Abstract--This paper addresses pilot-assisted channel estimation for wireless orthogonal frequency division multiplexing (OFDM) systems with irregular pilot arrangements. Using non...
Asynchronous design has been the focus of renewed interest. However, a key bottleneck is the lack of high-quality CAD tools for the synthesis of large-scale systems which also all...
Abstract. In this paper, reverse partially-marked safe net condition/event systems (RsNCES) are introduced, rules of their functioning are defined and convenient interpretation met...
I consider the problem of finding all the modes of a mixture of multivariate Gaussian distributions, which has applications in clustering and regression. I derive exact formulas f...
Abstract. Most distributed power control algorithms have been proposed assuming constant interference and constant path gain. These considerations may result in lower performance g...
