Using MATLAB: In Communication systemUsing Graphical User Interface (GUI)Step1:1- Double-sideband suppressed-carrier transmission (DSB-SC)2- Double-sideband-large carrier transmission (DSB-LC)3- Upper single sideband (U-SSB)4- Lower single sideband (L-SSB)Step2 :

• Allow the user First to Chose from Amplitude Modulation (Am) or Angel Modulation, Then if the User Chose Amplitude Modulation the Program should allow the User to choose Between This :

[ DSB-SC or DSB-LC or U-SSB or L-SSB ]*Here Better way to use pop up menu for user to choose. (or any method)

• If the user chooses Angel modulation the program should ask user to

           chose [FM or PM] frequency modulation(FM) or phase modulation(PM)step 3:

• Then depend on what the user chose First. Now the user should Enter this box’s

           FM(frequency of message ) ,AM(amplitude of message ) ,           FC(frequency of carrier),AC(amplitude of carrier) , (INDEX)       Then the user should Enter all the parameter needed ,      Then create a RUN Bottom .

• If the user press the RUN bottom the Hidden Codes should do the Modulation and Demodulation after that they have to show the original Message and reconstructed Message in two windows(to modify that all techniques working well )
