| 摘 要： | 对盲均衡（盲解卷积）提出了两种三阶累积量的基本算法，在算法中依据非因果的ＡＲ（自回归）模型及与逆滤波器系数相关的方程，把非最小相位系统的盲均衡问题转化为解相应的线性方程组的问题，保证了这种解法的唯一性。在算法中仅利用了累积量的对角线切片，从而使该算法简单、准确。仿真实验结果表明，该算法是可行有效的

| Abstract: | Two 3rd order cumulant based algorithms for blind equalization (blind deconvolution) are presented.In the algorithms,based on a noncausal AR model and an equation relating to the inverse filter coefficients, the problem of blind equalization of non minimum phase systems is reduced to that of solving the corresponding set of linear equations.Thus the uniqueness of solution can be guaranteed. Furthermore,only the diagonal slices of cumulants are employed in the algorithms,which results in algorithms being simpler and more accurate.The results of simulations confirm the feasibility and efficiency of the algorithms. |
