⛄ 内容介绍
采用基于决策论的方法,对7种通信调制信号进行识别.利用MATLAB对AM,DSB,SSB,2ASK,2FSK,2PSK,4PSK进行特征提取,根据不同信号在瞬时相位,瞬时幅度,瞬时频率上的不同特征识别出各种信号.
⛄ 部分代码
% MODULATING_SYSTEM MATLAB code for Modulating_System.fig
% MODULATING_SYSTEM, by itself, creates a new MODULATING_SYSTEM or raises the existing
% singleton*.
%
% H = MODULATING_SYSTEM returns the handle to a new MODULATING_SYSTEM or the handle to
% the existing singleton*.
%
% MODULATING_SYSTEM('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MODULATING_SYSTEM.M with the given input arguments.
%
% MODULATING_SYSTEM('Property','Value',...) creates a new MODULATING_SYSTEM or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Modulating_System_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Modulating_System_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
