Pelibatan Tuhan dalam Wacana Larangan Membuang Sampah: Antara Doa dan Sumpah Serapah
One of the main community problems related to rubbish is disposing of it carelessly. This fact then gave rise to various responses such as placing the no-littering signs conveyed through prayer and swearing.

Gridless DOA Estimation and Root-MUSIC for Non-Uniform Linear Arrays [PDF]
Gridless direction of arrival (DOA) estimation is addressed for a 1-D non-uniform array (NUA) of arbitrary geometry. Currently, gridless DOA estimation is solved via convex relaxation, and is applicable only to uniform linear arrays (ULA). The ULA sample

Cramer-Rao Bounds for Joint RSS/DoA-Based Primary-User Localization in Cognitive Radio Networks [PDF]
Knowledge about the location of licensed primary-users (PU) could enable several key features in cognitive radio (CR) networks including improved spatio-temporal sensing, intelligent location-aware routing, as well as aiding spectrum policy enforcement ...

The influence of random element displacement on DOA estimates obtained with (Khatri-Rao-)root-MUSIC [PDF]
Although a wide range of direction of arrival (DOA) estimation algorithms has been described for a diverse range of array configurations, no specific stochastic analysis framework has been established to assess the probability density function of the ...

Stochastic framework for evaluating the effect of displaced antenna elements on DOA estimation [PDF]
We establish a statistical framework for investigating the influence of correlated random displacements of antenna elements in a uniform circular antenna array (UCA) on the distribution of direction-of-arrival (DOA) estimates. More specifically, we apply

DOA Estimation in B5G/6G: Trends and Challenges
Direction-of-arrival (DOA) estimation is the preliminary stage of communication, localization, and sensing. Hence, it is a canonical task for next-generation wireless communications, namely beyond 5G (B5G) or 6G communication networks.

Low-Cost Beamforming and DOA Estimation Based on One-Bit Reconfigurable Intelligent Surface [PDF]
In this work, we consider the Direction-of-Arrival (DOA) estimation problem in a low-cost architecture where only one antenna as the receiver is aided by a reconfigurable intelligent surface (RIS).
