Communications and Control for Wireless Drone-Based Antenna Array
In this paper, the effective use of multiple quadrotor drones as an aerial antenna array that provides wireless service to ground users is investigated. In particular, under the goal of minimizing the airborne service time needed for communicating with ground users, a novel framework for deploying and operating a drone-based antenna array system whose elements are single-antenna drones is propo...
متن کاملDielectric Embedded ESPAR (DE-ESPAR) Antenna Array for Wireless Communications
A novel dielectric embedded electronically steerable passive array radiator (ESPAR) (DE-ESPAR) antenna array for mobile wireless communication terminal is developed by finite element method based numerical modeling technique. The size reduction of the seven-element monopole antenna was accomplished by embedding the array in a cylindrical rod of FIK ceramic complex with a relative permittivity a...
متن کاملSecure Precise Wireless Transmission with Random-Subcarrier-Selection-based Directional Modulation Transmit Antenna Array
In this paper, a practical wireless transmission scheme is proposed to transmit confidential messages to the desired user securely and precisely by the joint use of multiple tools including artificial noise (AN) projection, phase alignment (PA)/beamforming, and random subcarrier selection (RSCS) based on OFDM, and directional modulation (DM), short for RSCS-OFDM-DM. This RSCS-OFDM-DM scheme pro...
متن کاملFPGA-Based Communications Receivers for Smart Antenna Array Embedded Systems
Field-programmable gate arrays (FPGAs) are drawing ever increasing interest from designers of embedded wireless communications systems. They outpace digital signal processors (DSPs), through hardware execution of a wide range of parallelizable communications transceiver algorithms, at a fraction of the design and implementation effort and cost required for application-specific integrated circui...
متن کاملNew Antenna Array Architectures for Satellite Communications
Ground stations which integrate the control segment of a satellite mission have as a common feature, the use of large reflector antennas for space communication. Apart from many advantages, large dishes pose a number of impairments regarding their mechanical complexity, low flexibility, and high operation and maintenance costs. hus, reflector antennas are expensive and require the installation ...
