摘要
在PSK信号解调时,并不一定已知信号的参数信息,因此,盲解调技术具有重要的应用价值。文中介绍了一种平方法估计载频、延迟相乘法估计码元速率,并利用锁相环技术进行PSK信号盲解调仿真算法。仿真结果表明,该算法有着较好地解调效果。
In demodulating PSK signal,parameters of the signal may be unavailable,as a result of which blind demodulation is very important. This paper briefly introduces a method for estimating carrier frequency by square and estimate symbol rate by delay multiplied and a simulation algorithm for blind demodulation of PSK with phase-locked loop. The simulation indicates that this algorithm has good demodulation effect.
