Linear minimum variance estimate and optimally weighted LS estimate are often used in many fields such as signal processing, control and communications.
在信号处理、控制和通讯等技术领域，常常使用线性最小方差估计和最优加权最小二乘估计对参数作出估计。
In the linear case, it is the same as the minimum variance parameter adaptive control.
在线性情形，它与最小方差参数自适应控制律一致。
