Combined with linear modulation system application background designs a simple structure and good performanced linear modulation signal generator. It realize the comprehensive function signal generator. This thesis mainly research contents include: First, research the status of the signal generator and development and the status quo of MATLAB simulation technology. It also introduced the practicability and reliability of MATLAB simulation . Second, study the conventional modulation signal FSK signal and itinerary signal, PSK theories,it layed the foundation for the signal generation. Third, use the example of linear modulation to study three methods of MATLAB simulation, compare their advantages and disadvantages, and decided to use Simulink conduct simulation. Four, using Simulink simulate linear modulation system simulation, realize of the software design, and testing system,finally, make system index demand.
