Description

一种信号处理方法以及相关设备和装置 技术领域
本发明涉及通信领域， 尤其涉及一种信号处理方法以及相关设备和装置。
背景技术
在通信领域中， 所有设备之间要进行消息交互， 就必须通过发送信号来实 现。 信号是运载消息的工具， 是消息的载体， 是一种可以觉察的物理量或脉冲 (如电压、 电流、 磁场强度等）， 通过它们能传达消息或信息。
随着人们日益增长的体验需求，便要求信号的传输速度越快越好， 理论上 来讲， 只要承载信号传输的介质越来越宽， 那么一次性传输的信号就越多， 从 而速度就越快， 但是， 由于电平等物理原因， 和目前的技术而言， 人们能够处 理的脉冲波动频率有限， 目前 cable领域， 基本上使用的频分复用的技术， 将 传输信号的下行频段和上行频段分开。例如， 已经使用的有线电缆数据服务接 口规范 (Data Over Cable Service Interface Specifications, Docsis) 3.0标准， 美标 定义： US: 5MHZ ~ 42MHZ, DS: 57MHZ ~ 1002MHZ;欧标定义： US: 5MHZ ~ 65MHZ ， DS: 87MHZ - 1002MHZ, 目前最新的 Docsis 3.1技术重新划分了 上下行频谱， US: 5MHZ - 204MHZ ， DS: 258MHZ ~ 1200MHZ ( US为上行 信号， DS为下行信号）。 既然不能^ ^容易地改变能够处理的脉冲波动频率， 那 么如何对上行信号和下行信号进行合理灵活地分割便成了人们攻克问题的另 一方式。
现有技术是一款设备一次只支持一种混频规格， 例如 42MHZ/55MHZ,后 续如果要重新划分频段， 需要到设备现场更换成新的混频规格， 例如 65MHZ/87MHZ, 或者 87MHZ/108MHZ或者 204MHZ/258MHZ等等。 这样， 当需要更换信号频段的时候， 需要人工手动去设置， 非常不智能， 不灵活， 而 且资源消耗大。

本发明实施例提供了一种信号处理方法以及相关设备和装置， 用于下行、 上行信号传输时， 按照需求智能更换信号的频段。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域技术人员在没有作出创造性劳 动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
请参照图 1， 本发明实施例中下行信号处理方法一个实施例包括：
101、 第一滤波设备将下行信号按照预置的规则分割成第一下行信号和第 二下行信号， 所述第二下行信号为满足预置标准定义的信号；
由于实际上能够处理的最大波动频率信号远远小于在物理介质上传输的 信号， 所以第一滤波设备首先要将接收到传输信号进行分割，得到能够进行信 号处理的第二下行信号。
102、 第一滤波设备对第二下行信号进行模数转换， 得到第三下行信号； 因为处理器内部能够处理的信号是数字信号， 而下行信号是模拟信号， 分 割得到的第二下行信号也是模拟信号， 所以在对信号进行处理之前， 先要把模 拟信号转换成数字信号。
103、 第一滤波设备将第三下行信号进行滤波， 得到第四下行信号； 滤波得到的第四下行信号为用户需求频段的信号或者是终端需要的合理 频段信号，预置需求频段可以是人工设置，也可以根据网路实际情况智能转换， 可以是可实现的任意频段。
104、 第一滤波设备将第四下行信号进行数模转换， 得到第五下行信号； 处理完之后的数字信号， 因为要用于驱动其他设备， 所以要将数字信号转 换成模拟信号。
105、 第一滤波设备将第一下行信号和第五下行信号合成得到下行输出信 号；
为了使第五下行信号正常输出，则需要将第一下行信号和第五下行信号合 成达到正常输出标准的波动频率。

下行信号理论可达到的波动频率超过 1GHZ， 但根据 Docsis 标准， 实际 能够处理的下行信号最大波动频率为 204MHZ或 258MHZ, 所以， 首先要对 下行信号进行分割，得到能够处理的最大波动频率的第二下行信号， 另要说明 的是， 由于现有技术受限， 能够处理的信号波动频率为 204MHZ或 258MHZ, 若有新的技术更新，能够处理的信号波动频率更大或者出现了其他的信号波动 频率标准， 依然属于本发明的保护范围， 此处不作限定。
202、 第一滤波设备将第一下行信号调整为可输入电平值信号。
为了使得最后的输入信号更强，在输出之前可以先将下行输出信号输入到 放大器放大， 所以在此之前， 需要调整第一下行信号的电平值， 使得第一下行 信号为可输入电平信号。 203、 第一滤波设备对第二下行信号进行模数转换， 得到第三下行信号； 因为处理器内部能够处理的信号是数字信号， 而下行信号是模拟信号， 分 割得到的第二下行信号也是模拟信号， 所以在对信号进行处理之前， 先要把模 拟信号转换成数字信号。

108MHZ ~ 204MHZ等等。
205、 第一滤波设备将第四下行信号进行数模转换， 得到第五下行信号； 处理完之后的数字信号， 因为要用于驱动其他设备， 所以要将数字信号转 换成模拟信号。
206、 第一滤波设备将第一下行信号和第五下行信号合成得到下行输出信 号；
为了使第五下行信号正常输出，则需要将第一下行信号和第五下行信号合 成达到正常输出标准的波动频率。
207、 第一滤波设备将下行输出信号放大；
为了使得输出信号更强， 在输出之前可以对下行输出信号进行放大。
208、 第一滤波设备将下行输出信号发送给分配设备；
将经过处理后所得到的完整的下行输出信号发送给分配设备，分配设备即 可对接收到的信号进行分配等处理。

根据 Docsis 标准， 实际能够处理的上行信号最大波动频率为 204MHZ或
258MHZ, 但接收到的上行信号包含了真个频段范围， 远大于能够处理的上行 信号频段， 所以， 首先要对上行信号进行分割， 得到能够处理的最大波动频率 的第二上行信号， 另要说明的是， 由于现有技术受限， 能够处理的信号波动频 率为 204MHZ或 258MHZ, 若有新的技术更新， 能够处理的信号波动频率更 大或者出现了其他的信号波动频率标准，依然属于本发明的保护范围， 此处不 作限定。
