Abstract: Cell-free techniques and unsourced random access (URA) are promising solutions for accommodating massive numbers of users. However, varying transmission distances between users and access ...

In Windows 11, you can create multiple partitions on a hard drive. If a hard drive partition has more free space and you want to create a separate partition from that, you can do so by shrinking the ...

Abstract: The problem of uplink transmissions in massive connectivity is commonly dealt with using schemes for grant-free random access. When a large number of devices transmit almost synchronously, ...

Encryption systems rely on “random” numbers, but conventional computers can’t generate them perfectly. New research shows that quantum physics can. By Alexander Nazaryan Researchers in Switzerland ...
