下面，将参照附图详细描述根据本公开的各个实施例。需要注意的是，在附图中，将相同的附图标记赋予基本上具有相同或类似结构和功能的组成部分，并且将省略关于它们的重复描述。
相关技术中有一种信号接收方法，在该方法中，获取相控阵天线的最大扫描角度范围，之后，每次按照预设的扫描角度控制相控液晶阵天线在最大扫描角度范围内进行顺序扫描，以接收信号。
上述信号接收方法采用的是顺序扫描的方式，接收信号所使用的时间较长，接收信号的效率较低。
本公开实施例提供了一种信号接收方法，例如用于比如显示装置的电子设备中的处理组件，该处理组件可以为处理器或处理芯片。该显示装置可以为智能手机、平板电脑或智能电视等。如图1所示，该方法包括：
步骤101、获取相控阵天线的最大扫描角度范围。
步骤102、基于相控阵天线接收到的信号的功率，采用二分查找法缩小最大扫描角度范围，直至缩小后的扫描角度范围的最大值和最小值的差值小于预设值，缩小后的扫描角度范围用于接收信号。
当缩小后的扫描角度范围的最大值和最小值的差值小于预设值时，显示装置可以通过相控阵天线基于缩小后的扫描角度范围来接收信号。
在一些实施例中，上述的预设值可以是该相控阵天线的最小角度扫描间隔。
在一些实施例中，该方法还包括将相控阵天线的主瓣对准缩小后的扫描角度范围的最大值和最小值之一的方向以接收信号。
综上所述，本公开的至少一些实施例提供的一种信号接收方法，能够获取相控阵天线的最大扫描角度范围，并基于相控阵天线接收到的信号的功率，采用二分查找法缩小最大扫描角度范围，直至缩小后的扫描角度范围的最大值和最小值的差值小于预设值。由于采用二分查找法对最大扫描角度范围进行了多次缩小，因而缩短了比如显示装置的电子装置接收信号所使用的时间，提高了接收信号的效率。
本公开的至少一些实施例提供了一种信号接收方法，例如用于显示装置中的处理组件，如图2所示，该方法包括如下的步骤201到步骤203：
步骤201、获取相控阵天线的最大扫描角度范围。
示例的，相控阵天线的最大扫描角度范围可以为-60°～+60°，示例的，如图3所示。例如，相控阵天线的最大扫描角度范围可以预存至该相控阵天线包括或相关联的存储器中，由此通过读取该存储器可以获取该相控阵天线的最大扫描角度范围。再例如，相控阵天线的最大扫描角度范围可以是预先设置的，或者是在上述的处理组件与相控阵天线建立连接时根据从相控阵天线传输的信号确定出的，其中从相控阵天线传输的信号可包括相控阵天线的类型、型号等信息或直接包括最大扫描角度范围的信息。然而，应理解，本公开的实施例对此不作限制。
在本公开实施例中，相控阵天线可以为相控阵液晶天线。相控阵天线还可以为基于微机电系统(Micro-Electro-Mechanical System，MEMS)的开关型移相器的相控阵天线、PIN二极管开关型移相器的相控阵天线、互补金属氧化物半导体(Complementary Metal Oxide Semiconductor，CMOS)开关型移相器的相控阵天线、基于变容二极管反射型移相器的相控阵天线或基于铁电体等磁导率可调介质的加载线型移相器的相控阵天线等，本公开实施例对 相控阵天线的类型不做限定。
步骤202、将最大扫描角度范围对应的角确定为待处理角。
参见图3，在本步骤中，可以将最大扫描角度范围对应的角θ确定为待处理角。
步骤203、执行角度范围缩小过程。
如图4所示，步骤203的一个示例可以包括如下的步骤(子步骤)2031到2036：
步骤2031、检测待处理角的角度是否小于预设值。当待处理角的角度小于预设值时，执行步骤2032，当待处理角的角度不小于预设值时，执行步骤2033。
示例的，预设值可以为0.1°。参见图3，待处理角θ的角度为120°，由于120°>0.1°，也即是，待处理角的角度不小于预设值，那么执行步骤2033。
步骤2032、将待处理角对应的角度范围确定为缩小后的扫描角度范围。
当待处理角的角度小于预设值时，将待处理角对应的角度范围确定为缩小后的扫描角度范围，至此，最大扫描角度范围的缩小流程结束，之后，显示装置可以通过相控阵天线基于确定的缩小后的扫描角度范围来接收信号。
步骤2033、按照待处理角的角平分线，将待处理角划分为对称的两个角。执行步骤2034。
在本公开的一些实施例中，假设要接收的信号的位置位于图3中的59.96°的位置处，参见图3，待处理角θ的角度不小于预设值，那么按照待处理角θ的角平分线x1，将待处理角θ划分为对称的两个角，这两个角分别为θ1和θ2。其中，θ1对应的角度范围为(-60°，0°)，θ2对应的角度范围为(0°，60°)。
步骤2034、控制相控阵天线的主瓣方向分别指向两个角的角平分线的方向。执行步骤2035。
参见图3，在本步骤中，处理组件可以控制相控阵天线的主瓣方向分别指向两个角(即θ1和θ2)的角平分线的方向，θ1的角平分线的方向如图3中k1所指示的方向(即-30°所指示的方向)，θ2的角平分线的方向如图 3中k2所指示的方向(即30°所指示的方向)。
步骤2035、获取相控阵天线在两个角的角平分线的方向接收到的信号的功率。执行步骤2036。
参见图3，处理组件获取相控阵天线在θ1的角平分线的方向k1接收到的信号的功率P1，以及相控阵天线在θ2的角平分线的方向k2接收到的信号的功率P2。
步骤2036、在两个角中选择对应的接收到的信号功率较大的角作为新的待处理角，再次执行步骤203。
参见图3，相控阵天线在方向k2接收到的信号功率P2大于相控阵天线在方向k1接收到的信号功率P1，那么处理组件将θ2作为新的待处理角。
之后，再次执行步骤203，参见图5，θ2的角度为60°，其不小于0.1°，那么处理组件按照θ2的角平分线x2，将θ2划分为对称的两个角，这两个角分别为θ21和θ22。其中θ21对应的角度范围为(0°，30°)，θ22对应的角度范围为(30°，60°)，处理组件控制相控阵天线的主瓣方向分别指向两个角(即θ21和θ22)的角平分线的方向，θ21的角平分线的方向如图5中k21所指示的方向(即15°所指示的方向)，θ22的角平分线的方向如图5中k22所指示的方向(即45°所指示的方向)，之后，处理组件获取相控阵天线在θ21的角平分线的方向k21接收到的信号的功率P21，以及相控阵天线在θ22的角平分线的方向k22接收到的信号的功率P22。相控阵天线在方向k22接收到的信号功率P22大于相控阵天线在方向k21接收到的信号功率P21，那么将θ22作为新的待处理角。
再次执行步骤203，参见图6，θ22的角度为30°，其不小于0.1°，那么处理组件按照θ22的角平分线x3，将θ22划分为对称的两个角，这两个角分别为θ31和θ32。其中θ31对应的角度范围为(30°，45°)，θ32对应的角度范围为(45°，60°)，处理组件控制相控阵天线的主瓣方向分别指向两个角(即θ31和θ32)的角平分线的方向，θ31的角平分线的方向如图6中k31所指示的方向(即37.5°所指示的方向)，θ32的角平分线的方向如图6中k32所指示的方向(即52.5°所指示的方向)，之后，处理组件获取相控阵天线在θ31的角平分线的方向k31接收到的信号的功率 P31，以及相控阵天线在θ32的角平分线的方向k32接收到的信号的功率P32。相控阵天线在方向k32接收到的信号功率P32大于相控阵天线在方向k31方向接收到的信号功率P31，那么将θ32作为新的待处理角。
再次执行步骤203，θ32的角度为15°，其不小于0.1°，那么处理组件按照θ32的角平分线x4，将θ32划分为对称的两个角，这两个角分别为θ41和θ42。其中θ41对应的角度范围为(45°，52.5°)，θ42对应的角度范围为(52.5°，60°)，处理组件控制相控阵天线的主瓣方向分别指向两个角(即θ41和θ42)的角平分线的方向，之后，处理组件获取相控阵天线在θ41的角平分线的方向k41(即48.75°所指示的方向)接收到的信号的功率P41，以及相控阵天线在θ42的角平分线的方向k42(即56.25°所指示的方向)接收到的信号的功率P42。相控阵天线在方向k42接收到的信号功率P42大于相控阵天线在方向k41接收到的信号功率P41，那么将θ42作为新的待处理角。
以此类推，在执行第11次角度范围缩小过程时，新的待处理角θ12的角度为0.12°，其不小于0.1°，那么处理组件按照θ12的角平分线x11，将θ12划分为对称的两个角，这两个角分别为θ12和θ13。其中θ12对应的角度范围为(59.88°，59.94°)，θ13对应的角度范围为(59.94°，60°)，处理组件控制相控阵天线的主瓣方向分别指向两个角(即θ12和θ13)的角平分线的方向，之后，处理组件获取相控阵天线在θ12的角平分线的方向k12(即59.91所指示的方向)接收到的信号的功率P12，以及相控阵天线在θ13的角平分线的方向k13(即59.97°所指示的方向)接收到的信号的功率P13。相控阵天线在方向k13接收到的信号功率P13大于相控阵天线在方向k12接收到的信号功率P12，那么将θ13作为新的待处理角。
再次执行步骤203，将θ13的角度为0.06，其小于0.1，那么将θ13对应的角度范围(59.94°，60°)确定为缩小后的扫描角度范围，至此，最大扫描角度范围的缩小流程结束，之后，显示装置可以通过相控阵天线基于确定的缩小后的扫描角度范围来接收信号。
由以上内容可知，采用本公开实施例提供的信号接收方法，当要接收的信号的位置位于图3中的59.96°的位置处，那么处理组件最多执行11次角 度范围缩小过程便可以接收到信号，每执行一次角度范围缩小过程，相控阵天线执行两次信号扫描操作，也即是相控阵天线最多执行22次信号扫描操作，以使处理组件得到在两个角的角平分线的方向接收到的信号的功率。而采用相关技术中的顺序扫描方法，按照预设值0.1°扫描，需要扫描1201次才能接收到信号，接收信号所使用的时间较长，接收信号的效率较低。相较于相关技术，本公开实施例提供的信号接收方法，由于采用二分查找法对最大扫描角度范围进行了缩小，因而缩短了接收信号所使用的时间，提高了接收信号的效率。
在本公开实施例中，假设相控阵天线的最大扫描角度范围为-φ～+φ，预设值为β，那么采用本公开实施例提供的信号接收方法，通过二分查找法逐次逼近要接收的信号的位置，最多执行N1次信号扫描操作，其中，
Figure PCTCN2019079186-appb-000001
而采用相关技术中的顺序扫描的方式，共需要执行N2次信号扫描操作，其中，
Figure PCTCN2019079186-appb-000002
由以上可知，N1<<N2，可见，本公开实施例提供的信号接收方法极大缩短了接收信号所使用的时间，提高了接收信号的效率。
需要说明的是，本公开提供的信号接收方法，不仅可用于一维度信号扫描，还可用于多维度信号扫描。
需要说明的是，本公开实施例提供的信号接收方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行相应增减，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本公开的保护范围之内，因此不再赘述。
综上所述，本公开实施例提供的一种信号接收方法，能够获取相控阵天线的最大扫描角度范围，并基于相控阵天线接收到的信号的功率，采用二分查找法缩小最大扫描角度范围，直至缩小后的扫描角度范围的最大值和最小值的差值小于预设值。由于采用二分查找法对最大扫描角度范围进行了多次缩小，因而缩短了显示装置接收信号所使用的时间，提高了接收信号的效率。

描述于本申请实施例中所涉及到的单元或模块可以通过软件的方式实现，也可以通过硬件的方式来实现。所描述的单元或模块也可以设置在处理器中，例如，可以描述为：一种处理器包括获取模块以及缩小单元。这些单元或模块的名称在某种情况下并不构成对该单元或模块本身的限定。
本公开的至少一些实施例提供了一种计算机可读存储介质，该存储介质为非易失性可读存储介质，该计算机可读存储介质中存储有指令，当可读存储介质在处理组件上运行时，使得处理组件执行如图1或图2所示的信号接收方法。
本公开的至少一些实施例提供了一种计算机程序产品，该计算机程序产品中存储有指令，当其在计算机上运行时，使得计算机执行如图1或图2所示的信号接收方法。
本公开的至少一些实施例提供了一种芯片，该芯片包括可编程逻辑电路和/或程序指令，当芯片运行时用于实现如图1或图2所示的信号接收方法。
本公开的至少一些实施例还提供了一种电子设备，其包括如上述任一实施例所述的信号接收装置。该电子设备例如可以是个人电脑、智能手机、智能电视、平板电脑、个人数字助理、电子书阅读器等，本公开的实施例对此不作限制。如图9所示，根据本公开至少一些实施例的电子设备900包括如上述任一实施例所述的信号接收装置910。
有以下几点需要说明：
(1)本公开实施例附图只涉及到本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合以得到新的实施例。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，本公开的保护范围应以所述权利要求的保护范围为准。
