其中,第一滤波器 6021通带包括目标频段 fl ,第二滤波器 6022通带包括 目标频段 f2, 且第一滤波器 6021阻带包括目标频段 f2, 第二滤波器 6022阻 带包括目标频段 fl , 即第一滤波器 6021与第二滤波器 6022在目标频段 fl以 及 f2上互斥。
本实施例中,第一滤波器 6021对目标频段 f2上的信号的抑制可以在 40dB 以上, 第二滤波器 6022对目标频段 fl上的信号的抑制也可以在 40dB以上。
需要说明的是, 上述给出的抑制为 40dB, 仅为本实施例中的一个例子, 可以理解的是, 在实际应用中, 除了是 40dB之外, 还可以是其他的数值, 例 如 30dB或 50dB, 只要使得第一滤波器 6021与第二滤波器 6022在目标频段 fl以及 f2上互斥满足系统需求, 具体数值此处不作限定。
调整后信号 B11被输入第一滤波器 6021 , 且调整后信号 B12被输入第二 滤波器 6022之后, 第一滤波器 6021以及第二滤波器 6022对 B11和 B12进行 合成滤波得到合成信号 Bll+B12。
上述描述的是天馈系统对第一天线振子上的信号所执行的处理流程, 同 理,天馈系统也会对第二天线振子以及第三天线振子上的信号执行类似的处理 流程, 从而得到合成信号 B21+B22, 以及合成信号 B31+B32。
( 6 )天馈系统通过各天线振子发射与该天线振子对应的合成信号。
当上述 3个天线振子上的合成信号均得到确认之后,则天馈系统可以通过 第一天线振子发射合成信号 B11+B12 , 通过第二天线振子发射合成信号 B21+B22, 通过第三天线振子发射合成信号 B31+B32。
本发明实施例中, 天线振子的覆盖频段包含目标频段, 所以天馈系统可以 通过天线振子接收到多频段信号,之后可以通过滤波器将该多频段信号分离成 独立的 N个频段的信号并分别进行相位和 /或幅度调整, 最后再将调整后的信 号进行合并输出, 由上可知, 本发明实施例中, 只需要使用一个天馈系统即可 实现不同频段信号独立调整幅度和 /或相位, 因此能够筒化天馈系统安装过程, 降低多频段通信时天馈系统的安装复杂度, 从而推动多频段通信的发展。
可以理解的是,本发明实施例中的分离滤波器和合成滤波器可以为同一器 件, 只是分离滤波器的输入端、 输出端与合成滤波器的输入端、 输出端正好相 反,分离滤波器所执行的操作可以看作是将信号反向输入合成滤波器时合成滤 波器所执行的操作。
本发明实施例中所涉及的调整器可以是独立的器件,也可以是具备多路调 整功能的器件中的一路, 所涉及的第一滤波器、 第二滤波器、 第三滤波器或第 四滤波器均可以是独立的器件, 也可以是集成有多路滤波功能的器件中的一 路。
本发明实施例还提供一种基站系统,其包括上述实施例中提供的任意一种 天馈系统, 并进一步提供一种包括该基站系统的通信系统。
本发明实施例所提供的天馈系统, 不仅适用于无线通信系统,还适用于雷 达、 微波传输等其他通信领域。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分步骤 是可以通过程序来指令相关的硬件完成,该程序可以存储于一种计算机可读存 储介质中, 上述提到的存储介质可以是只读存储器, 磁盘或光盘等。
以上对本发明所提供的一种信号发送方法、信号接收方法、天馈系统以及 基站系统进行了详细介绍,对于本领域的一般技术人员,依据本发明实施例的 思想, 在具体实施方式及应用范围上均会有改变之处, 因此, 本说明书内容不 应理解为对本发明的限制。
