【数字信号调制】数字信号调制仿真平台含Matlab源码（信号调制与解调的matlab仿真设计）

1 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。

function varargout = CMA(varargin)% CMA MATLAB code for CMA.fig% CMA, by itself, creates a new CMA or raises the existing% singleton*.%% H = CMA returns the handle to a new CMA or the handle to% the existing singleton*.%% CMA('CALLBACK',hObject,eventData,handles,...) calls the local% function named CALLBACK in CMA.M with the given input arguments.%% CMA('Property','Value',...) creates a new CMA or raises the% existing singleton*.
