2.部分核心代碼

clear variables;
close all;

 

load('TrainingData.mat');
load('ValidationData.mat');

%% Define training parameters

MiniBatchSize = 1000;
MaxEpochs = 100;
InputSize = 2*NumOFDMsym*NumSC;
NumHiddenUnits = 16;
NumClass = length(Label);

 

Layers = [ ...
    sequenceInputLayer(InputSize)
    lstmLayer(NumHiddenUnits,'OutputMode','last')
    fullyConnectedLayer(NumClass)
    softmaxLayer
    classificationLayer];

 

Options = trainingOptions('adam',...
    'InitialLearnRate',0.01,...
    'ValidationData',{XValid,YValid}, ...

%% Train DNN

Net = trainNetwork(XTrain,YTrain,Layers,Options);
