Adaptive beam forming techniques dynamically adjust the array pattern to optimize some characteristic of the received signal. In beam scanning, a single main beam of an array is …

Planar arrays provide directional beams, symmetrical patterns with low side lobes, much higher directivity (narrow main beam) than that of their individual element. In principle, they can point …

cylindrical/circular arrays do not have mature beamforming designs like planar arrays. This report provides an overview of one method of transforming circular array beamforming to be similar …

The figure shows that the beamwidth and sidelobe levels of the synthesized pattern match the desired specifications. The following figures show the desired 3D pattern, the synthesized 3D …

Dec 17, 2018 · This pattern shows that with isotropic array elements it is possible to have a maximum gain of 8 on the linear scale (or 9 dB on the logarithmic scale), which is expected …

Apr 19, 2024 · Based on the tutorial for a linear array here, I've written the following code for a 6 microphone circular array. The array has a radius of 5cm. A beam pattern is generated but it …

May 7, 2019 · Modal beamforming for circular arrays is also referred to as the circular-harmonics-domain (CHD) beamforming, which is based on decomposing the sound field into a series of …

In this paper, for adaptive arrays using space divi-sion multiple access, the optimal radiation pattern design of smart antennas is developed based on the particle swarm optimization …

Fig. 3. Beam patterns for the RPA and the CCA arrays. an arbitrary sphere around the BS. This number is calculated by the maximum number of supported half-power beamwidths (HPBWs) …

Beamforming approach is used for every type of array assuming uniform and log-normal distributions for the interference amplitudes. Equal volume cylindrical or prism type arrays with …
