Prototypes of Using Directional Antenna for Railroad Crossing Safety Applications
Xiaofu Ma, Sayantan Guha, Junsung Choi +5
In this demonstration proposal, we present a prototype of a rapidly deployable and cost-effective railroad crossing early warning system integrated with the railway system. Specifi…
Analysis of directional antenna for railroad crossing safety applications
Xiaofu Ma, Sayantan Guha, Junsung Choi +5
A rapidly deployable and cost-effective railroad crossing early warning system integrated with the railway system is attractive due to its protection of the unmanned grade crossing…
5G-CORNET: Platform as a Service
Vuk Marojevic, Shem Kikamaze, Randall Nealy +1
Practical testing of the latest wireless communications standards requires the availability of flexible radio frequency hardware, networking and computing resources. We are providi…
A Digital Predistortion Scheme Exploiting Degrees-of-Freedom for Massive MIMO Systems
Miao Yao, Munawwar Sohul, Randall Nealy +2
The primary source of nonlinear distortion in wireless transmitters is the power amplifier (PA). Conventional digital predistortion (DPD) schemes use high-order polynomials to accu…
LTE Spectrum Sharing Research Testbed: Integrated Hardware, Software, Network and Data
Vuk Marojevic, Randall Nealy, Jeffrey H. Reed
This paper presents Virginia Tech's wireless testbed supporting research on long-term evolution (LTE) signaling and radio frequency (RF) spectrum coexistence. LTE is continuously r…
On the Co-existence of TD-LTE and Radar over 3.5 GHz Band: An Experimental Study
Jeffrey H. Reed, Andrew W. Clegg, Aditya V. Padaki +5
This paper presents a pioneering study based on a series of experiments on the operation of commercial Time-Division Long-Term Evolution (TD-LTE) systems in the presence of pulsed…
