具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
示例性的，本申请实施例应用的通信系统100可以如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与UE120(或称为通信终端设备、终端设备)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的UE进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的网络设备(Base Transceiver Station，BTS)，也可以是WCDMA系统中的网络设备 (NodeB，NB)，还可以是LTE系统中的演进型网络设备(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
在5G网络部署初期，由于频段较高、传播损耗较大等原因，很难做到短时间内全覆盖，同时出于抢占5G竞争先机的需要，大部分国内外运营商当前采用非独立组网方案或者非独立组网、独立组网方案并举。若5G网络按非独立组网架构部署，则要求终端设备支持双连接技术，采用双射频同时连接4G与5G网络并进行双收双发，此时射频器件非线性等因素容易导致终端设备存在自干扰问题，这里的非线性干扰主要是谐波干扰、互调干扰以及混频干扰，其中互调干扰是影响较大的干扰之一，如何解决互调干扰是5G和4G LTE联合组网的一个关键问题。互调干扰信号受产生影响的原始信号数量可以分为二阶、三阶等多阶互调干扰信号，本申请提供的方案主要针对其中功率最大的二阶互调干扰信号进行处理。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。

也就是说，本实施例提供的方案中，终端设备在进入通信阶段的时候，采用训练阶段产生的控制参数进行控制对干扰进行消除；一旦对干扰消除的效果无法满足第一预设条件，那么就进入校准阶段，在校准阶段得到新的控制参数，该新的控制参数使得干扰消除的效果满足第一预设条件；然后终端设备再回到通信阶段采用新的控制参数进行干扰消除。

所述方法还包括：所述终端设备采用基于第二控制参数生成的第二对消信号对接收的通信信号进行干扰消除，得到所述干扰消除结果；

与前述第一幅度或相位要求类似的，所述第二幅度要求还可以包括幅度近似相同；第二相位要求还可以包括相位近似相反。具体的可以与前述类似，这里不再进行赘述。
总的来说，本实施例提供的方案中包含有训练阶段、通信阶段、校验阶段三种阶段的处理，比如，参见图3，工作时序分为训练阶段、正常工作阶段和校准阶段。
其中，正常通信阶段主要采用训练阶段或校准阶段得到的第二控制参数或第一控制参数来进行干扰消除；而训练阶段以及校准阶段则主要用于得到第二控制参数以及第一控制参数。

所述终端设备停止收发通信信号，基于训练信号得到所述第二控制参数；其中，所述训练信号为一个参考信号序列。
其中，所述训练信号可以为：基于ZC序列生成的参考信号序列、或者是一个AWGN信号等。
以及校准阶段的处理，可以为：
所述终端设备保持通信信号的收发，基于当前接收的通信信号中的带有干扰的发射信号得到第一控制参数。
其中，所述带有干扰的发射信号，可以为带有互调干扰的发射信号。
其中，得到第二控制参数的方式，包括：
将训练信号进行第一迭代处理；
若第一约束条件被满足，将所述训练信号对应的幅度、相位的调节系数确定为所述第二控制参数；其中，所述第一约束条件包含收敛误差达到第一预设门限值。
得到第一控制参数的方式，包括：
将当前接收的通信信号中的带有干扰的发射信号进行第二迭代处理；
若第二约束条件被满足，将所述当前接收的通信信号中的带有干扰的发射信号对应的幅度、相位的调节系数确定为所述第一控制参数；
其中，所述第二约束条件包含收敛误差达到第二预设门限值。
其中，所述第一迭代处理的处理次数不低于第二迭代处理的处理次数；并且第一预 设门限值不高于第二预设门限值。
前述第一迭代处理和第二迭代处理，可以采用如最小二乘、最大似然准则等处理，这里不做赘述。
所述第一约束条件以及第二约束条件，可以理解为收敛误差满足门限，也就是前述第一预设门限以及第二预设门限；可以分别设置为如第一预设门限delta＝0.1，或者，设置为第二预设门限为1，这也是训练和校准的核心不同之一。
也就是说，在迭代处理中，可以存在两个限制条件，一种为所要达到的门限值，或者称为门限值，另一种是迭代次数的限制。
换句话说，在进行迭代处理过程中，要么需要达到设置的门限值，此时不对迭代次数进行限定，无论进行多少次迭代处理，只要能达到要求的门限值为止；再一种，就是需要达到对应的迭代次数，只要完成对应的迭代次数的迭代处理，无论是否最终达到了目标门限值，均可以认为结束处理。
分别来说，前述训练阶段与校准阶段虽然都用了迭代处理，并且均设置有相应的门限值，但是，训练阶段的迭代处理次数设置的比校准阶段的迭代次数要多，或者，训练阶段设置的门限值与校准阶段设置的门限值是不一样的。训练阶段由于更加要求精度，因此，其门限值(也就是门限值)可以比校准阶段的门限值设置的更加严格，或者，训练阶段要求的迭代次数多于校准阶段要求的迭代次数。
如此，训练阶段得到的结果也就是控制参数，是比校准阶段得到的控制参数对干扰消除的效果更优的。
再进一步地，前述门限值可以为门限集合，其中每一个门限均可以认为是一个子门限，不同子门限对应不同次的迭代处理，相邻次的子门限可以相同或者不同。
举例来说，前述校准阶段的迭代处理，如果采用门限值作为限制因素，每一次迭代处理可以设置对应的子门限，并且，每一次迭代处理对应的子门限不同。比如，可以为第n次迭代处理对应的子门限(或子门限值)低于第n+1次迭代处理对应的子门限(或子门限值)。其中，n为大于等于1且小于N的整数。
相应的，训练阶段的迭代处理，如果采用门限值作为限制因素，每一次迭代处理对应的子门限也可以不同。比如，训练阶段的第m次迭代处理对应的子门限小于第m+1次迭代处理的子门限；m为大于等于1且小于M的整数。
也就是说，除了最终设置的门限值之外，每一次迭代处理还可以对应子门限。
本实施例中，N可以为2，也就是校准阶段可以仅执行两次迭代处理；M可以大于2，也就是训练阶段可以执行3次及以上的迭代处理。
还需要指出的是，在以次数为限制因素的迭代处理中，同样可以包含门限值，但是可以不以是否达到门限值作为最终的收敛条件。
校准阶段以及训练阶段使用的算法可以相同也可以不同，比如迭代算法可以不同或相同。
可以理解为，校准阶段主要保证的是时效性，而训练阶段主要保证的是准确性。也就是，校准阶段可以将相应的门限值设置的要求降低，使得终端设备能够更快速的计算得到相应的第一控制参数。而训练阶段主要要得到更优的去干扰效果，那么可以设置的门限值要求更高，也就是得到更好的去干扰结果，因此，可以增加迭代次数来达到对应的门限值。
再进一步地，结合图4，对校准阶段的处理进行说明：
步骤31：所述终端设备保持通信信号的收发，若所述终端设备采用基于所述第一控制参数生成的第一对消信号对所述接收信号进行干扰消除的消除结果不满足第二预设条件；
步骤32：则所述终端设备停止收发通信信号，采用调整后的训练信号得到调整后的第二控制参数。
通过前述处理，可以看出，经过校准阶段的迭代处理，可能并无法得到对通信信号的干扰信号功率消除达到第二门限值的控制参数，那么，参见图2，可以由校准阶段直接退回到训练阶段。
这里需要指出的是，不同次训练阶段的处理中，采用的训练信号与对应的通信环境相关。比如，可以结合当前的空口情况或者其他的情况，重新生成每一次训练阶段所对应的训练信号来进行后续训练，这样，能够得到更加符合当前通信环境(或空口要求)的第二控制参数。具体的训练阶段的处理与前述相同，这里不再赘述。
再进一步地，在执行前述步骤31的采用当前接收的通信信号进行迭代处理之前，还可以包括：
若候选控制参数中存在满足对所述通信信号的干扰信号功率消除达到第二门限值的控制参数，则将所述控制参数作为所述第一控制参数；
否则，所述终端设备保持通信信号的收发，基于当前接收的通信信号中的带有干扰的发射信号得到第一控制参数。
当然，如果终端设备未存储至少一个控制参数，那么可以不执行上述处理，直接执行前述步骤31～步骤32。
如果终端设备中存储了一个或多个候选控制参数，那么可以从中查找是否存在能够将通信信号的干扰信号功率消除至第二门限值的控制参数；若不存在，则执行前述步骤31～步骤32；若存在，则直接将查找到的控制参数作为所述第一控制参数。如此，能够进一步节省处理资源，提升校准阶段的处理效率。
前述终端设备存储的至少一个候选控制参数，可以为预先设置的，或者，可以为训练阶段训练得到除第二控制参数之外的一个或多个控制参数。举例来说，在训练阶段可以得到多个控制参数，将其中消除干扰的效果最优的作为第二控制参数，剩余的控制参数存储在终端设备中作为候选，也就是作为前述校准阶段的候选的至少一个控制参数。
结合图5，对本实施例提供的方案的处理流程进行整体说明：
步骤41：终端设备进入非通信阶段前，先进入训练阶段，在所述训练阶段采用精度较高但效率较低的参数搜索第一算法，得到本次训练对应的最优控制参数，也就是第二控制参数；
其中，第一算法相对于校准阶段的算法而言，为效率较低但是准确性较高的一种参数搜索算法，可以为：将训练信号输入至训练模型，进行迭代处理，得到第二控制参数。具体的说明与前述相同，这里不再赘述。
本步骤计算得到的第二控制参数，在通信阶段可以直接使用，也就是得到所述第二控制参数之后，也就是得到满足一定消除效果的控制参数，所述终端设备进入通信阶段，并且使用所述第二控制参数生成对消信号进行干扰消除。
步骤42：所述终端设备进入通信阶段后，如果由于通信环境的变化和突然恶化通信等原因导致当前的最优参数不在适用、或是一个次优的参数，终端设备自行触发进入校准阶段。
步骤43：所述终端设备从存储的控制参数中查找是否存在满足第二门限值的控制参数，或者，可以理解为，所述终端设备从存储的控制参数中查找是否存在满足第一消除效果的控制参数；若存在满足第一消除效果的控制参数，则将该控制参数作为第一控制参数，由校准阶段返回至通信阶段，采用第一控制参数进行通信信号的干扰消除处理；若不存在，则执行步骤44。
步骤44：采用实际工作信号和当前的参数，使用精度较低但效率较高的参数搜索第 二算法，得到对应的控制参数；
其中，第二算法相对于训练阶段的第一算法而言，为效率较高但是准确性较低的一种参数搜索算法，具体的可以为：所述终端设备保持通信信号的收发，将当前接收的通信信号输入至校准模型进行迭代处理，得到第一控制参数。具体的与前述相同，这里不再赘述。
步骤45：判断得到的所述控制参数是否为满足第二消除效果的控制参数，若满足，则将控制参数作为第一控制参数，重新进入通信阶段，采用所述第一控制参数进行干扰消除；否则，返回步骤41。
本步骤中第二消除效果与前述第一消除效果可以相同可以不同。
举例来说，可以将当前的通信信号以及相关参数带入校准模型进行1次或2次迭代处理，并做门限判断(这两次迭代的门限可以相同或不同，第二次可以更严格)，如果满足则直接输出参数给通信阶段，不满足返回训练阶段、重新进入训练过程。
结合前述方案，下面结合图6，根据终端设备内包含的部件及其对应的功能进行详细说明：
所述终端设备获取训练信号，或当前发射的通信信号中的带有干扰的发射信号；
其中，所述基于第二控制参数或基于第一控制参数生成第一对消信号或第二对消信号的处理，包括：
采用所述第二控制参数或所述第一控制参数对所述参考信号进行调幅和/或调相处理得到所述第一对消信号或所述第二对消信号。
前述发射的通信信号中的带有干扰的发射信号，可以包括有二阶互调干扰，和/或三阶互调干扰，和/或更多阶的互调干扰，本实施例中均可以包含，这里不再一一列举。
也就是说，从发射端分离出一部分带有互调干扰的发射信号作为参考信号，经过调幅调相处理构建出对消信号，并最终抵消掉接收信号中的互调干扰信号。
具体的，针对其中第一部件的处理进行说明，可以包括：
所述终端设备基于从所述终端设备的信号发射端分离出的原始信号；
基于所述原始信号的功率，从至少一条抑制链路中选取与所述原始信号的功率匹配的第一抑制链路，原始信号经过所述第一抑制链路后得到所述带有干扰的发射信号。
需要指出的是，第一部件中的至少一条抑制链路与原始信号的功率之间可以存在对应关系。具体的，可以为预设原始信号的功率与抑制链路之间的对应关系列表来实现。
一种示例中，第一部件中存在两条抑制链路，可以根据原始信号的功率是否大于预设门限值来确定其对应的抑制链路，比如，当原始信号的功率大于预设门限值的时候，可以对应采用第一抑制链路，否则采用第二抑制链路。
另一种示例中，第一部件中可以存在三条及以上的抑制链路，那么可以设置抑制链路1对应的功率阈值为A，抑制链路2对应功率阈值B，抑制链路3对应功率抑制C。
一种示例中，结合图7对本实施例提供的第一部件存在两条抑制链路的第一部件进行说明，终端设备使用耦合器从功率放大器(图中的功放输出)之后的射频信号中分离出一部分信号，并从中提取出其中的互调干扰信号(比如可以为二阶互调干扰信号)，作为后续构建对消信号所需的参考信号。为了不影响信号正常发送，从这里分离的信号功率不能太大，否则可能造成发射信号损耗过大影响之后的发射链路工作。其中，分离出的发射信号中包含原始发射信号、二阶互调干扰信号、和其它各阶干扰信号。
然后，将分离出的这部分信号中原始发射信号的残留称为原始信号，这里需要先通过滤波器滤除其中的原始信号，否则残存的原始信号不仅会使得后面对消链路的对消信号产生变得困难，也可能被引入接收链路造成干扰。为了消除这部分原始信号，应该使用性能足够好的滤波器，或者使用串联滤波器组的方法实现足够的抑制性能，考虑到实 际滤波器的性能限制，串联滤波器组的方案往往更可行。实际通信中，发射信号的功率存在变化，如果只使用一条链路抑制分离出的原始信号，则这条链路上设置的滤波器应该足够抑制发射信号功率最大时的原始信号功率。但是在另一方面，由于分离信号中的二阶互调干扰信号功率比原始信号低很多，而同时分离信号本身的功率也只是原始信号的一小部分，这导致分离出的二阶互调功率信号功率往往很低。在仅仅使用一条抑制链路而发射信号功率又较低的时候，功率本身较低的二阶互调信号收到多个滤波器的通带损耗影响，导致功率会进一步降低，进而影响后面对消链路生成对消信号的效果。因此，在信号分离部分设计了两条抑制链路(如图中所示两条链路)，通过射频开关进行线路切换，当发射信号功率较低的时候选用滤波器较少的抑制链路(比如图中射频开关#1和滤波器1组成的链路)，减少二阶互调干扰信号受到的损耗衰减，当发射信号攻略较高的时候选择滤波器较多的抑制链路(如图中射频开关#2、滤波器1、2组成的链路)，提高抑制效果。
另外，如图6所示，本实施例提供的方案中，还包括第二部件，结合第二部件进行其进行的处理的说明：
所述第二部件中包含至少一条对消链路，所述至少一条对消链路相互并联或相互串联；并且，每一条所述对消链路中包含有射频开关、衰减器以及移相器，所述至少一条对消链路中的部分对消链路中还包括滤波器；
所述采用所述第二控制参数或所述第一控制参数对所述参考信号进行调幅和/或调相处理得到所述第一对消信号或所述第二对消信号，包括：
所述终端设备基于第二控制参数或第一控制参数确定所述至少一条对消链路中所需开启的至少部分对消链路，通过所述第二控制参数或第一控制参数控制所述至少部分对消链路将所述参考信号的幅度调整至与接收的通信信号中的干扰信号的幅度相同、并且控制至少部分对消链路将所述参考信号的相位调整至与所述接收的通信信号中的干扰信号的相位相反，得到所述第一对消信号或第二对消信号。
关于前述不同对消链路中包含的衰减器的衰减幅度可以相同可以不同。在部分具备滤波器的对消链路中，不同的链路对应的滤波器可以存在类型不同，比如，带通、低通、高通等类型的滤波器，可以在不同的对消链路中根据实际需要进行设置。
第一部件，即发射侧，选择某个抑制链路，只需要基于功率；第二部件，即接收侧，选择某个反馈链路，需要基于功率(衰减器)和相位(移相器)。
另外，不同的对消链路中，关于滤波器的通带的中心频点以及带宽，可以由前述第二控制参数或第一控制参数来确定。
进一步地，基于前述训练阶段或校准阶段可以得到对应的第二控制参数或第一控制参数。具体来说，控制参数中均可以包括有以下内容至少之一：不同对消链路的开启或关闭；开启的对消链路中衰减器的衰减值(或衰减幅度值)；开启的对消链路中移相器的移相值；开启的对消链路中如果包含至少一个滤波器，那么还包括有所述至少一个滤波器的通带频率范围。
一种示例中，结合图8、9对第二部件进行说明；
第二部件可以称为消信号产生模块，用于构建与干扰信号幅度相同相位相反的对消信号。该模块由2、3或者更多对消链路构成，每条链路都有一个射频开关控制链路工作状态，一个移相器和衰减器调整信号输出，第2、3条链路增加一个滤波器用来处理一些特殊情况。
输入整个对消模块的信号包含二阶互调干扰信号和一些其它阶互调干扰信号，首先经过低噪放大器(LNA)放大提高参考信号功率，再将放大后的信号输出到不同链路。第一条对消链路对参考信号整体进行处理，主要针对其中的二阶互调干扰信号进行调幅调 相操作。第二、三条对消链路的滤波器设置根据实际情况进行选择。原始信号中存在二阶互调信号以外的其它阶互调干扰信号，这些信号大部分功率比二阶互调信号弱，或者频率相隔较远，往往被滤除在分离模块的滤波器通带之外。但是依然可能存在某阶互调信号频段在二阶互调信号附近，进入分离模块的滤波器通带。当这部分残存互调干扰信号功率较高时，可以设置第2、3条对消链路滤波器通带为这些信号中心频点，使用2、3路对消链路构建这些残存互调信号的对消信号，最终将其消除。当二阶互调干扰信号周围没有其它残留互调干扰信号存在，或者残留信号功率远低于二阶互调干扰信号时，可以关闭这两条链路，或者将第2、3条消除链路的通带设置为二阶互调干扰信号中心频点，进一步提高消除效果。
实际工作中，二阶互调干扰信号的功率相对较小也比较稳定，可以在训练阶段先将其范围控制在衰减器中值附近。在实际通信状态中，环境因素会导致干扰信号有一定程度的幅度变化，这时候由中控芯片控制可调衰减器的衰减幅度，调整对消信号的幅度与干扰信号相同，再通过移相器调整对消信号的相位与干扰信号相反，最后产生出可以实现干扰抵消的对消信号。
图8示出的为多条对消链路并行的一种方式，其中，开启三条对消链路中的哪一条或哪几条，可以通过第二控制参数或第一控制参数来确定；图9示出两种对消链路串行的方式，一种是直接确定采用两条串行的对消链路，关于哪几条链路进行串行处理，同样可以通过第二控制参数或第一控制参数来确定，最终通过串行的对消链路得到输出的对消信号；图9中下方示出的则为基于主控部件或反馈控制部件来对一条对消链路输出的对消信号先进行对消的效果判断，如果不满足要求，那么反馈控制部件再选出下一条对消链路进行处理，直至得到满足对消效果的对消信号为止。
本示例中，满足对消效果可以理解为接收信号中的干扰值低于对应的门限值(比如前述的第一门限值或第二门限值)。
进一步地，本实施例还提供了主控部件，或者可以称为反馈控制件(如图6中所示)，其处理包括：
所述终端设备将第一或第二对消信号在接收端与接收信号进行对消处理；
所述终端设备的接收端采集至少一个采集点的功率或/和相位，基于采集到的信号功率或/和相位选择对消处理后的信号对应的至少一条反馈链路，以得到调整后的第一或第二对消信号。
其中，关于训练阶段以及校准阶段的迭代处理与前述方案相同，这里不再赘述。
一种示例中，如图10所示为主控部件的组成结构，用以检测叠加消除后信号的功率，为反馈控制提供参考。使用耦合器从叠加消除后的射频链路中耦合出一部分，由于功率检波器不能区分检测信号的频率，所以先使用滤波器将目标干扰信号频率以外的信号滤除出去，仅仅留下二阶互调干扰信号所在频段。这样功率检波器检测出的信号功率主要就是叠加消除后该干扰信号的功率了，直接反应了消除效果。考虑到消除叠加后的干扰信号功率范围可能存在较大波动，在功率检波器前加入了固定增益放大器和可调衰减器，以匹配功率检波器的量程。功率检波器将测量的信号功率转换成电压，通过ADC芯片转换成数字信号发送给主控芯片进行控制计算。
其中，接收端采集至少一个采集点可以为在发射端、对消链路与输出端，在这些采集点分别进行功率采集得到的信号，主控芯片用采集到的功率作为参考，也就是基于采集到的信号功率和/或相位选择对消处理后的信号对应的至少一条反馈链路，已得到调整后的第一或第二对消信号。
在实际应用时，前述第一部件、第二部件以及主控部件，可以体现为终端设备中的分离链路、对消链路以及反馈控制，比如参见图11所示，其名称与图6不同，但是实 现的功能可以是相同的，因此不再进行赘述。
在一种示例中，结合图6或图11来说，本实施例提供的方案可以将工作时序分为训练阶段、正常工作阶段和校准阶段。训练阶段存在于终端设备开机与空闲时段，在该阶段内，终端设备部接收远端有用信号，此时接收端仅仅接收到发射端泄露的互调干扰信号，该阶段终端设备接收到的是较为纯净的干扰信号，比较有利于寻找到消除控制的最优参数。当对消信号产生模块中有多条对消链路时，主控芯片通过射频开关先打开第一条对消链路，关闭其余链路，寻找出这个链路单独工作时的最优参数。然后打开第二条链路，寻找出两条链路同时工作时的最优参数，后面的链路依次打开直到找到所有链路同时工作时的最优参数，即完成训练阶段。正常通信阶段时终端设备正常收发信号，同时主控芯片通过反馈模块监测干扰消除效果。如果检测到干扰消除效果出现严重下降，则停止正常通信阶段进入校准阶段。校准阶段中，主控芯片根据算法快速寻找到合适的控制参数，提高消除效果，使得终端设备能够尽快恢复到正常通信阶段。如果校准阶段不能找到合适的控制参数，则回到训练阶段重新寻找最优控制参数。
基于前述说明，本实施例提供的一种示例中，可以包括：
假设环境中的底噪功率为-100dBm，二阶互调干扰功率为-60dBm，接收端如果需要正常工作，需要将互调干扰功率至少消除到-80dBm。消除装置工作在训练阶段的时候，通过控制算法寻找最优的消除效果，此过程时间花费可以相对较长，寻找到最优控制参数c0，使得消除装置可以将互调干扰功率消除到-95dBm。之后设备进入正常通信阶段，此时消除装置实时监控干扰信号的功率，如果功率高于某个设定的门限值，则进入校准阶段。例如设门限值T为-85dBm，则设备在正常通信阶段由于环境变化导致干扰功率高于-85dBm的时候，消除装置进入校准阶段，校准阶段不停止设备的通信收发，通过两个步骤寻找满足将干扰信号功率消除到小于T的控制参数c1，这个过程以追求效率为目的，c1的效果可能不是最优的，仅仅满足将干扰信号功率抑效果达到正常通信要求。如果校准阶段无法找到满足条件的控制参数，此时正常通信收发已经无法有效保证了，则消除装置回归到训练阶段，重新寻找控制参数。
综上，训练和通信之后增加校准为本申请的主要处理思路。其中，训练信号可以是干净的，模型也比较理想；采用当前的最优参数集(也就是第二控制参数，可以包括有每一个滤波器、功放等的系数等内容)，进入通信阶段；在进入通信阶段进行处理时，如果因为移动进入恶劣环境，发生了变化，那么就触发进行校准；在校准阶段可以设置门限值，采用实际通信信号，进行校准处理；如果校准之后无法满足要求，则终端设备通信停止，进行再次训练。
可见，通过采用上述方案，就能够在训练之后基于得到的控制参数，在通信阶段进行干扰消除，并且在其基础上，增加校准阶段以优化提升通信的性能、保证趋近最优消除效果。
另外，本实施例提供的方案，还可以采用消除电路产生抵消信号叠加的方法消除终端设备中的互调自干扰，以及采用两条抵消链路的架构优化分离模块的性能，减小参考信号收到的损耗。其中，在对消链路还能够增加额外滤波器，应对互调干扰模块周围可能存在的其它残留互调干扰信号。因此，本实施例提供的方案尤其适用于在5G双链接结构下，终端设备中的非线性器件会产生互调干扰信号，对接收端造成自干扰，自干扰信号功率在底噪以上40dB左右，影响通信系统正常工作的情况，终端设备中使用本方案后，可以在一定程度上消除互调干扰的影响。与原有的互调干扰抑制架构相比，本实施例提供的方案能够通过校准阶段而自适应调节对消信号，实时保持最佳自干扰抑制，可适应复杂多变的移动设备环境。此外，本装置不用针对某种器件做单独优化，以及工作在接收端前，可以与之前的多种设置在发射端的消除方法并存，进一步提升消除效果。
本发明实施例提供了一种干扰消除装置，如图12所示，包括：
主控部件1201，若接收信号的干扰消除结果不满足第一预设条件，则获取第一控制参数，所述第一控制参数基于接收的通信信号生成；采用基于所述第一控制参数生成的第一对消信号对所述接收信号进行干扰消除，所述第一对消信号与当前接收的通信信号中的干扰信号的幅度满足第一幅度要求、相位满足第一相位要求。
所述第一预设条件为优于最低指标要求的要求；
其中，所述最低指标要求由协议规范定义，包括：通信性能的最低指标要求。
另外，主控部件1201，采用基于第二控制参数生成的第二对消信号对接收的通信信号进行干扰消除，得到所述干扰消除结果；
其中，所述第二控制参数基于训练信号生成，所述第二对消信号与当前接收的通信信号中的干扰信号的幅度满足第二幅度要求、相位满足第二相位要求。
总的来说，本实施例提供的方案中包含有训练阶段、通信阶段、校验阶段三种阶段的处理，比如，参见图3，工作时序分为训练阶段、正常工作阶段和校准阶段。
具体来说，所述主控部件，停止收发通信信号，基于训练信号得到所述第二控制参数；其中，所述训练信号为一个参考信号序列。
所述主控部件，将训练信号进行第一迭代处理；若第一约束条件被满足，将所述训练信号对应的幅度、相位的调节系数确定为所述第二控制参数；其中，所述第一约束条件包含收敛误差达到第一预设门限值。
所述主控部件，保持通信信号的收发，基于当前接收的通信信号中的带有干扰的发射信号得到第一控制参数。
所述主控部件，将当前接收的通信信号中的带有干扰的发射信号进行第二迭代处理；
若第二约束条件被满足，将所述当前接收的通信信号中的带有干扰的发射信号对应的幅度、相位的调节系数确定为所述第一控制参数；
其中，所述第二约束条件包含收敛误差达到第二预设门限值。
所述第一迭代处理的处理次数不低于第二迭代处理的处理次数；并且第一预设门限值不高于第二预设门限值。
这里需要指出的是，再次回到训练阶段与初始的训练阶段的处理流程可以相同，但是采用的训练信号可能不同。
再进一步地，所述主控部件1201，采用基于所述第一控制参数生成的第一对消信号对所述接收信号进行干扰消除的消除结果不满足第二预设条件；则停止收发通信信号，采用调整后的训练信号得到调整后的第二控制参数。以及，若候选控制参数中存在满足对所述通信信号的干扰信号功率消除达到第二门限值的控制参数，则将所述控制参数作为所述第一控制参数；否则，保持通信信号的收发，基于当前接收的通信信号中的带有干扰的发射信号得到第一控制参数。
结合前述方案，下面结合图6，根据终端设备内包含的部件及其对应的功能进行详细说明：
所述装置还包括：第一部件1202，获取训练信号，或当前发射的通信信号中的带有干扰的发射信号；
第二部件1203，采用所述第二控制参数或所述第一控制参数对所述参考信号进行调幅和/或调相处理得到所述第一对消信号或所述第二对消信号。
具体的，第一部件1202，基于从所述终端设备的信号发射端分离出的原始信号；基于所述原始信号的功率，从至少一条抑制链路中选取与所述原始信号的功率匹配的第一抑制链路，原始信号经过所述第一抑制链路后得到所述带有干扰的发射信号。
另外，如图6所示，本实施例提供的方案中，还包括第二部件，结合第二部件进行 其进行的处理的说明：
所述第二部件中包含至少一条对消链路，所述至少一条对消链路相互并联或相互串联；并且，每一条所述对消链路中包含有射频开关、衰减器以及移相器，所述至少一条对消链路中的部分对消链路中还包括滤波器；
所述第二部件，基于第二控制参数或第一控制参数确定所述至少一条对消链路中所需开启的至少部分对消链路，通过所述第二控制参数或第一控制参数控制所述至少部分对消链路将所述参考信号的幅度调整至与接收的通信信号中的干扰信号的幅度相同、并且控制至少部分对消链路将所述参考信号的相位调整至与所述接收的通信信号中的干扰信号的相位相反，得到所述第一对消信号或第二对消信号。
进一步地，主控部件，或者可以称为反馈控制件(如图6中所示)，将所述第一对消信号或所述第二对消信号在接收端与接收信号进行对消处理；通过接收端采集至少一个采集点的功率或/和相位，基于采集到的信号功率或/和相位选择对消处理后的信号对应的至少一条反馈链路，以得到调整后的第一对消信号或第二对消信号。
可见，通过采用上述方案，就能够在训练之后基于得到的控制参数，在通信阶段进行干扰消除，并且在其基础上，增加校准阶段以优化提升通信的性能、保证趋近最优消除效果。
另外，本实施例提供的方案，还可以采用消除电路产生抵消信号叠加的方法消除终端设备中的互调自干扰，以及采用两条抵消链路的架构优化分离模块的性能，减小参考信号收到的损耗。其中，在对消链路还能够增加额外滤波器，应对互调干扰模块周围可能存在的其它残留互调干扰信号。因此，本实施例提供的方案尤其适用于在5G双链接结构下，终端设备中的非线性器件会产生互调干扰信号，对接收端造成自干扰，自干扰信号功率在底噪以上40dB左右，影响通信系统正常工作的情况，终端设备中使用本方案后，可以在一定程度上消除互调干扰的影响。与原有的互调干扰抑制架构相比，本实施例提供的方案能够通过校准阶段而自适应调节对消信号，实时保持最佳自干扰抑制，可适应复杂多变的移动设备环境。此外，本装置不用针对某种器件做单独优化，以及工作在接收端前，可以与之前的多种设置在发射端的消除方法并存，进一步提升消除效果。
