摘要

本文分析了利用循环平稳方法估计离散时间时变幅值复线性调频（ＬＦＭ）信号参数的渐近统计性能，表明所得的时变幅值ＬＦＭ信号参数估计的均方差与相应的ＣｒａｍｅｒＲａｏ界关于Ｔ的收敛性具有相同的数量级．模拟结果验证了所得结果的正确性．

Abstract

The concern here is to use cyclostationary approach to estimate the parameters of a complex linear FM signal with time varying amplitude from noisy observation.The asymptotic performance is analyzed and the variance of the estimates is shown to be the same order of magnitude as their Cramer Rao bounds.The statistical analysis is verified by simulations.
