In this paper, a new array synthesis approach is developed for the design of reconfigurable sparse arrays radiating sum and difference patterns. The proposed approach provides a significant reduction in the complexity of the beam forming network, which is fulfilled by reducing the number of antenna ...
Recently, sparse arrays, such as coprime array and nested array, have been considerably attractive to improve active and passive sensing in radar, navigation, under-water acoustics, and wireless communications. Sparse array signal processing provides a systematic framework for sparse sampling and array...
We employed additional rows in the crossbar arrays and identified the best matching units by directly calculating the similarities between the input vectors and the weight matrix in the hardware. Using the memristor-based SOM, we demonstrated data clustering, image processing and solved the traveling...
are discussed. Followed by that, deep learning algorithm implementations as systolic arrays catering to the needs of specific embedded applications are discussed. The architectural modifications addressing sparsematrix representationsand structural pruning to improve the data reuse in systolic arrays are discus...
using a wearable array. The microphone signals are then processed and transmitted to a remote listener where binaural reproduction is performed with headphones. Both the person with the wearable array and the listener are free to move their heads, denoted by the gray and red curved arrows, ...
Support for sparse matrix (in form of a sparse column matrix and dictionary of keys matrix) will be coming shortly.Dense TensorsThe *Dense tensor is the primary tensor and is represented by a singular flat array, regardless of dimensions. See the Design of *Dense section for more information...
and allows the watermark to be used as a registration mark [2]. The number of frames with unique marks is variable, up top.Each mark can be repeated as needed. Additionally, because of their low cross-correlation, multiple arrays can be embedded in the same frame, to increase the data ...
and frequent operations (OPs) in graph learning46,47. The matrix is stored as the conductance of the resistive memory array, where Ohm’s law and Kirchhoff’s current law physically govern multiplication and summation, respectively. As a result, the data are stored and processed in the same ...
due to their unique band structures, SWCNTs and ZnTPP create a barrier between their band, suppressing the recombination of photo-generated carriers. Therefore, the device can achieve PPC over a wide temperature range (77–400 K) without additional energy consumption. This characteristic was not...
3.1. Sparse array construction For the 2D Costas array, a sparse 2D ultrasound array with separate transmitters and receivers is first constructed by using positions obtained from a Costas matrix. For HAPI-codes, the amount of additional clutter generated due to the decoding of the codes decreases...
