摘要
π/4-DQPSK调制方式由于具有频谱利用率高、抗衰落性能强等突出特点,广泛应用于现代通信系统中。文章介绍一种基于π/4-DQPSK方式的调制解调器,重点讨论了其调制原理、软件设计和工程实现。
π/4-DOPSK is widely used in modem communication system because of its many advantages such as high utilization of frequency spectrum and the superior anti-fading performance. In this paper, a Modem based on π /4-DQPSK is presented which includes the principles of modulation and demodulation, software design and implementation.
