When a dense set of array response measurements without angle of arrival labels are available, self calibration is shown to be possible using an unsupervised manifold learning step and a supervised step that uses measurements associated to a single s

This paper describes a low-cost real-time geo location system that uses two multiple-antenna sites to provide secondary surveillance at small to medium size airports. Tower controllers at these airports currently rely primarily on visual surveillance

In the censoring approach to decentralized detection, sensors transmit real-valued functions of their observations when "informative" and save energy by not transmitting otherwise. We address several practical issues in the design of censoring sensor

In this paper, we focus on the total-system-energy minimization of a wireless image transmission system including both digital and analog components. Traditionally, digital power consumption has been ignored in system design, since transmit power has

On small platforms, angle-of-arrival (AOA) estimation of an E-M signal can be accomplished with colocated antennas measuring multiple components of the propagating wave. An electrically small vector sensor (VS) antenna constructed above and below the

Due to inherent factors such as a small and fragmented market and rapid hardware obsolescence, the conventional textbook is inadequate for DSP laboratory education. Freely available open-content materials that enable and promote both local customizat

In this paper, we examine decentralized detection problems in which a send/no-send rate (censoring rate) on the sensor decisions replaces the communication constraint of D-level sensor decisions in canonical parallel decentralized detection problems.

Due to high data rates and limited bandwidth as well as limited battery power, wireless multimedia communications systems must be optimized in every possible way. We develop a generic matching scheme for wireless image and video communication in whic
