一种接收装置、发射装置及信号处理方法 技术领域
本申请涉及无线通讯技术领域，尤其涉及一种接收装置、发射装置及信号处理方法，尤其适用于通信领域，例如座舱域。
背景技术
在无线射频领域，收发信机的重要性不言而喻。目前，常用的射频接收机结构主要有超外差接收机和零中频接收机。
以零中频接收机为例，零中频接收机因其突出的性能优势(例如，结构简单、低功耗、低成本)得到了广泛地应用。一般情况下，零中频接收机可以工作在低于6GHz的无线通信频谱。然而，当零中频接收机的通信频段扩展到毫米波段(例如，26GHz、28GHz、60GHz等)时，由于毫米波段上的通信频率非常高，当通过零中频接收机将其进行变频处理得到基带信号时，容易出现基带处理器进行滤波处理的方式不能满足抗干扰和噪声抑制的要求，这无疑降低了零中频收发信机的工作性能。
为了实现收发信机可以兼顾多个不同通信频段的工作性能，收发信机的结构往往过于复杂，且成本过高。因此，如何提出一种结构简单的收发信机来保证多个不同频段的工作性能是急需解决的技术问题。

在一个示例中，如图1b所示，至少两个第一射频信号处理模块11包含第二射频信号处理模块111和第三射频信号处理模块112。具体来说，第二射频信号处理模块111与至少一个第一开关电路12的第一端口连接，第三射频信号处理模块112与至少一个第一开关电路12的第二端口连接；其中，第二射频信号处理模块111，用于获取第一射频信号；第三射频信号处理模块112，用于获取第二射频信号；这里，第一射频信号和第二射频信号属于不同的频率范围。示例性地，第一射频信号属于第一范围，第二射频信号属于第二范围。在一个示例中，大于或等于第一阈值的为第一范围，小于第一阈值的为第二范围。在一个示例中，大于第一阈值的为第一范围，小于等于第一阈值的为第二范围。
在一个示例中，第一阈值可以为本申请所描述的接收装置10在出厂时设置好的某个具体数值；在一个示例中，第一阈值可以为在2G(the Second Generation)、3G(the 3rdGeneration)、4G(the 4th Generation)乃至5G(the 5thGeneration)的演进过程中，本领域技术人员通过不断试验而获得的经验值(例如，该经验值可以默认为无线射频领域中的标准值)。例如，第一阈值可以为2.4GHz。又例如，第一阈值可以为5.8GHz。进一步地，在实际应用中，第一阈值是可以调整的，在不同的应用场景下，第一阈值的取值可以不同。

下面对接收装置10中第一开关电路处于不同连接状态时的具体工作过程进行展开说明：
在一个示例中，当基带处理器15获知第二射频信号处理模块从第一天线(例如，第一天线为接收天线)获取到第一射频信号，基带处理器15将至少一个第一开关电路的第一端口设置为连接状态，此时，第二射频信号处理模块111，用于从第一天线获取第一射频信号，以及生成第一中频模拟信号；其中，第一中频模拟信号为对第一射频信号进行混频得到的；第一模拟信号处理模块13，用于根据第一中频模拟信号生成第一基带模拟信号；模数转换模块14，用于生成第一数字基带信号；基带处理器15，用于根据第一数字基带信号进行处理；第一本振信号处理模块17，用于生成第一本振信号；第二本振信号处理模块18，用于生成第二本振信号。
在一个示例中，当基带处理器15获知第三射频信号处理模块从第一天线(例如，第一天线为接收天线)获取到第二射频信号，基带处理器15将至少一个第一开关电路的第二端口设置为连接状态，此时，第三射频信号处理模块112，用于从第一天线获取第二射频信号，以及生成第一放大模拟信号；其中，第一放大模拟信号为对第二射频信号进行放大得到的；第一模拟信号处理模块13，用于根据第一放大模拟信号生成第一模拟基带信号；模数转换模块14，用于生成第一数字基带信号；基带处理器15，用于根据第一数字基带信号进行处理；第一本振信号处理模块17，用于生成第一本振信号；第二本振信号处理模块18，用于生成第二本振信号。
在一个示例中，接收装置10的具体结构可以如图1f所示，其中，
第二射频信号处理模块111可以包括第一低噪声放大器(Low Noise Amplifier，LNA)和第一下变频混频器。在实际应用中，第二射频信号处理模块111除了包括第一低噪声放大器和第一下变频混频器之外，还可以包括第一旁路电路。
第三射频信号处理模块112可以包括第二低噪声放大器。在实际应用中，第三射频信号处理模块112除了包括第二低噪声放大器之外，还可以包括第二旁路电路。
具体来说，旁路电路区别于主回路电路(例如，主回路为第二低噪声放大器组成的电路)，是指因功能需要时，可以切换到另一条回路上而不致于影响射频信号处理模块的正常工作。
第一模拟信号处理模块13可以包括第一放大器(Amplifier)和至少两路第一正交I/Q处理电路；其中，第一I路处理电路包括第二下变频混频器、第一可变增益放大器、第一低通滤波器(Low Pass Filte，LPF)和第二放大器；第一Q路处理电路包括第三下变频混频器、第二可变增益放大器、第二低通滤波器和第三放大器；在一个示例中，第一放大器 和至少两路第一正交I/Q处理电路可以为独立的结构；在一个示例中，第一放大器和至少两路第一正交I/Q处理电路可以封装在一起，本申请不作具体限定。
模数转换模块14可以包括至少两个模数转换器。示例性地，至少两个模数转换器可以包括第一模数转换器和第二模数转换器，其中，第一模数转换器与第一I路处理电路相连，第二模数转换器与第一Q路处理电路相连。
第一本振信号处理模块17可以包括第一锁相环路PLL1(Phase Locked Loop，PLL)和第一高频振荡器。
第二本振信号处理模块18可以包括第二锁相环路PLL2和第二高频振荡器。
在本申请实施例中，锁相环路的主要功能是让某一高频率的振荡器锁定在一个低频率的、比较稳定的低频时钟源上，使高频的振荡源的稳定性和低频的时钟源稳定性趋于一致。锁相环路的工作原理是：高频振荡源产生的信号经过分频得到和参考时钟源频率相同的信号，该信号和参考时钟信号的频率/相位进行比较，比较的结果作为一个误差控制信号再去控制高频振荡器的频率/相位。通过这样的反馈控制，使高频振荡器的振荡趋于稳定，输出稳定的高频频率信号。该锁相环路产生的信号分别3倍频和2分频后作为第一级和第二级本振。
在本申请实施中，低噪声放大器，是指噪声系数很低的放大器。具体来说，低噪声放大器可以用于对接收到的射频信号进行放大。
在本申请实施例中，第一低噪声放大器和第二低噪声放大器可以为结构和类型相同的放大器，其中，第一低噪声放大器工作在第一范围，第二低噪声放大器工作在第二范围。这里，第一范围和第二范围属于不同的频率范围。

基于图1f所示的接收装置10的硬件结构示意图，下面具体阐述接收装置10是如何处理射频信号的。在一个示例中，在至少一个第一开关电路12的第一端口处于连接状态的情况下，第二射频信号处理模块111从接收天线16获取第一射频信号(例如，第一射频信号属于第一范围)，将获取到的第一射频信号和第一本振信号进行混频后，得到第一中频模拟信号；然后，将第一中频模拟信号发送至第一模拟信号处理模块13和第二本振信号做正交 混频，生成两路正交的第一模拟基带信号；之后，将两路正交的第一模拟基带信号发送至模数转换模块14，得到两路正交的第一数字基带信号，从而基带处理器15可以对两路正交的第一数字基带信号进行处理。
具体来说，上述描述中“将获取到的第一射频信号和第一本振信号进行混频后，得到第一中频模拟信号”可以是指，将获取到的第一射频信号和第一本振信号相减后取绝对值，得到第一中频模拟信号。“将第一中频模拟信号发送至第一模拟信号处理模块13和第二本振信号做正交混频，生成两路正交的第一模拟基带信号”可以是指，将第一中频模拟信号和第二本振相减后取绝对值，从而可以得到两路正交的第一模拟基带信号。可以理解的是，在至少一个第一开关电路12的第一端口处于连接状态的情况下，接收装置10可以通过“二次变频”(下变频过程)的结构，实现第一射频信号的接收。这里，第一射频信号属于第一范围。例如，第一射频信号为高频信号。
在一个示例中，在至少一个第一开关电路12的第二端口处于连接状态的情况下，第三射频信号处理模块112从接收天线16获取第二射频信号(例如，第二射频信号属于第二范围)，将获取到的第二射频信号进行放大，得到第一放大模拟信号；然后，将第一放大模拟信号发送至第一模拟信号处理模块13和第二本振信号做正交混频，生成两路正交的第一模拟基带信号；之后，将两路正交的第一模拟基带信号发送至模数转换模块14，得到两路正交的第一数字基带信号，从而基带处理器15可以对两路正交的第一数字基带信号进行处理。
具体来说，上述描述中“将第一放大模拟信号发送至第一模拟信号处理模块13和第二本振信号做正交混频，生成两路正交的第一模拟基带信号”可以是指，将第一放大模拟信号和第二本振相减后取绝对值，从而可以得到两路正交的第一模拟基带信号。可以理解的是，在至少一个第一开关电路12的第二端口处于连接状态的情况下，接收装置10可以通过“一次变频”的结构(也即：零中频结构)，实现第二射频信号的接收。

为了便于更好的理解本申请，下面介绍几个本申请所描述的技术方案可以适用的应用场景为：
场景一：扩展频率支持，收发装置30可以支持3GHz-5.8GHz通信频段。
现有技术中，以基站中的4G收发装置(例如，收发信机)产品为例，它的工作频率分布在3GHz以下的通信频段(也即：不支持3GHz以上的通信频段)，后来引入了LAA(Licence Assisted Access)技术，以载波聚合或者双连接为基础，由授权载波辅助非授权载波接入，以实现LTE网络的数据业务承载的补充，即：采用5.8GHz非授权(unlicensed)频段辅助现有4G频段通信，扩展通信带宽。
本申请所描述的收发装置(接收装置10和发射装置20)可以支持3GHz-5.8GHz通信频段。在一个示例中，以接收装置10接收通信频率为5.8GHz的第一射频信号为例，在至少一个第一开关电路的第一端口处于连接状态的情况下，第二射频信号处理模块从第一天线处获取通信频率为5.8GHz的第一射频信号，将第一射频信号和第一本振信号进行混频后，得到第一中频模拟信号；然后，将第一中频模拟信号发送至第一模拟信号处理模块和第二本振信号做正交混频，生成两路正交的第一基带信号(例如，第一模拟基带信号)，从而可以实现通信频率为5.8GHz第一射频信号的接收。
在一个示例中，以接收装置10接收通信频率为小于等于3GHz的第二射频信号为例，在至少一个第一开关电路的第二端口处于连接状态的情况下，第三射频信号处理模块从第一天线处获取通信频率为小于等于3GHz的第二射频信号，将获取到的第二射频信号进行放大，得到第一放大模拟信号；然后，将第一放大模拟信号发送至第一模拟信号处理模块和第二本振信号做正交混频，生成两路正交的第一基带信号(例如，第一模拟基带信号)，从而可以实现通信频率为小于等于3GHz的第二射频信号的接收。
在一个示例中，以发射装置发射20发射通信频率为5.8GHz的第三射频信号为例，在至少一个第二开关电路的第一端口处于连接状态的情况下，两路正交的第二基带信号(例如，第二模拟基带信号)在第二模拟信号处理模块的处理下，得到第二中频模拟信号；第五射频信号处理模块获取第二中频模拟信号，将第二中频模拟信号和第一本振信号进行混频之后，得到通信频率为5.8GHz第三射频信号。之后，该第三射频信号通过第二天线发射出去，从而可以实现通信频率为5.8GHz第三射频信号的发射。
在一个示例中，以发射装置发射20发射通信频率为小于等于3GHz的第四射频信号为例，在至少一个第二开关电路的第二端口处于连接状态的情况下，两路正交的第二基带信号(例如，第二模拟基带信号)在第二模拟信号处理模块的处理下，得到第二中频模拟信号；第六射频信号处理模块获取第二中频模拟信号，将第二中频模拟信号进行射频功率放大之后，得到通信频率为小于等于3GHz的第四射频信号。之后，该第四射频信号通过第二天线发射出去，从而可以实现通信频率为小于等于3GHz的第四射频信号的发射。
场景二：毫米波段和现有4G通信频段共用。
在本申请实施例中，当收发装置工作在6GHz以下的通信频段时，例如，接收通信频率为6GHz以下的射频信号时，通过第一模拟信号处理模块(相当于现有技术中的零中频接收架构)来实现；又例如，发射通信频率为6GHz以下的射频信号时，通过第二模拟信号处理模块(相当于现有技术中的零中频发射架构)来实现。当收发装置工作在毫米波段时，例如，接收毫米波段的射频信号时，通过至少两个第一射频信号处理模块和第一模拟信号处理模块(也即：“二次”下变频的结构)来实现；又例如，发射毫米波段的射频信号时，通过至少两个第四射频信号处理模块和第二模拟信号处理模块(也即：“二次”上变频的结构)来实现。
可以理解的是，本申请所提出的收发装置可以让6GHz以下的通信频段重用4G的架构。
场景三：支持毫米波通信频段，同时支持15GHz和60GHz。
现有技术中，为了满足零中频收发架构或者二次变频的超外差收发装置能够同时支持第一频率和第二频率的通信频段，其中，第一频率和第二频率之间的差值大于设定好的目标阈值，例如，第一频率15GHz，第二频率为60GHz，需要保证本振信号的频率位于15GHz-60GHz之间，该带宽很大，这无疑增大了设计难度。
采用本申请所描述的收发装置，当收发装置工作在15GHz的通信频段时，例如，接收通信频率为15GHz的射频信号时，通过第一模拟信号处理模块(相当于现有技术中的零中频接收架构)来实现；又例如，发射通信频率为15GHz的射频信号时，通过第二模拟信号处理模块(相当于现有技术中的零中频发射架构)来实现。当收发装置工作在60GHz的通信频段时，例如，接收通信频率为60GHz射频信号时，通过至少两个第一射频信号处理模块和第一模拟信号处理模块(也即：“二次”下变频的结构)来实现；又例如，发射通信频率为60GHz射频信号时，通过至少两个第四射频信号处理模块和第二模拟信号处理模块(也即：“二次”上变频的结构)来实现。在整个实现过程中，可以通过窄带的频率源来提供本振信号，降低了设计难度。
总的来说，本申请提供的收发装置，因其采用了复用的结构，在开关的切换下，可以实现不同通信频率的射频信号的接收和发射。
