The adaptive detector on the base of the Minimum Mean-Square Error (MMSE) principle has got a widely research. In order to speed the convergence, several modified methods have been raised,and the Least Mean Fourth (LMF) algorithm is one of them.

• 基于最小均方误差(MMSE)准则的自适应检测器已经得到广泛的研究,为了加快收敛速度人们提出了许多改进方法,四阶误差最小化(LMF)算法就是其中之一。
