DOA(Direction of Arrival) with array antennas based on MOM
2010 IEEE Antennas and Propagation Society International Symposium, 2010It's an important issue that estimation of signal direction for radar or communication system. And it was researched for military and commercial. Generally, it's a method that estimate to direction of signal by use each signal of array sensors. It called to DOA(Direction Of Arrival). For basically, there are Beamforming, Capon, Linear-prediction method.

Direction of arrival (DOA) determination based on monopulse concepts
2000 Asia-Pacific Microwave Conference. Proceedings (Cat. No.00TH8522), 2002Monopulse is a classical radar technique of precise finding of a source or target. The concept can be used both in radar applications as well as in modern communication techniques. The information contained in antenna sidelobes normally disturbs the determination of DOA in the case of a classical monopulse system. The suitable combination of amplitude-

On direction-of-arrival (DoA) feedback and precoding for D2D assisted massive MIMO
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018Effective channel state information (CSI) feedback design is difficult for massive multiple-input multiple-output (MIMO) downlink transmissions in 5G frequency division duplexing (FDD) bands, where partial CSI could be directly exchanged between users through device-to-device (D2D) communications.

Direction-of-arrival methods (DOA) and time difference of arrival (TDOA) position location technique
Proceedings of the Twenty-Second National Radio Science Conference, 2005. NRSC 2005., 2005This paper provides a detailed overview of the various methods for estimation of direction-of-arrival (also called angle-of-arrival) of a radio signal using an antenna array. The array-based directional-of-arrival (DOA) estimation techniques considered here are broadly divided into two different types: conventional techniques, and subspace based ...

2020 17th Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 2020
The Terahertz (0.1-10 THz) band is envisioned to meet the rapid growth of wireless data rates. Achieving high beamforming gain and reduced hardware complexity, the array-of-subarrays (AoSA) hybrid beamforming is a promising technology to be adopted for THz communications.

Direction-of-arrival (DOA) estimation in the presence of array signal coupling
2011 8th International Conference on Information, Communications & Signal Processing, 2011Direction-of-arrival (DOA) estimation is an important function in array signal processing. Many DOA estimation algorithms have been proposed catering for different situations and accuracies requirements. Nevertheless, most of these algorithms were designed based on the assumption of using ideal array sensors such as antennas with no interaction between

Direction of Arrival (DOA) Estimation
2019The importance of DOA estimation in radar processing for automotive applications cannot be overstated. It forms the third component of the radar cube: range, velocity, and angle. In practice, DOA estimation is often complicated by the fact that there will be multiple and unknown number of source signals impinging on the receiver array at the same time,

Parallel wavelet transform based wideband Direction-Of-Arrival (DOA) on multicore/GPU
IEEE International Conference on Electro-Information Technology , EIT 2013, 2013In most of the signal processing applications, main interest is to obtain an accurate estimation of the Direction-Of-Arrival (DOA) of a received signal. Computation of Direction-Of-Arrival (DOA) based on Wavelet transform and other techniques are available in the literature. This work is an improved work of our previously parallel implementation of DOA.

Low complexity direction of arrival (DoA) estimation for 2D massive MIMO systems
2012 IEEE Globecom Workshops, 2012Mobile data traffic is expected to almost double every year from 2012 to 2016. In order to address the challenge, “massive MIMO” has been proposed as one of the enabling technologies to significantly increase the spectral-efficiency of a wireless system.
