Location finding for CDMA subscribers using an antenna array at the base station is studied. Two methods are considered for radio location that are based on time of arrival (TOA) and angle of arrival (AOA) measurements. For TOA estimates, a maximum likelih ...
Commercial applications for the location of subscribers of wireless services continue to expand. Consequently, finding the Cramer–Rao lower bound (CRLB), which serves as an optimality criterion for the location estimation problem, is of interest. In this p ...

Speaker direction finding techniques have aroused interests due to achieving the capability of receiving high-quality dis- tant signals. Interesting concepts can be achieved through the comparison of such techniques whereby importance is in achieving high ...
We provide a formal model for identification schemes. Under this model, we give strong definitions for security and privacy. Our model captures the notion of a powerful adversary who can monitor all communications, trace tags within a limited period of tim ...
Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...
We consider the problem of node positioning in ad hoc networks. We propose a distributed, infrastructure- free positioning algorithm that does not rely on GPS (Global Positioning System). Instead, the algorithm uses the distances between the nodes to build ...
Location finding for CDMA subscribers using an antenna array at the base station and deploying multiple base stations is studied in this paper. Two methods are considered for radio location: measured time-of-arrival (TOA) and angle-of-arrival (AOA), and al ...
The cavity ring-down technique is applied to an industrial-scale radio-frequency (rf) plasma reactor for the measurement of the density and spatial profile of negative ions in pure oxygen and hydrogen rf plasmas, and for the detection of nanometric particl ...
Wireless location finding is receiving increasing attention in the field of wireless communications. This is is due to an order issued by the Federal Communications Commission (FCC) that mandates all wireless service providers to locate an emergency 911 ca ...
Wireless location finding is gaining considerable attention in the field of wireless communications. This is due to a recent USA government mandate for wireless service providers to locate users in emergency situations within a high precision. In this pape ...
