MMSE estimation from quantized observations in the nonasymptotic regime
This thesis studies MMSE estimation on the basis of quantized noisy observations. It presents nonasymptotic bounds on MMSE regret due to quantization for two settings: (1) estimation of a scalar random variable given a quantized vector of n conditionally independent observations, and (2) estimation …

Adaptive MMSE multiuser receivers in MIMO OFDM wireless communication systems
… famous paper of 1999. Implementing the Adaptive MMSE Receivers in MIMO OFDM systems which I refer to (AMUD MIMO OFDM), combines the adaptive minimum mean square error multiuser receiver's scheme with prior information of the channel and interference cancelation in the spatial domain, achieves …

Differential MMSE: A New Approach for Adaptive Interference Suppression Over Time-Varying Channels
The use of the linear minimum mean square error (MMSE) criterion to design coherent adaptive receivers is a classical method for interference suppression, with applications ranging from equalization to adaptive multiuser detection for direct sequence code division multiple access (CDMA) systems. A …

Bayesian Estimators, Error Bounds, and Applications to Imaging
… value of the MSE is obtained by the so-called MMSE estimator (MMSEE), which in this sense is the best possible estimator. In general, the MMSE as well as the MMSEE are difficult to compute, which gave early impetus to work on a host of bounds on the MMSE of varying degrees of tightness over the …

The Influence of Health Concern on the Relationship between Lifestyle Activities and Cognition in the Elderly
… version of the Mini-Mental State Examination (K-MMSE). A cross-sectional, factorial design was used in which the K-MMSE score was the dependent variable, with physical, mental, and social activity as one factor and health concern as the other. Analysis of covariance revealed significant …

The Limits of Recovering Planted Subgraphs
… is to understand the minimum mean squared error (MMSE), defined in terms of recovering the edges of H*, as a function of p and H, for large n. A recent paper [MNS⁺23] characterizes the graphs for which the limiting (as n grows) MMSE curve undergoes a sharp phase transition from 0 to 1 as p …
