ANALOGICAL PRE-ESTIMATOR FOR ENHANCED MAXIMUM LIKELIHOOD ESTIMATOR (MLE) APPLIED TO ULTRASOUND SIGNAL ACCURATE DETECTION

Maurizio Caciotta

Abstract

The convenience to analyze ultrasound signals with a digital trasform is compared with the application of an analogic module extractor. The accuracy the analogical apparatus can reach, is compatible with the optimal input that needs an improved maximum likelihood analysis. The computing heaviness is relieved by the possibility to preestimate the echoes parameters and by the elimination, considering time occurrence, of reflected echoes. The parallel adapting of the recursive algorithm to a hardware parallel structure is discussed to make possible the real time application.
