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…
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…
