本申请涉及通信技术领域，特别是涉及一种天线及无线信号发送、接收方法。
背景技术
随着无线通讯技术的迅猛发展，人们对通讯系统的容量、传输速率等不断地提出更高的要求，一系列网络容量提升技术和架构被提出，如水平劈裂、垂直劈裂等等宏站演进技术，其中水平劈裂是指在水平面上增加波束数量，从而实现系统容量翻倍，而垂直劈裂则是指在垂直面上增加波束数量。
但从实现的角度来看，水平劈裂天线使用多列天线,所以天线宽度会增加，而垂直劈裂是通过电路网络实现，所以系统复杂度会提升。另外，由于水平劈裂和垂直劈裂改变了原有天线的扇区覆盖，所以需要重新对系统进行大量的网络规划和网络优化。
因此，基于宏站的演进技术普遍存在着天线体积增加大以及设备更加复杂的问题。

具体实施方式
为了使本技术领域的人员更好地理解本申请实施例中的技术方案，并使本申请实施例的上述目的、特征和优点能够更加明显易懂，下面结合附图对本申请实施例中技术方案作进一步详细的说明。
图1为本申请实施例提供一种天线的结构示意图。
如图1所示，该天线包括：第一功分器10、第二功分器20、信号复用网络30、复用天线阵列40、第一天线阵列50和第一移相网络60。
第一功分器10用于接收第一波束信号，并将第一波束信号分成k1+m个第一波束分路信号。根据发送的第一波束的要求，第一功分器10可以选择等功分器或不等功分器，并且不等功分器分得各个第一波束分路信号的大小，根据第一波束的要求不同而有差异。
第二功分器20用于接收第二波束信号，并将第二波束信号分成k2个第二波束分路信号。同样，根据发送的第二波束的要求，第二功分器20可以选择等功分器或不等功分器。
第一移相网络60对m个第一波束分路信号进行移相处理，得到M个第一波束分路移相信号，M个第一波束移相信号的相位都不相同。第一移相网络60包括至少M-1个移相位器62，或，M-1个移相位器和至少一个功分器组成，其中，当m＝M时，第一移相网络60可以为M个移相支路组成，并且至少M-1个移相支路上都设置有一个移相位器，这样对于m个第一波束分路信号进行移相后，可以保证得到的M个第一波束分路移相信号的相位都不相同。另外，当m＜M时，如图2所示，图中m＝3，M＝5，此时，第一移相网络60由移相位器和功分器进行级联，图中，62为移相位器，61为一分二功分器，同样，图2所示的第一移相网络也可以得到M个第一波束分路移相信号。
信号复用网络30的输入端有L个，L个输入端分为两部分，第一部分L1个输入端接收k1个第一波束分路信号，第二部分L2个输入端接收k2个第二波束分路信号。在本申请实施例中，L小于等于K，并且L1+L2的总个数小于等于L。上述设计，可以保证至少有k1个第一波束信号、k2个第二波束输入到信号复用网络中，并且第一波束分路信号和第二波束分路信号占用的输入端数量小于信号复用网络的输入端总数量。
信号复用网络30的作用是将k1个第一波束分路信号和k2个第二波束分路信号进行信号复用和移相处理，得到K个复用信号，每个复用信号内都包含有第一波束分路信号和第二波束分路信号，并且不同复用信号的相位不相同。
在本申请实施例中，如图3所示，信号复用网络30由多个移相位器31和一个3DB电桥组成的巴特勒矩阵32组成，在巴特勒矩阵32的每个输入端可以根据需要设置一个移相位器31或不设置移相位器，巴特勒矩阵32的每个输出端根据需要设置有1个移相位器31或不设置移相位器，另外，至少一个输出端上可以不设置移相位器。如图3所示巴特勒矩阵32为二进四出的网络，即k1＝k2＝L1＝L2＝1，K＝4，在本申请其它实施例中，巴特勒矩阵32还可以是一个多进多出的网络。
如图1所示，复用天线阵列40包括K个复用天线阵子，K个复用天线阵子呈直线排列，每个复用天线阵子分别与信号复用网络40的一个输出端相连接，将信号复用网络40输出的一个复用信号发射出去。
第一天线阵列50包括M个第一天线阵子，M个第一天线阵子与K个复用天线位于一条直线上，并且M个第一天线阵子位于K个复用天线阵子的一端。每个第一天线阵子分别与第一移相网络60中的一个输出端相连接，将第一移相网络60输出的一个第一波束分路移相信号发射出去。
复用天线阵列40发射的K个复用信号中的第二波束分路信号形成第二 波束，复用天线阵列40发射的K个复用信号的第一波束分路信号和第一天线阵列60发射的M个第一波束分路移相信号共同形成第一波束，并且发射形成的第一波束和第二波束的发射方向不同。
另外，根据天线的互异性，本申请实施例提供的该天线还可以接收波束，在接收目标波束时，复用天线阵列40中的K个复用天线阵子还可以接收目标波束，信号复用网络30对接收到的目标波束进行分路移相后得到k1个第三波束分路信号和k2个第四波束分路信号。第一天线阵列50接收目标波束，M个第一天线阵子将接收到的目标波束移相后得到m个第三波束分路信号。第一功分器10将k1+m个第三波束分路信号合到一起形成第三波束信号；第二功分器20将k2个第四波束分路信号合到一起形成第四波束信号。
本申请实施例提供的该天线，根据发射的第一波束和第二波束的要求，首先将第一波束分成k1+m个第一波束分路信号，并且将第二波束分别分成k2个第二波束分路信号，然后利用第一移相网络对k1第一波束分路信号进行移相，利用信号复用网络对k1第一波束分路信号和k2个第二波束分路信号进行信号复用、移相处理，得到K个复用信号，将M个第一波束分路移相信号通过第一天线阵列50发射，将将K个复用信号由复用天线阵列40发射，发射后K个复用信号形成第二波束，K个复用信号和M个第一波束分路移相信号共同形成第一波束。通过控制对第一功分器和第二功分器分的的分路信号的大小以及控制对各分路信号以及复用信号进行移相的相位大小，可以使得最终得到的第一波束和第二波束的增益、下倾角以及垂直面波束宽度都可以不相同。
由此可见，本申请实施例提供的该天线，可以使得两个不同的波束复用部分天线阵子，并且通过调节波束信号的分路信号大小以及相位，可以形成的两个波束的下倾角不同，使得两个波束指向不同，进而覆盖区域不 同且不重叠。因此，该天线可以在天线体积不增加的情况下，实现系统容量增加。
同时，该方案只需设置第一功分器和第二功分器的分路信号大小，以及控制第一移相网络和信号复用网络对分路信号移相相位大小即可，实现方便简单，系统复杂度低。
图4为本申请实施例提供另一种天线的结构示意图。
在上一个实施例中，将第一天下阵列和复用天线阵列作为整体来看，仅仅将天线阵列的部分天线阵子进行复用，并且发射第二波束的全部天线阵子与发射第一波束的部分天线阵子复用，在本申请实施例中，还可以将发射第二波束的部分天线阵子与发射第一波的部分天线阵子进行复用，形成一种新的复用方案。如图4所示，该天线可以还可以包括：第二天线阵列90和第二移相网络100。
在本申请实施中，第二功分器20将第二波束信号分成k2+n个第二波束分路信号。另外，k2个第二波束分路信号的大小和n个第二波束分路信号的大小可以根据第二波束的要求而设定。
第二移相网络100对n个第二波束分路信号进行移相处理，得到N个第二波束分路移相信号，N个第二波束移相信号的相位都不相同，n小于等于N,并且N小于M。即从整体来看，形成第二波束的天线阵子的数量小于形成第一波束的天线阵子的数量。
在本申请实施例中，当n等于N时，第二移相网络可以由至少N-1个移相位器组，当n小于N时，所述第二移相网络可以由至少N-1个移相位器和至少一个功分器级联组成，详细描述可以参考上述关于第一移相网络60的描述，在此不再赘述。
第二天线阵列90包括N个第二天线阵子，N个第二天线阵子与第一天 线阵子、复用天线阵子位于一条直线上，并且第一天线阵列50和第二天线阵列100分别位于复用天线阵列40的两端。第二天线阵列90用于将移相后的N个第二波束分路移相信号发射出去。
在本申请实施例中，通过控制对第一功分器和第二功分器分的的分路信号的大小以及控制对各分路信号以及复用信号进行移相的相位大小，可以使得最终得到的第一波束和第二波束的增益、下倾角以及垂直面波束宽度都可以不相同。，进而覆盖区域不同且不重叠。因此，该天线可以在天线体积不增加的情况下，实现系统容量增加。
同时，该方案只需设置第一功分器和第二功分器的分路信号大小，以及第一移相网络、第二移相网络和信号复用网络对分路信号移相相位大小即可，实现方便简单，系统复杂度低。
图5为本申请实施例提供的一个应用实施例中天线的结构示意图。如图5所示，该天线包含有天线模块16、两个信号复用网络、四个功分器、两个第一移相网络、两个第二功分器、两个第二移相网络、两个第一射频收发单元以及两个第二射频收发单元，其中：天线模块采用双极化阵子且按照单列均匀排列的天线阵列，每个阵子之间的间距为108mm，天线阵列中包含有2个复用天线阵子、10个第一天线阵子和2个第二天线阵子，两个信号复用网络分别为主极化信号复用网络1和交叉极化信号复用网络2，两个第一移相网络分别为第一主极化移相网络5和第一交叉极化移相网络6，两个第一功分器3和4，两个第二功分器7和8，两个第二移相网络分别为第二主极化移相网络9和第二交叉极化移相网络11，两个第一射频收发单元分别为12和13，两个第二射频收发单元分别为14和15。
在本申请实施例中，第一功分器3和4都为一分七不等功分器，第二功分器7和8都为一分三不等分功分器。
主极化信号复用网络1和交叉极化信号复用网络2都由一个3DB电桥 和两个移相位器组成。
第一主极化移相网络5和第一交叉极化移相网络6的结构相似，都由两层10个移相位器、1层一分二等功分器级联组成，从而具有使得第一波束具有下倾角0～12度可调特性。当第一波束的下倾角为9度时，1-12天线阵子的幅度相位特性如表1所示，表中阵子是指天线阵子，第一波束分路信号是指天线阵子上发射的第一波束分路信号。

第二主极化移相网络9和第二交叉极化移相网络11的结构相似，都由两个移相位器组成，从而具有使得第二波束具有下倾角22度的特性。11-14天线阵子的幅度相位特性如表2所示，表中阵子是指天线阵子，第二波束分路信号是指天线阵子上发射的第二波束分路信号。

两个第一射频收发单元12和13的发射功率均为45dBm，两个第二射 频收发单元14和15的发射功率均为39dBm。
图6为现有的AAS方案对应的劈裂波束方向图。图7为现有AAS方案对应的覆盖效果图。
AAS(Active Antenna System，有源天线系统)方案通过在天线垂直维度留出更多的端口，以增加垂直维度的处理能力。
图8为本申请实施例图5提供的天线测试的波束对比图。图9为本申请实施例图5提供天线测试的覆盖效果图。
图7所示的两条曲线，表示随距离变化的接收信号强度，曲线越接近表示两个波束之间的干扰越大，SINR越低从而吞吐量越低。从图8中可见，与图7现有方案的距离与接收信号强度曲线相比，本申请实施例提供的方案在距离天线0～100米的近端区域，第一波束与第二波束之间的信号强度差异显著大于现有方案，故该区域SINR提升，系统容量也随之提升。另外，在距离天线150～500米的远端区域，第一波束与第二波束之间的信号强度差异也显著大于现有方案，故该区域SINR提升，系统容量也随之提升。
可以理解的是，本申请可用于众多通用或专用的计算系统环境或配置中。例如：个人计算机、服务器计算机、手持设备或便携式设备、平板型设备、多处理器系统、基于微处理器的系统、置顶盒、可编程的消费电子设备、网络PC、小型计算机、大型计算机、包括以上任何系统或设备的分布式计算环境等等。

需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
基于上述图1提供的天线，本申请实施例还提供了一种天线信号发送方法，如图10所示，该方法可以包括：
