Some Recent Results in Signal Detection.

Abstract
Some recent results on the detection and estimation of signals in the presence of noise are discussed. An exact confidence lower bound is obtained for the discriminatory power of an estimated linear discriminant function for signal detection. Information theoretic criteria are suggested for the estimation of signals. A new method is proposed for determining the number of signals and estimating them in exponential signal models. Keywords: Discriminant function; Exponential signal models; Information criteria in model selection; Prony's method; Signal processing.
