ddp.m

对文本文件和音频文件进行OFDM调制和16QAM调制的matlab仿真。

function varargout = DDP(varargin)
% DDP M-file for DDP.fig
%      DDP, by itself, creates a new DDP or raises the existing
%      singleton*.
%
%      H = DDP returns the handle to a new DDP or the handle to
%      the existing singleton*.
%
%      DDP('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in DDP.M with the given input arguments.
%
%      DDP('Property','Value',...) creates a new DDP or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before DDP_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to DDP_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
