现代通信越来越依靠全数字处理技术, 通信系统中的全数字调制解调意味着发射机 及接收机将全部采用数字信号处理(DSP) 算法, 从而整个通信系统就可以用DSP 芯片或超 大规模集成电路(VL S I) 器件来实现。对全数字BPSK 调制解调系统采用计算机仿真的方法 进行研究能清楚地了解通信系统中所运用的数字信号处理技术, 包括信息源、发送和接收 滤波器、内插器以及判决器等全部采用数字信号处理算法来实现。文章给出了BPSK 调制 解调系统各个模块的算法和结构, 运用MA TLAB 软件进行了仿真, 得出了各个部分的时域 和频域波形图, 系统仿真的设计方法对Q PSK、16QAM 等全数字调制解调系统的硬件实现 具有实际的指导意义。()
