MHz, which will fall within the working band of WiFi 2.4G, thus affecting the work of WiFi 2.4G.

另外,本发明实施例中,该被干扰信道的信号质量可以采用SINR(Signal-NoiseRatio,信噪比)表示,该SINR=有用信号/(系统噪声+干扰信号)。In addition, in the embodiment of the present invention, the signal quality of the interfered channel may be represented by SINR (Signal-Noise Ratio, signal-to-noise ratio), where the SINR=useful signal/(system noise+interference signal).

另外,本发明实施例中,在步骤102,在移动终端的射频系统的当前工作场景发生谐波干扰时,控制射频系统内的非线性器件工作于线性区的步骤之后,该谐波干扰的处理方法还可以包括:每间隔预定时间间隔,检测当前工作场景是否发生谐波干扰,在当前工作场景不发生谐波干扰时,控制非线性器件以预设参数工作。这里,通过每间隔预定时间间隔检测当前工作场景是否发生谐波干扰,并在当前工作场景不发生谐波干扰时,关闭谐波干扰调节机制,并控制非线性器件以正常的校准过程所确定的预设参数工作,该校准过程用于选择射频系统在射频指标最优时的非线性器件的工作参数。这样,能够减少谐波干扰调节机制的非必要开启,节省功耗。In addition, in the embodiment of the present invention, in step 102, when harmonic interference occurs in the current working scene of the radio frequency system of the mobile terminal, after the step of controlling the nonlinear devices in the radio frequency system to work in the linear region, the processing of the harmonic interference The method may further include: detecting whether harmonic interference occurs in the current working scene every predetermined time interval, and controlling the nonlinear device to work with preset parameters when no harmonic interference occurs in the current working scene. Here, by detecting whether harmonic interference occurs in the current working scene every predetermined time interval, and when harmonic interference does not occur in the current working scene, the harmonic interference adjustment mechanism is turned off, and the non-linear device is controlled by the normal calibration process. The preset parameters work, and the calibration process is used to select the working parameters of the non-linear device when the radio frequency index is optimal in the radio frequency system. In this way, unnecessary activation of the harmonic interference adjustment mechanism can be reduced, and power consumption can be saved.

请参见图2,其示出的是本发明实施例提供的谐波干扰的处理方法的流程示意图之二。在本发明一个优选实施例中,该谐波干扰的处理方法可以包括以下步骤:Please refer to FIG. 2 , which shows the second schematic flowchart of the harmonic interference processing method provided by the embodiment of the present invention. In a preferred embodiment of the present invention, the processing method of the harmonic interference may include the following steps:

步骤201,检测移动终端的射频系统的当前工作场景。Step 201, detecting the current working scene of the radio frequency system of the mobile terminal.

本步骤中,在移动终端处于实网工作时,检测射频系统的当前工作场景,以便于确定是否开启谐波干扰调节机制,以获取最优的射频性能。In this step, when the mobile terminal is working on a real network, the current working scene of the radio frequency system is detected, so as to determine whether to enable the harmonic interference adjustment mechanism to obtain optimal radio frequency performance.
