摘要

Parameter estimation based on binary quantized observations is consideredgiven the estimation system does not know which of a set of quantizers wasused, without replacement, for each block of observations. Thus the estimationsystem receives permutated blocks of quantized samples of a signal in noisewith unknown signal amplitude. Maximum likelihood (ML) estimators are utilizedto estimate both the permutation matrix and unknown signal amplitude underarbitrary, but known, signal shape and quantizer thresholds. Sufficientconditions are provided under which an ML estimator can be found in polynomialtime. In addition, model identifiability is also studied, and an alternatingmaximization algorithm is proposed to solve the general problem via goodinitial estimates. Finally numerical simulations are performed to evaluate theperformances of the ML estimators.
