Abstract: The sparse array could reduce the cost of physical antennas. However, implementing wideband beamforming directly based on the covariance matrix of the received signals from the sparse array ...
Abstract: The Zak transform can directly map signals from the delay-Doppler domain to the time domain, which has a relatively low complexity for orthogonal time frequency space (OTFS) signal ...
Researchers at Tsinghua University and Z.ai built IndexCache to eliminate redundant computation in sparse attention models like DeepSeek and GLM. The training-free technique cuts 75% of indexer ...
Figures 12-14 are the land use/land cover maps of existing forest reserves in the FCT, namely; Tufa in Abaji, Chihuma, Chikwei, Kusoru and Shaba in Bwari, Maje Abuchi in Gwagwalada, then, Buga Hill, ...
Just because you have antivirus software installed on your PC doesn't mean a zero-day Trojan can't steal your personal data. The top encryption software keeps you safe from malware (and the NSA). When ...
Generic LIFO structure. Interview staple for parentheses validation, expression evaluation, and iterative DFS. Singly linked list with reverse, cycle detection (Floyd's), and middle-node finding (slow ...
