The Asymptotic Efficiency of Simulation Estimators

Operations Research, 1992
A decision-theoretic framework is proposed for evaluating the efficiency of simulation estimators. The framework includes the cost of obtaining the estimate as well as the cost of acting based on the estimate. The cost of obtaining the estimate and the estimate itself are represented as realizations of jointly distributed stochastic processes. In this

Optimum Multiuser Asymptotic Efficiency

IRE Transactions on Communications Systems, 1986
The degradation in bit error rate due to the presence of multiple-access interference in a white Gaussian channel can be measured by the multiuser asymptotic efficiency, defined as the ratio between the SNR required to achieve the same uncoded bit error rate in the absence of interfering users and the actual SNR.

Asymptotic relative efficiency

, 2012
The purpose of asymptotic relative efficiency is to compare two statistical procedures by comparing the sample sizes, n1 and n2, say, at which those procedures achieve some given measure of performance; the ratio n2/n1 is called the relative efficiency of procedure one with respect to procedure two.

On Asymptotic Efficiency for Asynchronous CDMA

2007 41st Annual Conference on Information Sciences and Systems, 2007
We consider asynchronous CDMA systems and analyze their performances in terms of asymptotic efficiency when linear receivers are employed and the system becomes overloaded. We show that in such systems, differently from synchronous systems, linear detectors can be asymptotically efficient and, specifically, that the MMSE detector is asymptotically ...

Asymptotically efficient quantizing

IEEE Transactions on Information Theory, 1968
It is shown, under weak assumptions on the density function of a random variable and under weak assumptions on the error criterion, that uniform quantizing yields an output entropy which asymptotically is smaller than that for any other quantizer, independent of the density function or the error criterion. The asymptotic behavior of the rate distortion

On the asymptotic efficiencies of robust detectors

IEEE Transactions on Information Theory, 1992
Summary: Two methods are considered for comparing the asymptotic efficiencies of robust detectors in the problem of detecting coherent signals in additive noise. The first of these methods considers the relative detector sample sizes for a fixed value of the detector power, while the second method considers the relative detector sample sizes for a ...

Asymptotic Efficiency of Inverse Estimators

Theory of Probability & Its Applications, 2000
Summary: Inverse estimation concerns the recovery of an unknown input signal from blurred observations on a known transformation of that signal. The estimators considered in this paper are based on a regularized inverse of the transformation involved, employing a Hilbert space set-up. We focus on properties related to weak convergence. It is shown that
