Experimental Demonstration of BLE Transmitter Positioning Based on AOA Estimation [PDF]
2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018 The introduction of the Bluetooth Low Energy (BLE) standard significantly streamlines the development of the Internet of Things (IoT) applications. These applications often require the sensor positioning to link the measurements with its location. Therefore, it is essential to conduct studies on BLE transmitter positioning methods. Power fingerprinting

GPS AOA estimation based on a modified despreader
2009 Conference Record of the Forty-Third Asilomar Conference on Signals, Systems and Computers, 2009The Global Positioning System (GPS) is designed to estimate the locations of users or objects, and has a variety of civilian and military applications. Although angles-of-arrival (AOAs) may be required to enhance the desired GPS signals, it is difficult to estimate explicit AOA information because a GPS signal has a low power relative to the noise ...

AOA Estimation by TDOA in an Outdoor Mutipath Environment
2007 IEEE 15th Signal Processing and Communications Applications, 2007This paper investigates the effects of multipath channel on angle of arrival (AOA) estimation with cross correlation time difference of arrival (TDOA) method. System model of a direction finding system that uses TDOA cross correlation method is presented.

Adaptive AoA and Polarization Estimation for Receiving Polarized mmWave Signals
IEEE Wireless Communications Letters, 2019This letter proposes a novel hybrid dual-polarized antenna array which exploits two orthogonally collocated dipoles to capture the full power of a polarized millimeter wave signal. To maximize the received signal-to-noise ratio (SNR), we study the adaptive angle-of-arrival and polarization state estimation, and develop a differential beam tracking ...

Enhanced AoA Estimation and Localization Through Transmitter Precoder Design
International Journal of Wireless Information Networks, 2012We propose a novel algorithm to improve the accuracy in estimating the angle-of-arrival (AoA) when the MUSIC (MUltiple SIgnal Classification) algorithm is used. An optimal precoder, with the objective to minimize the estimation errors of the AoAs, is first derived.

Joint compressed estimation of delay-AOA information for MIMO channels
2011 IEEE GLOBECOM Workshops (GC Wkshps), 2011Multiple-Input Multiple-Output(MIMO), one of the key techniques for next generation mobile communication systems, greatly enhance the frequency spectrum efficiency but also cause huge challenge on the accurate MIMO channel estimation due to the greatly increased channel parameters in time-, frequency-, and space-domain.

Joint AoD, AoA, and Channel Estimation for MIMO-OFDM Systems
IEEE Transactions on Vehicular Technology, 2018Beamforming with antenna arrays has been considered as an enabling technology in future wireless communication systems. To conduct beamforming, one has to know the angle-of-departure (AoD) or angle-of-arrival (AoA). For data detection, the receiver also has to know channel response. In this paper, we propose a new joint AoD, AoA, and channel estimation

TARGET: A direct AOA-TDOA estimation for blind broadband geolocalization
2015 23rd European Signal Processing Conference (EUSIPCO), 2015In this paper, a new robust and low computationally algorithm is proposed for broadband geolocalization. Recent work have demonstrated the superiority of the geolocalization in 1-step over the 2-steps algorithms. However this superiority is ob tained at the price of a bandwidth slicing which is unfor tunately limited for computational reasons and leads

Angle of arrival (AoA) estimation by using software defined radios
2016 24th Signal Processing and Communication Application Conference (SIU), 2016Source direction of arrival (DoA) or angle of arrival (AoA) estimation is one of the vital problems in many wireless communication applications such as radar, radio astronomy, sonar and navigation. The resolution of a source direction of arrival estimation can be improved by an uniform linear array (ULA) system with innovative signal processing ...
