Enhancing GNU Radio for Run-Time Assembly of FPGA-Based Accelerators
Software defined radios (SDRs) have changed the paradigm of slowly designing custom radios, instead allowing designers to quickly iterate designs with a large range of functionality. With the help of environments like the open-source project, GNU Radio, a designer can prototype radios with greatly …

USAGE OF 5G IN UAV MISSIONS FOR ISR
… modules and fusing the antenna module and radio hardware. The result is a three-dimensional beam. The UAV itself can be used as a base station for the 5G network, so that all ground stations can be connected as the UAV continues its flight path. UAVs can also be used as aerial nodes in a …

Wideband RF Front End Daughterboard Based on the Motorola RFIC
The goal of software-defined radio (SDR) is to move the processing of radio signals from the analog domain to the digital domain — to use digital microchips instead of analog circuit components. Until faster, higher-precision analog-to-digital (ADCs) and digital-to-analog converters (DACs) become …

White RHINO: a low-cost communications radar hardware platform
… is a shortage of low-cost commercially available hardware platforms tailored for the application. In order to boost Whitespace-based Communications Radar application development, the White RHINO(Reconfigurable Hardware Interface for computation and radio) hardware platform was developed. It aims …
