DOA Estimation in heteroscedastic noise

Signal Processing, 2019
The paper considers direction of arrival (DOA) estimation from long-term observations in a very noisy environment. The concern is to derive methods obtaining reasonable DOAs at very low SNR. The noise is assumed zero-mean Gaussian and its variance varies in time and space, causing stationary data models to fit poorly over long observation times ...

Sparse Bayesian Learning Using Generalized Double Pareto Prior for DOA Estimation

IEEE Signal Processing Letters, 2021
In this letter, we propose a novel sparse Bayesian learning (SBL) algorithm using Generalized Double Pareto (GDP) prior to enhance the performance of direction of arrival (DOA) estimation for complex signals.

Low-Complexity Deep-Learning-Based DOA Estimation for Hybrid Massive MIMO Systems With Uniform Circular Arrays

IEEE Wireless Communications Letters, 2020
This letter proposes a low-complexity deep-learning-based direction-of-arrival (DOA) estimation method for a hybrid massive multiple-input multiple-output (MIMO) system with a uniform circular array at the base station.

Practical DOA Estimation via a Network of DOA-Blind Sensors

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
We consider the problem of DOA (direction of arrival) estimation of an acoustic wavefront by a wireless sensor network (WSN) within the SENMA architecture (a mobile agent (MA) repeatedly polls the sensors lying inside its field of view). The sensors, which are random in number and location, are DOA-blind and simply emit a pulse train synchronized to ...

Doa dalam Al-Qur’an: Studi terhadap Doa-Doa Para Nabi

Ikhlas : Jurnal Ilmiah Pendidikan Islam
Prayer constitutes the essence of worship in Islam and serves as a profound expression of faith, resilience, and spiritual submission. This study aims to unveil the multifaceted dimensions of the prophets’ prayers in the Qur’an by integrating the adābi ijtimāʾī approach of Tafsir Al-Azhar (Buya Hamka) and the lughāwī approach of Tafsir al-Kashshāf ...
