Performance analysis of joint DOA/TOA estimator
نویسندگان
چکیده
In many applications such as radar and mobile communication, the multipath propagation e5ects are described as a sum of contributions of a large number of wavefronts that arrives at the sensor array in clusters of rays, distributed around a nominal direction of the signal sources. Based on this observation and on the work of Bengtsson and Ottersten (Proceeding of Norsig-98, IEEE Nordic Signal Processing Symposium, April 1998), this paper jointly estimate the directions of arrival and the times of arrival of scattered sources. A theoretical performance analysis is given in terms of asymptotic error variance and illustrated by a simulation study. ? 2004 Elsevier B.V. All rights reserved.

Defending Against DDoS Attacks in Bloom Filter based Multicasting
Bloom filter (BF) based forwarding is an effective approach to implement scalable multicasting in distributed systems. The forwarding BF carried by each packet can encode either multicast tree or destination IP addresses, which are termed as tree oriented approach (TOA) and destination oriented approach (DOA), respectively. Recent studies have indicated that TOA based protocols have serious vul...
متن کاملComparison of Semidistributed Multinode TOA-DOA Fusion Localization and GPS-Aided TOA (DOA) Fusion Localization for MANETs
This paper evaluates the performance of a semidistributed multinode time-of-arrival (TOA) and direction-of-arrival (DOA) fusion localization technique in terms of localization circular error probability (CEP). The localization technique is applicable in mobile ad hoc networks (MANETs) when global positioning system (GPS) is not available (GPS denied environments). The localization CEP of the te...
متن کاملA New Algorithm for the Deinterleaving of Radar Pulses
This paper presents a new algorithm for the deinterleaving of radar signals, based on the direction of arrival (DOA), carrier frequency (RF), and time of arrival (TOA). The algorithm is applied to classic (constant), jitter, staggered, and dwell switch pulse repetition interval (PRI) signals. This algorithm consists of two stages. In the first stage, a Kohonen neural network clusters the receiv...
متن کاملJoint Toa/doa Based Geolocation System for Social Safety Robots
In this paper, we propose an efficient twodimensional geo-location system for social safety robots, where its location is obtained by direction of arrival (DOA) and time of arrival (TOA) of the radio signal of IEEE 802.11a. The proposed system requires only two reference signals while the conventional systems generally deploy more than three reference signals. For estimating TOA and DOA informa...

In this paper, performance analysis of hybrid localization based on radio-frequency (RF) and inertial measurement unit (IMU) measurements for a single wireless capsule endoscopy (WCE) traveling the gastrointestinal tract is studied. Specifically, the multiple bodymounted sensors are considered which are located on the front and back of a patient’s medical jacket and form the uniform rectangular...
