二、数字信号调制仿真简介

1 平台概述

1.1 平台简介

信号调制仿真平台是对在通信中对信号传输进行调制并仿真出其频谱图的平台。该平台用于模拟通信系统中调制信号并仿真出频谱图，主要有幅度调制、角度调制、数字调制及自适应均衡，在相应的调制模块下，用户通过输入相应的参数即可得到输出结果。是集信息采集、处理、加工、传播的重要处理平台。

1.2 操作和界面解说

主要是对软件的基本的操作的内容和信息进行介绍的操作，帮助使用者更好的使用软件平台。

1.3 登录页面介绍

1.3.1 登录平台

操作方法

在matlab环境下双击平台的图标就会出现以下的界面，您在进入平台后，会看到平台的主页面，如图：

该界面是平台的主要的操作界面，根据界面的展示，使用者可以更好的操作软件平台了。

功能按钮区：使用者可以在该区域进行软件的操作与使用。

平台提示区域：对平台的操作进行提示的区域。

2平台功能

2.1幅度调制

幅度调制是使正弦载波的幅度随着调制信号做线性变化的过程，主要包括以下四种调制方式: DSB-AM、普通AM、SSB-AM、残留边带幅度调制。点击功能按钮就会出现以下界面了。

2.2角度调制

角度调制是一种非线性调制方法，通常是载波的频率或相位随着基带信号变化。主要包括频率调制和相位调制。点击功能按钮就会出现以下界面了。

2.3数字调制

数字调制是将基带数字信号变换成适合带通型信道传输的处理方式。在数字通带传输中，数字基带波形可用来调制正弦波的幅度、频率和相位，分别称为数字调幅、数字调频、数字调相。点击功能按钮就会出现以下界面了。

2.4自适应均衡

自适应均衡器能够自动地调节系数从而跟踪信号，主要有RLS (递归最小二乘算法) CMA (常模盲均衡算法)。点击功能按钮就会出现以下界面了。

2.5平台管理

平台设置模块主要是对平台的主要操作进行设置的管理模块。

2.5.1退出平台

点击退出平台按钮，就给出相应提示，是否确定要退出平台，确定退出，直接点击退出平台按钮，则平台就会关闭，如需再次使用平台，则会回到我们的第一步操作，就是点击桌面的图标即可。
