Angle of Arrival Estimation Using Cholesky Decomposition [PDF]

International Journal of Antennas and Propagation, 2012
An angle of arrival (AOA) estimator is presented. Many applications require accurate AOA estimates such as wireless positioning and signal enhancement using space-processing techniques. The proposed AOA estimator depends on the Cholesky decomposition of

Gaussian Channel Model for Mobile Multipath Environment

EURASIP Journal on Advances in Signal Processing, 2004
A model of an angle-spread source is described, termed the “Gaussian channel model” (GCM). This model is used to represent signals transmitted between a user equipment and a cellular base station.

Deep Learning Enabled Beam Tracking for Non-Line of Sight Millimeter Wave Communications

IEEE Open Journal of the Communications Society, 2021
To solve the complex beam alignment issue in non-line-of-sight (NLOS) millimeter wave communications, this paper presents a deep neural network (DNN) based procedure to predict the angle of arrival (AOA) and angle of departure (AOD) both in terms of ...

Impact of ENSO on Nitrous Oxide Emissions in the Eastern Tropical Pacific

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Nitrous oxide (N2O ${\mathrm{N}}_{2}\mathrm{O}$) is a powerful greenhouse gas, with the ocean contributing ∼4.2 Tg N y−1 to global N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions. The Eastern Tropical Pacific (ETP) is a hotspot of N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions due to high N2O ${\mathrm{N}}_{2}\mathrm{O}$ production under low‐oxygen ...

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

Localization using Angle-of-Arrival (AoA) Triangulation

Proceedings of the International Workshop on Environmental Sensing Systems for Smart Cities
Indoor localization is a long-standing challenge in mobile computing, with significant implications for enabling location-aware and intelligent applications within smart environments such as homes, offices, and retail spaces. As AI assistants such as Amazon Alexa and Google Nest become increasingly pervasive, microphone-equipped devices are emerging as

Channel Estimation For Mimo-Ofdm Systems of Joint Angle-of-Departure (AOD) or Angle-of-Arrival (AOA)

International Journal of Innovative Technology and Exploring Engineering, 2019
Beamforming with gathering mechanical assembly displays has been considered as an engaging advancement in future remote correspondence structures. To coordinate beamforming, one has to know the angle-of-departure (AoD) or angle-of-arrival (AoA). For data disclosure, the beneficiary in like manner has to know station response.

A Comparative Analysis of Intratesticular Versus Intra‐Epididymal Injections of Clove Essential Oil on Male Dog Sterilization

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study evaluated clove essential oil as a non‐surgical sterilant in male dogs. Both intratesticular and intra‐epididymal injections significantly reduced sperm concentration, motility and viability, with histological and sonographic evidence of reproductive tissue damage.
