摘要
通过推导得出了存在载波频差时,有数据辅助时对PSK信号进行载波相位估计时的最佳观测长度,并得到了最佳观测长度下的载波相位估计方差,最后通过仿真对理论分析结果进行了验证。研究成果可以为突发通信系统中的信号设计及同步算法的设计提供依据。
The optimal observation interval, which is determined by the normalized carrier frequency offset, is derived for the data-aided PSK signal carrier phase estimator, and the minimal estimating variance is then obtained. The analysis and simulation result will contribute a lot to the design of burst communication signal and the parameter design of the corresponding synchronization algorithm.
