Description

一种发射机、 接收机及射频收发方法 技术领域
本发明涉及无线通讯技术领域， 尤其涉及一种发射机、接收机及射频 收发方法。
背景技术 在现有的通信系统中， 基带芯片与射频电路往往需要协同工作， 其中 射频电路一般负责射频信号的发送或接收，基带芯片一般负责对射频信号 进行一系列的处理， 例如： 在发射机， 基带芯片可以将音频信号编译成用 来发射的射频信号； 在接收机， 基带芯片可以把收到的射频信号解译为音 频信号。 同时， 基带芯片也具备编译 /解译地址信息、 文字信息、 图片信 息等信号处理功能。
其中， 基带芯片还有一项重要的功能是： 通过一系列的复杂算法， 对 流经射频电路的信号进行载波恢复、载波生成等处理，以修正信号的误差， 从而保证射频电路发送 /接收到的射频信号的准确度。 例如：
如图 l a所示， 为现有技术中的一种射频电路架构， 其中的接收机和 发射机集成在了一起， 并与同一个基带芯片相连， 以便于基带芯片对流经 接收机和发射机的信号进行载波恢复、 载波生成等处理。 比如： 如图 l b 所示， 为基带芯片对信号进行载波恢复的大致处理流程， 其中： 基带芯片 通过鉴相器根据判决所得的误差， 获取相位误差， 再通过环路滤波器以及 数字振荡器依据相应的算法处理后， 输出修正了误差的相位信号。
现有技术的问题：
为了能够提高收 /发机的运行效率， 就需要提高射频电路的频谱效率， 而提高调制模式是一个提高频谱效率的主要方式。 但是， 在提高调制模式 后， 例： ¾口： 由 64QAM ( Quadrature Amplitude Modulation , 正交振幅调制） 提高到 1024QAM , 基带芯片也需要增加元件， 以保证载波恢复、 载波生 成等功能能够正常运作。 并且在现有技术中， 想要保证基带芯片在高调制 模式下能够正常运行， 可行的方案只有在基带芯片上集成更多的元件， 例 如： 在 64QAM场景下， 基带芯片需要 26个门电路， 而在 1024QAM场景 下， 就需要 21Q个门电路。 进一步的， 在 2048QAM或 4096QAM等场景 下， 所需要的门电路的数量更加会成指数倍增加， 这在工业制造上是无法 实现的。 并且， 想要在高调制模式下运行， 一个基带芯片上需要增加的元 件不仅仅是门电路， 基带芯片中的其他元件， 也需要成倍增加， 需要消耗 巨大的成本， 且由于元件的增多， 基带芯片运行时的功耗也很大。
使得现有技术中，基带芯片与射频电路在高调制模式下进行载波恢复、 载 波生成时所需的成本 4艮高。 发明内容 本发明的实施例提供一种发射机、接收机及射频收发方法， 能够在射 频电路前端进行载波恢复、载波生成，使得基带芯片不必再承担载波恢复、 载波生成的功能， 从而降低基带芯片的运行成本。

在本发明实施例中， 误码矩阵纠错器可以对发射机 /接收机中产生的 数字编码的误差进行误码纠错。 其中， 接收机中的数字编码的误差主要产 生原因包括： 在与接收机进行数据通信的发射机的硬件链路中， 电信号的 传输会有一定几率产生偏差，从而使接收机根据所接收到的信号生成的数 字编码产生误差； 在无线通讯的空间传输过程中产生的误差； 在接收机的 硬件链路中， 电信号的传输会有一定几率产生偏差， 从而使接收机中的数 字编码产生的误差。 再其中， 发射机中的数字编码的误差主要产生原因包 括： 在发射机的硬件链路中， 电信号的传输会有一定几率产生偏差， 从而 使发射机中的数字编码产生的误差。
需要说明的是，接收机和发射机中的误码矩阵纠错器可以相同。例如： 在误码矩阵纠错器中可以预存标准的信号幅度数字误码矩阵、信号相 位数字误码矩阵、频率源相位数字误码矩阵等通信协议中已经制定的标准 码源， 如： 协议中的标准 QAM码源。 技术人员可以预存在误码矩阵纠错 器中， 以便于误码矩阵纠错器将这些标准数据， 与接收机接收到的或发射 机生成的信号幅度数字编码、 信号相位数字编码、 以及频率源相位数字编 码进行对比， 并输出信号幅度数字误码、 信号相位数字误码、 频率源相位 数字误码。
其中， 信号幅度数字误码、 信号相位数字误码、 频率源相位数字误码 可以有多种形式， 比如： 预存的标准的信号幅度数字编码中的 A段字符是 1010,而接收机根据接收到的射频信号所解析出的信号幅度数字编码中的 A段字符是 1011 , 则误码矩阵纠错器可以通过筒单的二进制加减法获取信 号幅度数字误码， 即为 1011-1010=1。
进一步的， 误码矩阵纠错器中对信号幅度数字编码、信号相位数字编 码、 本振频率源相位误差数字编码进行分析， 并获取相应的纠错控制信号 的过程， 可以有多种， 下面举例说明其中的优选方案：
图 2d所示的是在 64Q AM的场景下， 存在于接收机或发射机的射频电 路中的误码矩阵纠错器对信号幅度数字编码、 信号相位数字编码、 本振频 率源相位误差数字编码进行的分析过程。 其中， 标注了斜线的方块表示的 是信号幅度数字编码所对应的标准码源，标注了网格的方块表示的是信号 相位数字编码所对应的标准码源，标注了全黑色的方块表示的是本振频率 源相位误差数字编码所对应的标准码源，这些标准码源可以是预存在误码 矩阵纠错器中的标准 Q AM码源， 并且这些标准 Q AM码源已被公开在了现 有的协议中， 技术人员可以直接从协议中知晓这些标准 QAM码源。
当射频电路中的信号幅度数字编码传输到了误码矩阵纠错器，误码矩 阵纠错器可以通过现有的技术手段，如通过比较器来对比射频电路中的信 号幅度数字编码和标准 Q A M码源中的信号幅度数字编码， 即误码矩阵纠 错器可以将射频电路中的信号幅度数字编码与图 2d所示的标注了斜线的 方块所对应的数据进行对比， 并通过筒单的二进制加减法获取二者的差 值。 再通过∑ Δ调制器， 根据所获取的差值输出对应的信号幅度纠错控制 模拟信号。 误码矩阵纠错器输出的信号幅度纠错控制模拟信号传输至鉴幅器后， 鉴幅器可以以此对信号幅度数字编码进行矫正。并且上述的误码纠错过程 可以多次循环， 以确保信号幅度数字编码的正确。
同理，误码矩阵纠错器对于信号相位数字编码和本振频率源相位误差 数字编码可以通过上述过程进行处理。 即在本发明实施例中， 误码矩阵纠 错器可以通过上述过程对接收机、 发射机或收发机（如图 6b、 图 6c或图 6d 所示的同时集成了接收和发射功能的射频电路） 中的信号幅度数字编码、 信号相位数字编码和本振频率源相位误差数字编码进行纠错。
需要进一步说明的是， 在本实施例中， 对于 1024QAM、 2048QAM , 4096QAM等场景皆可采用上述的误码纠错过程，从而实现了在 1024QAM、 2048QAM , 4096QAM等场景下进行载波恢复、 载波生成， 并且射频电路 的结构并不会改变， 可以通过现有的工业生产设备制造出来。 进一步的， 本实施例中所述的接收机， 如图 2b所示， 还可以包括： 鉴 相器 26、 相位码生成器 27、 功分器 28 , 其中：
