摘要
分析了MSK信号的谱相关特性,在此基础上提出了一种基于循环谱的MSK信号载频和波特率估计算法,通过对算法渐近特性和消失特性的分析,得出了算法随数据采样点T的增加以速率O(1/T)收敛的结论。计算机仿真实验证明了该算法在低信噪比下具有较好的性能。
This paper proposes a method for parameter estimation for MSK signal, which is based on the analysis of the spectral correlation properties of MSK signal. The asymptotic and vanishing characteristics has been studied and it is concluded that the method exhibits a convergence rate of O（1/T） （T the number of samples）.This method shows higher performance in low SNR, which has been proved by computer simulations.
