Simulation design of a transmitter based on SR

The traditional radio transmitter relies more on hardware,which brings a lot of inconvenience to practical application.The SR(software-defined radio) can solve this problem very well.With digital signal process as the core and modern communication theory as its foundation,the problem of SR transmitter is researched,and the simulation system of a SR transmitter is designed as well.The simulation results possess theoretical guidance in constructing a real SR transmitter.
