在介绍本申请实施例之前，首先对无线空口的相关知识进行介绍说明。
目前，在无线局域网中，无线空口是指无线访问接入点(access point，AP)和站点(Station，STA)上的虚拟逻辑口，其中，AP可以为通信服务器、路由器、交换机、 网桥、计算机等，STA可以为手机、平板电脑、超级移动个人计算机(Ultra-mobile Personal Computer，UMPC)、上网本、可穿戴设备(比如，智能手环和智能手表等)以及车载设备等设备。AP和STA可以通过无线空口和无线空口之间的无线链路进行通信，且不同的STA的通信频率不同。随着通信需求的日益增长，无线空口的利用率越来越高，使得无线空口的频率资源越来越紧张，比如，无线空口从KHZ、MHZ到GHZ等不同的通信频率都有对应的STA进行通信。在同一时间且不同通信频率下通信的STA越多，导致相邻STA之间的干扰问题越严重，从而影响STA对于信号的接收。因此，需要一种方法来降低STA之间的干扰。
目前，通常利用接收机中的滤波器降低STA之间的干扰。图1为一种接收机的结构示意图，该接收机包括：依次连接的天线、滤波器和接收电路，天线用于接收电磁波，并通过传输线缆将接收到的电磁波传输给滤波器；滤波器用于对电磁波中特定频率或者特定频率以外的频率进行滤除，以得到一个特定频率的电磁波或者消除一个特定频率的电磁波；接收电路用于接收滤波后的电磁波，并对滤波后的电磁波进行信号的放大和转换。图1中仅示出了该接收机的部分结构。
其中，图1中所示的滤波器可以包括声表滤波器(saw filter)、陶瓷滤波器(ltcc fiter)和分立滤波器(discrete lc filter)。图2为一种分立滤波器的结构示意图，该分立滤波器包括：输入端、第一电容C1、第二电容C2、电感L和输出端，第一电容C1的一极、电感L的一端与输入端耦合于第一节点P1，电感L的另一端、第二电容C2的一极与输出端耦合于第二节点P2，第一电容C1的另一极和第二电容C2的另一极均与接地端耦合。分立滤波器在工作过程中，电感L阻止高频信号通过而允许低频信号通过，第一电容C1和第二电容C2允许高频信号通过而阻止低频信号通过。对于需要截止的高频信号，利用第一电容C1和第二电容C2进行吸收，利用电感L进行阻碍；对于需要放行的低频信号，利用第一电容C1和第二电容C2的高阻抗特性、以及电感L的低阻抗特性使其通过。
但是，图1所示的接收机中的滤波器会增大接收机的面积，将接收机应用于电子设备中时，增大了电子设备的面积；另一方面，滤波器自身的插入损耗会消耗电磁波中的能量，从而降低接收机的灵敏度。
基于此，本申请实施例提供一种接收机及电子设备，该接收机包括：至少一个接收通道，该至少一个接收通道包括第一接收通道，该第一接收通道包括相互耦合的第一电感和第一接收电路；该第一电感，用于对第一频段的接收信号进行滤波，得到第一接收信号，其中，该第一电感的自谐振频率在该第一频段对应的干扰频段内；该第一接收电路，用于对该第一接收信号进行处理。本申请实施例提供的接收机通过该第一接收通道中的第一电感对第一频段的接收信号进行滤波，由于第一电感的自谐振频率在第一频段对应的干扰频段内，利用第一电感的自谐振原理，可以阻止该干扰频段的信号通过，从而实现对该第一频段的接收信号的滤波功能，与通常利用滤波器实现滤波功能的接收机相比，本技术方案提供的接收机在实现滤波功能的同时，减小了接收机的面积；进一步的，将接收机应用在电子设备中时，减小了电子设备的面积。

本领域技术人员可以理解，图3中示出的手机结构并不构成对手机的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
图4为本申请实施例提供的一种接收机的结构示意图，该接收机包括：至少一个接收通道，该至少一个接收通道包括第一接收通道，所述第一接收通道包括相互耦合的第一电感和第一接收电路；该第一电感，用于对第一频段的接收信号进行滤波，得到第一接收信号，其中，该第一电感的自谐振频率在该第一频段对应的干扰频段内；该第一接收电路，用于对该第一接收信号进行处理。图4中仅示出了接收机的部分结构。
其中，该至少一个接收通道可以包括一个接收通道，也可以包括多个接收通道。比如，当该至少一个接收通道包括一个接收通道时，该接收通道为第一接收通道。当该至少一个接收通道包括多个接收通道时，该至少一个接收通道可以包括两个接收通道、三个接收通道，甚至更多的接收通道，具体可以根据实际需求或者相关技术人员的经验而定，本申请对此不做具体的限定。
另外，该第一频段可以为低频段、中频段和高频段中的任意一个频段。其中，该低频段、该中频段和该高频段是按照该接收信号的频率从小到大的顺序划分得到的。在第一种可能的示例中，该第一频段可以为低频段，此时该第一频段的频率范围可以为500～1000兆赫(MHZ)；在第二种可能的示例中，该第一频段也可以为中频段，此时该第一频段的频率范围可以为1000～2300兆赫(MHZ)；在第三种可能的示例中，该第一频段也可以为高频段，此时该第一频段的频率范围可以为2300～2700兆赫(MHZ)。在实际应用中，该低频段、该中频段和该高频段中任意一个频段的频率范围可以比上述示例中所提供的频率范围更大或者更小，上述示例中所示出的频率范围仅仅是一种示例，比如，在实际应用中，该中频段的范围可以为1800～2300兆赫(MHZ)。具体可以根据实际需求或者相关技术人员的经验进行划分，本申请实施例对此不作具体限制。其中，该接收信号可以包括射频信号。
再者，第一电感的自谐振频率为第一电感的品质因数为零时，该电感的频率。该第一频段对应的干扰频段的中心频率大于或者等于该第一频段中心频率的2倍。比如，当第一频段中心频率为1250时，该第一频段对应的干扰频段的中心频率可以为大于或者等于2500。
其次，该第一电感的电感值与该第一频段的频率范围有关，即该第一频段的频率范围越大，该第一电感的电感值越小。下面分别将该第一频段包括不同的频率范围时，该第一电感的电感值与该第一频段的频率范围的关系进行说明。
在第一种可能的示例中，该第一频段可以为低频段，此时第一电感的电感值可以为33纳亨(nh)。在第二种可能的示例中，该第一频段可以为中频段，此时第一电感的电感值可以为16纳亨(nh)。在第三种可能的示例中，该第一频段可以为高频段，此时第一电感的电感值可以为8纳亨(nh)。在实际应用中，第一电感的电感值可以比上述示例中所提供的电感值更大或者更小，上述示例中所示出的电感值仅仅是一种示例，具体可以根据实际需求或者相关技术人员的经验进行划分，本申请实施例对此不作具体限制。
进一步的，该第一电感包括：叠层设置的线圈、以及设置在该线圈两端的金属电极。由于绕制该线圈的导线并不是理想的导线，存在导线损耗的等效电阻，第一电感的磁芯存在一定的热损耗，存在磁芯损耗的等效电阻，第一电感内部的导体(比如，线圈与线圈)之间存在着分布电容，存在线圈之间的等效电容，因此，该第一电感的等效模型包括等效电阻、等效电容和电感。
图5为本申请实施例提供的一种电感的等效模型示意图，由图5可知，该电感包括：第一电阻Rp、第二电阻Rs、电容C和电感L。其中，第一电阻Rp的一端、第二电阻Rs的一端和电容C的一极耦合于第一节点P1，第一电阻Rp的另一端与电感的一端耦合，第二电阻Rs的另一端、电感L的另一端和电容C的另一极耦合于第二节点P2。其中，第一电阻Rp为电感的磁芯损耗的等效电阻，第二电阻Rs为电感的线圈的导线损耗的等效电阻，电容C为电感线圈之间的等效电容，电感L为电感的实际感值。由于电容C的存在，使得电容C和电感L组成了一个谐振电路，该谐振电路的谐振频率为该电感的自谐振频率。
自谐振频率原理：当电感的频率低于自谐振频率时，电感的阻抗随着频率的增加 而增大；当电感的频率等于自谐振频率时，电感的阻抗达到最大值；当电感的频率高于自谐振频率时，电感的阻抗随着频率的增加而减小，当电阻下降到和电容形成一个谐振腔时，此时电感的品质因数Q为零呈现容性，电感呈现陷波器的特性，阻止此频率的信号通过。
图6为本申请实施例提供的一种电感的电阻值和感抗值与频率的变化趋势示意图，图6中的(a)为电感的电阻值与频率的变化趋势示意图，图6中的(b)为电感的感抗值与频率的变化趋势示意图。如图6中的(a)所示，横坐标为频率/兆赫(MHZ)，纵坐标为电阻值/欧姆(ohm)。由曲线S1可知，在自谐振频率前电阻值随频率的升高而增大，在自谐振频率处电阻值达到最大值，在自谐振频率后电阻值随频率的升高而减小；如图6中的(b)所示，横坐标为频率/兆赫(MHZ)，纵坐标为感抗值/纳亨(nh)。由曲线S2可知，在自谐振频率前感抗值随频率的升高而增大，在自谐振频率处感抗值达到最大值，在自谐振频率后感抗值可以近似为零。图6中以自谐振频率为2500MHZ为例。
电感的频率在变化的过程中，电感的品质因数随着频率的变化而变化。图7为本申请实施例提供的一种电感的品质因数与频率的变化趋势示意图，其中，横坐标为频率/兆赫(MHZ)，纵坐标为品质因数。由曲线S1可知，当频率在900MHZ之前，品质因数随频率的增加而增大，当频率增加到900MHZ时，品质因数达到最大值18，此时对信号的能量损失最小，因此电感的通带频率可以为900MHZ，当频率大于900MHZ靠近自谐振频率时，品质因数随频率的增加而减小，当频率等于2500率时，品质因数减小为0，当频率大于2500时，品质因数Q为会逐渐增大，但是增大后的品质因数Q任然较小可以近似为零，因此电感的阻带频率为2500MHZ。由图7可知，当电感的频率接近自谐振频率时，电感的品质因素Q随着频率的增加而迅速减小，当该电感的频率与该自谐振频率的差值的绝对值小于预设频率阈值时，该电感的品质因数小于或等于预设阈值，比如，在实际应用中，该预设频率阈值可以为50MHZ，该预设阈值可以等于5，此时该品质因数Q可以近似为零，此时该电感呈容性，此时电感具有窄带陷波滤波器(notch filter)的特性，阻止该频率以及距离该频率一定范围内的频率的信号通过，比如，该范围可以为±50MHZ，对该频率以及距离该频率一定范围内的频率的信号均具有滤波的作用，比如，电感对24500MHZ以及2550的信号均具有滤波的作用。图7中以自谐振频率为2500MHZ为例。
当该电感的频率与该自谐振频率的差值小于或等于预设频率阈值时，该电感的品质因数小于或等于预设阈值，比如，在实际应用中，该预设阈值等于5。此时电感呈现容性，该频率的接收信号可以被迅速衰减，已达到阻止此频率的信号通过效果，从而达到滤波的目的。下面基于自谐振频率原理将第一电感的滤波原理进行详细说明。
接收机接收第一频段的接收信号，该第一频段对应第一干扰频段，可以根据第一频段的频率范围确定该第一频段对应的第一干扰频段的频率范围，该第一干扰频段的频率范围为第一频段的频率范围的2倍。比如，第一频段的频率范围为500～1000兆赫(MHZ)时，该第一频段对应的第一干扰频段的频率范围为1000～2000兆赫(MHZ)，根据第一干扰频段的频率范围选择合适的第一电感进行滤波。具体的，该第一电感的自谐振频率在该第一干扰频段的频率范围内，且该第一频段的频率上限与该自谐振频 率的差值小于或等于预设频率阈值，示例性的，以该预设频率阈值为100兆赫(MHZ)为例，则该自谐振频率为1100MHZ，当频率大于1000MHZ且小于1200MHZ时，随着频率的增加第一电感的感抗值迅速减小，电感对于品质因数小于等于5，可以近似为零，此时，该第一电感呈现容性，因此，大于1000MHZ且小于1200MHZ的频率的信号可以被迅速衰减，已达到阻止此范围的频率的信号通过效果，从而达到滤波的目的。
进一步的，该第一电感的自谐振频率与该线圈的圈数和/或该线圈与该金属电极之间的距离有关。因此，在制作该第一电感的过程中，可以通过改变该第一电感的线圈的圈数和/或该线圈与该金属电极之间的距离，得到满足要求的自谐振频率。具体的，可以增大或者减小该第一电感的线圈的圈数和/或增大或者减小线圈与该金属电极之间的距离，得到满足要求的自谐振频率。
进一步的，该第一电感的品质因数与该金属电极的面积有关。因此，在制作该第一电感的过程中，可以通过增加该第一电感的线圈两端的金属电极的面积，减小线圈中的等效电阻，以提高第一电感在第一频段的品质因数，减小接收信号的能量损耗，提高接收机的接收灵敏度。品质因数Q满足公式(1)：
其中，r是第一电感的等效电阻，即r为第一电感的磁芯损耗的等效电阻与线圈的导线损耗的等效电阻之和。其中，线圈两端的金属电极的面积越大，等效电阻r越小，由公式(1)可知，等效电阻r越小，品质因数Q越大，从而可以通过增加该第一电感的线圈两端的金属电极的面积，以提高第一电感在第一频段的品质因数，减小接收信号的能量损耗，提高接收机的接收灵敏度。
可选的，当该第一电感是陶瓷电感时，该第一电感还包括陶瓷介质体，该陶瓷介质体可用于固定该第一电感的线圈。在制作该第一电感的过程中，还可以通过改变该陶瓷介质体的成分来提高该第一电感的品质因素，以降低接收信号的能量损耗。比如，可以将该陶瓷介质体中三氧化二铝Al2O3的含量从93％增加到98.5％，以提高该陶瓷介质体的介电常数，从而提高该第一电感的品质因素。
进一步的，该至少一个接收通道还包括：与该至少一个接收通道耦合的切换开关；该切换开关用于切换选通该至少一个接收通道中的不同接收通道。
其中，当该至少一个接收通道包括一个接收通道时，该切换开关包括一个切换开关，该切换开关可用于切换选通该接收通道。当该至少一个接收通道包括多个接收通道时，该切换开关可以包括一个切换开关、也可以包括多个切换开关。在第一种可能的示例中，该切换开关包括一个切换开关，该一个切换开关，可用于根据接收信号的频率切换选通该多个接收通道中的不同接收通道。在第二种可能的示例中，该切换开关包括多个切换开关，该多个切换开关中的每个切换开关，可用于切换选通该多个接收通道中对应的接收通道。
进一步的，该接收机还包括：至少一个天线，该至少一个天线与该至少一个接收通道一一对应耦合。该至少一个天线中的每个天线可用于接收信号，该信号可以为上文中提供的接收信号，该接收信号可以为电磁波信号。

在另一种可能的实施例中，该至少一个接收通道还包括：第二接收通道，该第二接收通道包括第二电感和第二接收电路；该第二电感，用于对第二频段的接收信号进行滤波，得到第二接收信号，该第一频段与该第二频段不同；该第二接收电路，用于对该第二接收信号进行处理。
进一步的，当该第一频段大于该第二频段时，该第一电感的电感值小于该第二电感的电感值。由于该第一频段与该第二频段不同，该第一频段对应的第一干扰频段的频率范围与该第二频段对应的第二干扰频段的频率范围不同，该第一电感与该第二电感用于对不同频段的接收信号进行滤波，从而该第一电感的自谐振频率与该第二电感的自谐振频率不同。
图9为本申请实施例提供的另一种接收机的结构示意图，该接收机包括：第一接收通道、第二接收通道、以及分别与该第一接收通道和第二接收通道耦合的第一天线和第二天线、以及信号处理单元。该第一接收通道包括第一切换开关、第一电感和第一接收电路，该第二接收通道包括第二切换开关、第二电感和第二接收电路。图9中所示的接收机的各个部分的功能和作用与上述实施例中提供的接收机的各个部分的功能和作用类似，此处不再赘述。图9中，以该接收机包括两个接收通道，每个通道对应一个切换开关为例进行的说明。在实际应用中，在接收机可以包括三个甚至更多的接收通道，本申请对比不做具体的限定。
可选的，该接收机还可以包括接收匹配模块，该接收模块电路可用于匹配该接收机的至少一个天线与该至少一个接收通道，使得至少一个天线与该至少一个接收通道接通。

将本申请实施例提供的接收机进行性能测试，在测试过程中，对第一接收频段的接收信号，以100千赫兹(kHz)的频率间隔，强度为-15dBm的单音信号进行干扰扫描，接收机可以正常接收该第一频段内的接收信号，无法接收单音信号，达到了滤波的目的。另一方面，降低了接收信号的能量损耗，提高了接收机的接收灵敏度。
本申请实施例提供一种接收机，该接收机包括：至少一个接收通道，该至少一个接收通道包括第一接收通道，该第一接收通道包括相互耦合的第一电感和第一接收电路；该第一电感，用于对第一频段的接收信号进行滤波，得到第一接收信号；该第一接收电路，用于对该第一接收信号进行处理。本申请实施例提供的接收机通过第一电感对第一频段的接收信号进行滤波，得到第一接收信号，从而达到滤波的效果，与图1所示的接收机相比，第一电感的面积小于滤波器的面积，减小了接收机的面积，将接收机集成在电子设备中时，减小了电子设备的面积。
