Improved OFDM Signal Cancellation through Window Estimation

Autor: Chew, Daniel, Berhanu, Samuel, Baumgart, Chris, Cooper, A. Brinton

The ability to cancel an OFDM signal is important to many wireless communication systems including Power-Domain Non-orthogonal Multiple Access (PD-NOMA), Rate-Splitting Multiple Access (RSMA), and spectrum underlay for dynamic spectrum access. In thi

Covert Communications through Imperfect Cancellation

Autor: Chew, Daniel, Nguyen, Christine, Berhanu, Samuel, Baumgart, Chris, Cooper, A. Brinton

We propose a method for covert communications using an IEEE 802.11 OFDM/QAM packet as a carrier. We show how to hide the covert message so that the transmitted signal does not violate the spectral mask specified by the standard, and we determine its

Validity of a Local Positioning System during Outdoor and Indoor Conditions for Team Sports

Autor: Alt, Prisca S., Baumgart, Christian, Ueberschär, Olaf, Freiwald, Jürgen, Hoppe, Matthias W.

This study aimed to compare the validity of a local positioning system (LPS) during outdoor and indoor conditions for team sports. The impact of different filtering techniques was also investigated. Five male team sport athletes (age: 27 ± 2 years;

Non-invasively measured central and peripheral factors of oxygen uptake differ between patients with chronic heart failure and healthy controls

Autor: Brochhagen, Joana, Coll Barroso, Michael Thomas, Baumgart, Christian, Freiwald, Jürgen, Hoppe, Matthias Wilhelm

Background: Maximum oxygen uptake is an established measurement of diagnosing chronic heart failure and underlies various central and peripheral factors. However, central and peripheral factors are little investigated, because they are usually measur
