摘要
为实现数据的高速解调,提出了一种QPSK并行解调模型,并对定时同步、载波同步、自动增益控制(AGC)和数据恢复等各个模块进行了Matlab仿真分析。重点提出并仿真实现了一种在并行解调中实现载波同步后的模糊统一和数据恢复的方法。
In order to implement high-speed data demodulation,parallel demodulation model for QPSK signals is proposed,and the parts of the model including timing synchronization,carrier synchro-nization,automantic gain control (AGC) and data recovery are simulated. Especially,a method for phase ambiguity unifying and data recovery after carrier synchronization in parallel demodulation is put forward and simulated.
