Well, we could try to minimize a squareerror like we did before.
我们可以试着最小化这个平方误差。

However, two-stage estimates of regression coefficients corresponding to these two estimates have approximate equal mean squareerror.
对应于方差参数这两种估计的回归系数的两种两步估计，它们的均方误差大致相当。

It is noted that the minimum mean squareerror (MMSE) detector often loses phase to lock a desired signal when the desired signal dips into a deep fade.
