| 摘 要： | 根据BPSK调制解调器的基本理论,采用DDS（直接数字合成）技术在不同频率信号的切换时能保持相位连续的优点来设计BPSK调制模型,用Matlab/Simulink下的Altera DSP Builder工具箱内的模块对直接数字频率合成器DDS（Direct Digital Synthesizer）进行建模;并基于该DDS模块实现BPSK（二进制相移键控）调制器和解调器的设计,在Simulink下对此模型进行仿真,验证了模型的正确性。此设计简化了系统的设计过程,提高了BPSK调制解调系统的可靠性与灵活性,而且修改方便、成本低,对硬件理论知识要求不高,实现起来容易,加快了开发速度。

| Abstract: | 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 ... |
