Then we propose an FDBF and illumination pattern random search (FDBF-IPRS) scheme to optimize illumination patterns and fully-digital beamformers using constrained random search and fractional programming methods.

2021年10月26日 · In this work, we introduce compressed Fourier domain convolutional beamforming, combining Fourier domain beamforming (FDBF), sparse convolutional beamforming, and compressed sensing methods. This allows reducing both the number of array elements and the sampling rate in each element while achieving high-resolution images.

What's the impact of windowing if FDBF is used? Figure 1 shows an acoustic map (TDBF) containing two loudspeakers, which transmit time-shifted impulse signals. Figure 2 shows an acouctic map computed with FDBF but under the same conditions as in time domain (0-96 kHz).

2024年10月1日 · In this article, a single-board integrated millimeter-wave (mm-Wave) asymmetric full-digital beamforming (AFDBF) array is developed for beyond-fifth-generation (B5G) and sixth-generation (6G) communications.

2018年7月16日 · In this work, we extend the recently proposed frequency-domain beamforming (FDBF) framework to plane-wave imaging. Beamforming in frequency yields the same image quality while using fewer samples. It achieves at least fourfold sampling and processing rate reduction by avoiding oversampling required by standard processing.

How does Delay-and-Sum Beamforming in the Frequency Domain work? The Delay-and-Sum Beamformer in frequency domain is based on a similar principle as in time domain. The block diagram in Figure 1 illustrates the case of two point sources situated in a measurement plane in front of the microphone array.
