复乘性噪声模型基于累积量的参数估计

Multiplicative complex noise model:parameter estimation using cumulants

文中研究了复乘性噪声模型的参数估计问题，给出了利用乘性观测过程的高阶累积量来估计复信号过程统计性质的一些结果。

We investigate multiplicative noise models of the form z(t)=s(t)g(t)+n(t),where z(t)the observed preress. In this model,s(t)g(t)and n(t)are mutually independent stationary complex random processes,s(t)IS the complex signai process,g(t)is the multiplicative com-plex noise process,and n(t)is a complex Gaussian process.The objective is to estimatesome statistical properties of the complex signal process,s(t),from observations of z(t),byusing of cumulants.
