The Variance of a Linear Combination of Independent Estimators Using Estimated Weights [PDF]
ABSTRACTLet t1,…,tk be independent unbiased estimators of a parameter τ. Let t* = Σαiti have minimum variance among unbiased linear estimators of τ, and let , be any linear combinations with () independent of t1,…,tk. We prove that is unbiased for τ and that the ratio of the variance of to the variance of t* is where is the mean square error of as

Single channel speech-music separation using matching pursuit and spectral masks [PDF]
A single-channel speech music separation algorithm based on matching pursuit (MP) with multiple dictionaries and spectral masks is proposed in this work. A training data for speech and music signals is used to build two sets of magnitude spectral vectors
