摘要
设计了一种采用软硬件结合实现2PSK调制的新方法。介绍了2PSK调制的基本原理及其相对于2FSK、2ASK的优点。给出了调制系统总体方案,详细叙述了FPGA芯片工作的外围电路的设计,并在QuartusII软件环境下进行了系统仿真,结果表明该方法能简化传统调制器的设计。最后阐述了此技术有待继续提高和完善的方向。
A software and hardware implementation of 2PSK modulation module is designed. The paper firstly introduces the basic theory of 2PSK modulation and the advantage compared to 2FSK and 2ASK , then researches the collective scheme and the design of outside circuit, cooperating with the work of FPGA. The system is simulated by using the QuartusII software. The outcome testifies the design of the tradi- tional modulator is simplified . Finally , the aspects improved and perfected is illuminated.
