Research of Modulation and Demodulation of Inbound Signal of Two-way Automatic Communicatio

The paper introduced the basic principle of two-way automatic communication system and method of modulation and demodulation of inbound signal, described method of using FIR filter and data difference method to demodulate inbound signal, and used Matlab/Simulink to establish a simulation model based on distributed network. The simulation research for modulation and demodulation of inbound signal proved the method is correct.
