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 ...

So, you’ve got a HackerRank test coming up, huh? It’s pretty common these days, with lots of companies using it to see if you can code. It can feel a bit daunting, but honestly, it’s just another ...

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) ...

HackerRank is a tech company that focuses on competitive programming challenges for both consumers and businesses, where developers compete by trying to program according to provided specifications.

As I'm beginning to integrate the sparse knn C++ layer w/ the existing (dense) nearest neighbors Python layer, I'm quickly seeing a need for a sparse cuml array. It would be great to have a container ...
