Radiolocation in Cellular Systems

Описание:
This book focuses on the techniques and schemes to improve radiolocation accuracy in cellular systems. In particular, it considers the estimation of the signal time of arrival (TOA) and the angle of arrival (AOA). Conventional radiolocation schemes estimate TOA or AOA individually in several base stations (BS’s). In this book, a single BS radiolocation scheme is presented to enable more accurate position estimation in NLOS environment. By adopting joint angle and delay estimation (JADE), this scheme can also work properly with the existence of multipath. Furthermore, in order to improved the resolution of JADE estimator in coherent path environment, a temporal smoothing technique is introduced and analyzed. Finally, the projection approximation subspace tracking technique is applied in tracking a moving target in multipath environment. The techniques and analysis in the book can be useful to researchers in the fields of radiolocation, direction finding and TOA estimation in wireless...Похожие книги
