Comparison 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...

Performance analysis of joint DOA/TOA estimator

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 P...

Bayesian CRLB for hybrid ToA and DoA based wireless localization with anchor uncertainty

In this paper, we derive the Bayesian Cramér-Rao lower bound for three dimensional hybrid localization using time-of-arrival (ToA) and direction-of-arrival (DoA) types of measurements. Unlike previous works, we include the practical constraint that the anchor position is not known exactly but rather up to some error. The resulting bound can be used for error analysis of such a localization syst...

Fundamental Limits of TOA/DOA and Inertial Measurement Unit-Based Wireless Capsule Endoscopy Hybrid Localization

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...

Cramer Rao Bounds for Primary User Localization Using Hybrid Toa/doa Technique in Cognitive Radios

Cognitive Radio (CR) is of great interest to technologists because of significantly increasing the spectrum efficiency. The Secondary user (SU) which is the unlicensed user must constantly study the actions of Primary user (PU), which is the licensed user. The location information of PU can enable several key functions of CR networks, such as aiding spectrum policy enforcement, intelligent loca...
