family:'trebuchet ms', verdana, arial, tahoma;font-size:14px;line-height:25px;white-space:normal;background-color:#FFFFFF;">最小均方误差(MMSE) 估计介绍其中最小化均方误差 (MSE),是一项共同措施的估计质量的方法。MMSE 估计然后定义为实现最低限度的 MSE 的估计。


我们对利用 MMSE 算法的信道估计的方法,在我们工作查找与所需的每个函数值的最低值和平方的原则。主要的想法是通道脉冲响应的预期和实际值之间的差异。


通道脉冲响应的估计的值的计算使用的投入、 产出和关联过程中的噪音的协方差。此估计值和脉冲响应的实际值然后在一起比较,找出估计错误。因此 MMSE 估计能达到通过后续迭代误差的最小平方的值。
