摘要
结合计算机技术,基于高速复杂可编程逻辑器件(CPLD)设计出一种正交I、Q双通道的任意波形发生器,同时给出了协调其工作的软件设计.利用该波形发生器产生FSK/PPM复合调制信号,经过实验验证得到较好的结果.
Combining with computer technique, based on CPLD, an arbitrary waveform generator with I、Q double channel was designed and the software design that makes it work was provided. Finally, the waveform generator is used to produce FSK/PPM hybrid modulation signal and better performance is obtained.
