摘要
二进制绝对相位键控(2CPSK),是数字通信系统中使用的一种信号调制方式。2CPSK的基本原理是利用数字基带信号控制载波相位的变化来达到传送数字信息的目的。这里详细介绍了基于FPGA的2CPSK信号的原理、设计和调试,并且通过QUARTUSII软件,在基于FPGA的实验板上设计了一种新的2CPSK信号的调制解调系统。并调试出结果,结果表明此设计能有效简化传统系统的设计,缩短整个系统设计周期,具有良好的实用性和较强的可操作性。
2CPSK—Binary absolute Phase shift keying,is an modulation mode in digital communication 2CPSK,principally with digital baseband signal,controls the changes of carrier phase and thus transmits the digital information.The paper describes the principle,design and debug process of 2CPSK.And with QUARTUSII software,a new 2CPSK modulation/demodulation system is designed on the FPGA experimental board,and the debugging results indicate that this design could effectively simplify traditional modulator/demodulator,shorten the period of system design,and is of good practical bility and strong operability.
