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.

Performance enhancement of aperture antennas used for estimation of Direction of Arrival (DOA)
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014In this paper, we propose a method based on signal processing techniques to improve the performance of aperture antennas, such as a parabolic reflector, used to estimate the Direction of Arrival (DOA) of a signal. Three signal processing algorithms are investigated, including the correlation method, which is used to make an initial estimate of the ...

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

Comparison of conventional and subspace based algorithms to estimate Direction of Arrival (DOA)
2016 International Conference on Communication and Signal Processing (ICCSP), 2016The Direction of Arrival (DOA) technology and researches are evolving areas in array signal processing. Biomedicine, sonar, radar, seismology, astronomy communication and earthquake widely use this estimation. We receive an incoming wave by sensing an array or a set of arrays, this sensed wave can be processed to derive many related estimation ...

A Genetic Algorithm based solution to three dimensional Direction of Arrival (DOA) problem
2008 IEEE International Multitopic Conference, 2008Estimating Direction of Arrival (DOA) of a signal in three dimensional space is a procedure which is difficult to perform in a reverberant and noisy environment, yet it demands high degree of precision. One of the most reliable techniques under reverberant conditions is Multi-Sensor Steered Response Power with Phase Transform filter (SRP-PHAT) but it ...

Single Snapshot Direction of Arrival(DoA) Estimation Using Variant Min-Norm Method
2018 International Conference on Communication and Signal Processing (ICCSP), 2018High resolution algorithms for angle estimation is essential to achieve resolution of targets in radar systems. Major drawback of existing subspace based algorithms is that its performance gets degraded for reduced number of snapshots. When number of snapshot is less than number of sources, resolution offered by subspace based algorithms are very less.
