提出一种新的基于累积量极值的非线性系统盲反卷积算法.通过引入中间变量作为隐含观测量
反卷积系统估计转化为两个子系统估计问题.第一个子系统估计是一具有完备指导信号训练集的后非线性系统(post nonlinear system)辨识
第二个子系统的估计则是一般基于累积量极值的线性系统盲反卷积.与其它算法比较
新算法具有明确的收敛性质和快速的收敛速度.
A new cumulate extrema-based algorithm
for blind deconvolution of the sandwich nonlinear system
is developed.By introducing the intermediate variable as hidden variable
the learning of deconvloution system is fulfilled with an iteration learning process of two parts.The first part is a conventional learning of the post nonlinear system (PNS) with complete training sets
and the second part is in fact equivalent to blind deconvolution of a linear system.Compared with the other algorithm
the new algorithm has a faster convergence speed.
