基于MATLAB的DVB系统仿真程序

此程序对DVB_T系统进行了较完整的仿真，相信能够很好地帮助初学者，为大家做个向导

%% channel_model Simulates a transmission channel.
%%
%%   y = channel_model（x） transmits a complex data vector with values in
%%   the range of -1:1 over a simulated transmission channel.
%%   The trivial channel model is implemented
%%   i.e. the transmission function is identity.

function data_channel_out = channel_model （data_channel_in）

  % Perform actions
  %data_channel_out = data_channel_in;
  %for t = 280/2560: 280/2560: 2560
     % data_in（t） = data_channel_in;
  data_channel_out = awgn（data_channel_in 50‘measured‘）;
% Add white Gaussian noise.
%c = rayleighchan（1/10000100）;

%data_channel_out = filter（cdata_channel_in）; % Pass signal through channel.
 % Display all properties of the channel object.
