Cascaded optical ring resonator-based optical beamforming networks can be used to optimize the signal power received by planes. This is essential for airplanes-sattelite communication as a solution for a high-speed internet access inside airplanes cabin. ... see more

El Beamforming es una técnica de comunicación inalámbrica utilizada en aplicaciones de telecomunicaciones, la cual se usa para separar una señal deseada de señales interferentes. Esta técnica aumenta el rango de cobertura y reduce el problema de interfere... see more

Pada dunia industri kebisingan merupakan hal yang wajib untuk dikendalikan. Identifikasi sumber bising adalah satu metode penting untuk mengoptimalkan emisi bising yang berasal dari area tersebut. Obyek penelitian ini adalah pada area steam turbine geared... see more

To improve the transmitting adaptive beamforming efficiency and performance of the shape maintenance for the mainlobe, analyzed existing adaptive pattern for beamforming.In this paper, the question that the main lobe of adaptive pattern will be distorted ... see more

This research puts forth an optimization- based analog beamforming scheme for millimeter-wave (mmWave) massive MIMO systems. Main aim is to optimize the combination of analog precoder / combiner matrices for the purpose of getting near-optimal performance... see more

This paper newly proposes a frequency domain backoff scheme dedicated to continuous beamforming space division multiple access (CB-SDMA) on massive antenna systems for wireless entrance (MAS-WE). The entrance base station (EBS) has individual base band si... see more

The paper presents wind tunnel experiments, supplemented with phased array microphone measurements, on 2D basic models of low-speed axial fan blade sections: a flat plate, a cambered plate, and a RAF6-E airfoil. It aims at documenting the establishment of... see more

Axial fans operate in large numbers, often in the close vicinity of humans, therefore reducing their noise is a primary concern. In this paper, beamforming is applied to get information about the location and strength of noise sources on the rotor. This i... see more

This paper summarizes a case study example on the methodology used for phased array microphone measurements in a realistic acoustic environment. A ducted fan rotor is measured in an environment, where structure born noise and aerodynamically generated noi... see more
