Recently, ESPRIT-based parameter estimation algorithms have been developed to exploit the structure of signals from strictly second-order (SO) non-circular (NC) sources. They achieve a higher estimation accuracy and can resolve up to twice as many sources. However, these NC methods assume that all the received signals are strictly non-circular. In this paper, we present the C-NC Standard ESPRIT and...
Since wireless communications began to take an abrupt rise, with the development of techniques which were introduced for the growth of data transfer, antenna systems were considered to be the ideal choice to obtain the wanted results. Nevertheless these techniques required the development of certain algorithms also, to facilitate the recognition of the signals at the reception side (direction of arrival...
In this paper we present a Direction-of-Arrival (DoA) based system which is used for indoor positioning applications. The proposed system has been designed for locating transmitter tags/mobile phones in open indoor locations, such as conference centers, expo areas, and warehouses. A description of both the system architecture and the DoA-based indoor-positioning algorithm are given. In order to demonstrate...
