We analyze the error performance of distributed space-time codes in a wireless system with multiple cooperating transmitters and a single receiver. Due to the distributed nature of the system, the transmitted signals are subject to different average path losses. As our analysis shows, this effect leads to reduced diversity gains. We explain this result on the basis of an interesting duality bet...

Micro-unmanned aerial vehicles (UAVs), also known as drones, have been recognized an emerging technology offering a plethora of applications touching various aspects our lives, such surveillance, agriculture, entertainment, and intelligent transportation systems (ITS). Furthermore, due to their low cost ability be fitted with transmitters, cameras, other on-board sensors, UAVs can seen potentia...
