The user experience on watching live videos transmitted by Unmanned Aerial Vehicles (UAVs) must be satisfactory even under the influence of topology changes caused by UAVs mobility on a Flying Ad-Hoc Networks (FANETs). However, one of the main challenges to route packets in FANETs is how to mitigate the effects of UAV mobility to preclude communication(More)
In this paper we design and implement a complex Digital Up-Converter (DUC) using a Xilinx Virtex6 FPGA. All the steps necessary to build such circuits are thoroughly described and some valuable hints on how to overcome problems during the design time are presented. We introduce a new approach for oscillator circuits, which are an important part of any DUC(More)
