Localizing an Unknown Number of mmW Transmitters Under Path Loss Model UncertaintiesMar 08 2019This work estimates the position and the transmit power of multiple co-channel wireless transmitters under model uncertainties. The model uncertainties include the number of the targets and the parameters of the path-loss model which enable the system ... More

Almost sure limit theorems on Wiener chaos: the non-central caseJul 23 2018Jan 18 2019In \cite{BNT}, a framework to prove almost sure central limit theorems for sequences $(G_n)$ belonging to the Wiener space was developed, with a particular emphasis of the case where $G_n$ takes the form of a multiple Wiener-It\^o integral with respect ...

Inference on a Distribution Function from Ranked Set SamplesApr 25 2013Oct 14 2013Consider independent observations (X_1,R_1), (X_2,R_2), ..., (X_n,R_n) with random or fixed ranks R_i in {1,2,...,k}, while conditional on R_i = r, the random variable X_i has the same distribution as the r-th order statistic within a random sample of ...
