摘要 本文利用二维循环统计量方法对二维平稳乘性噪声与二维平稳加性噪声共存情况下的二维谐波信号参数估计问题进行了讨论 .利用二维循环统计量能够有效地抑制二维平稳乘性噪声和二维平稳加性噪声的特点 ,有效地从噪声中提取出信号参数 . The problem concerned here is parameter estimation of two-dimensional harmonics in the presence of multiplicative and additive noise. Two-dimensional cyclic statistics which can restrain two-dimensional multiplicative noise and two-dimensional additive noise efficiently are employed to estimate the frequencies and phases. Simulation examples illustrate the algorithm.
