Figure 3.21: Final Menu for the Uplink Simulator3.5 Code Structure of the SimulatorThis section contains a detailed description of the program files used in the simulator.Most of the code of the simulator was written in MATLAB. The following flowchartsillustrate the file structure of the uplink and downlink simulators:wcdma.mmainmenu.mupuplinkordownlink?downuplink.mdownlink.mupmenu.mdownmenu.mup_sim.mdown_sim.mFigure 3.22a: Simulator Code Structure52
