Abstract: Designing sparse arrays with fewer antenna elements and lower peak sidelobe level (PSLL) is critical and challenging for antenna arrays in terminal devices in Internet of Things (IoT) ...

Abstract: In a sparse array, the holes in the corresponding difference co-array (DCA) limit the length of the consecutive subarray, which in turn reduces the number of achievable uniform degrees of ...

The hottest trend in Olympic ice dance: Pretending to die How Super Bowl and TPUSA viewing figures compare House to vote on the SAVE America Act as GOP makes election bill push Something is happening ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Metasurfaces can help innovate traditional estimation algorithms as an excellent alternative to phased arrays. Direction of arrival (DoA) estimate is an important research area in array signal ...

I was wondering what your thoughts are for extending this to support sparse arrays? Scipy can perform the eigenvalue decomposition for sparse arrays and we could pass Jax BCOO or BCSR arrays to the ...

Instead of defining the types of underlying in-memory arrays, e.g. pointers_1_type and indices_0_type, consider defining the types of the in-memory sparse array as a whole. Consider the following spec ...
