Infrared Uplink Implementation for Software Defined Visible Light Communication Systems

by Oswaldo René Banda-Sayco

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 127–132, 2020; DOI: 10.25046/aj050614

Abstract:

The main advantage of software-defined visible light communication (VLC) systems is that they allow us to reuse modulation, coding, synchronization and medium access techniques used in conventional radio systems. This article focuses on the implementation of an uplink alternative using an infrared (IR) light communication system. For this goal, analog front-ends are designed and implemented.…

Over-The-Air Testing of Automotive Antennas and Wireless Links in The Installed State on The Basis of LTE Downlink Communication Parameters

by Philipp Berlt, Lisa Jäger, Andreas Schwind, Frank Wollenschläger, Christian Bornkessel and Matthias A. Hein

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 1, Page # 282–291, 2019; DOI: 10.25046/aj040127

Abstract:

Modern automobiles have been turning more and more into wireless sensor and communication networks. Accordingly, the number of radio systems is steadily increasing. Due to strict safety requirements, these radio systems need to be tested extensively for functionality and reliability, especially under poor radio channel conditions. Beside the large electrical size of cars at frequencies…
