Wideband AoA Estimation and Beamforming with Hybrid Antenna Array
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011High speed long range millimetre-wave (mm-wave) links can be achieved by using wideband hybrid antenna arrays of sub-arrays. However, conventional wideband angle-of-arrival (AoA) estimation and beamforming algorithms are not applicable to the wideband hybrid arrays due to the array architecture difference.

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 ...

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
