摘要
针对高动态环境下频率和频率变化率的估计问题,本文分析了常用的载波同步的帧结构及方法,并在此基础上为满足估计频率变化率的要求提出了一种间插式帧结构及算法,仿真表明此算法有很好的估计精度和性能。
To estimate the frequency and the frequency change rate in the high dynamic environment, the author analyzes some commonly used frame structures and methods of carrier synchronization in this paper. And on this basis, an interleaved frame structure and algorithm are proposed to meet the requirement of frequency-rate estimation, which is validated by simulations with high estimation accuracy and performance.
