According to the basic theory of BPSK modem and based on the advantage that the DDS(Direct Digital Synthesis) technology could maintain the phase continuity in the switch-over of different frequency code,the BPSK modulation model is designed,and by using the modules in Altera DSP Builder toolbox,the direct digital synthesizer under Matlab or Simulink,is modeled,thus the BPSK modem based on DDS module is implemented.Meanwhile,the BPSK modem is simulated with the Simulink,the simulation result shows that the system is effeetive.This method simplifies the design progress,enhances reliability and flexibility of the BPSK modem system.Moreover,the system is convenient in revision,low in cost and hardware theory knowledge request,and easy in implementation,thus speeding up the development.
