When I got a 3D scanner, I only needed to calibrate it, and it was ready. Doing that wasn’t hard, as the scanner came with a ...

In this scenario, we jointly optimize the UAV's 3D trajectory and transmit power allocation to maximize the average secrecy rate during the whole communication period. To deal with the difficult joint ...

In this paper, we propose a joint DoA and TDoA estimation algorithm for mmWave communications. The key idea of proposed scheme is to use the pilot signal generated from the Zadoff-Chu sequence. Zadoff ...
