摘要
本文利用接收信号(为二阶周期平稳信号)的二阶循环平稳特性推导了一种开环频偏估计算法,此算法的特点为:(1)接收信号为MPSK调制信号;(2)频偏估计过程不需要训练序列;(3)适用于任何分布的加性平稳噪声(白噪声及有色噪声)。文章对提出算法的性能进行了分析,并运用蒙特卡洛(MonteCarlo)方法对算法的性能进行仿真。
An open-loop frequency estimation algorithm is proposed based on the received signal's second-order cyclic statistics in this paper (The received signal is second-order cyclic stationary). The feature include in: (1)The received signal is MPSK modulated; (2)It does not need training data; (3)It is tolerant to additive stationary noise of any color or distribution. Performance of the developed method is derived and analyzed using Monte Carlo simulation.
