DOA estimation with hexagonal arrays
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002Hexagonal arrays are widely used in practice but have received less attention in the optimum array processing literature. In this paper, we show how unitary ESPRIT can be applied to hexagonal arrays for direction-of-arrival (DOA) estimation. The resulting estimates exhibit good threshold behavior, and are close to the Cramer-Rao bound above threshold ...

In this paper we present a Linear Vector Quantization (LVQ) neural network approach to estimate Direction of Arrivals (DOA) of narrowband sources. It is shown that appropriately trained LVQ networks along with a specific postprocessing scheme can successfully be used for DOA estimation purposes. We take advantage of the execution speed of LVQ algorithm

This work addresses the problem of direction-of-arrival (DOA) estimation, where true DOAs are not on the sampling grid when sparse signal recovery concept is adopted. To estimate DOAs exploring its sparse property, a basis is usually required. However, off-grid issue persists even when a large basis is constructed.

Doa dalam Al-Qur’an: Studi terhadap Doa-Doa Para Nabi
Ikhlas : Jurnal Ilmiah Pendidikan IslamPrayer 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 ...

Array interpolation and DOA MSE reduction
IEEE Transactions on Signal Processing, 2005Interpolation or mapping of data from a given real array to data from a virtual array of more suitable geometry is well known in array signal processing. This operation allows arrays of any geometry to be used with fast direction-of-arrival (DOA) estimators designed for linear arrays. In an earlier companion paper , a first-order condition for zero DOA
