Minimum mean square error estimationA novel single-channel technique was proposed based on a minimum mean square error (MMSE) estimator to enhance short-time spectral amplitude (STSA) in the Discrete Fourier Transform (DFT) domain. In the present contribution, a Weibull distribution was used to ...

我们需要一些衡量指标去判断一个估计量好与不好,一个很自然的指标就是均方误差(mean square error, MSE)准则,其定义为 mse(\hat{\theta})=E[(\hat{\theta}-\theta)^2] \\ 它度量了估计量偏离真实值的平均偏差的统计平均值。 然而,采用这个指标导致所求的最优估计量可能是不能实现的,因为它不是只关于数...
