Coexistence of Communication Systems based on Heterogeneous Waveforms in 5G Wireless Networks
Presenter: Quentin Bodinier Abstract: 5G networks are envisioned to accommodate a wide range of applications, from high throughput cellular communications to sparse transmissions of short packets for the Internet of things. To satisfy the ensuing surge in data rate demands, 5G networks will have to make the most of an already saturated spectrum. Whereas it is now proposed to exploit frequency bands above 6GHz, this talk will rather explore ways to optimally exploit already licensed bands that are not used…

Presenter: Ahmad Mahbubul Alam Abstract: Characterizing the energy efficiency-spectral efficiency (EE-SE) region considering the static circuit power consumption is becoming increasingly important. One of the used strategies to increase the SE of cellular network is to reuse the frequency bandwidth over relatively small areas. The major issue in this case is higher interference caused by the transmission on the same frequencies. We obtain a parametric expression of the interference to signal ratio with a curve fitting approach to study the…

Presenter: Vincent Gouldieff Abstract: The advent of cutting-edge telecommunications techniques, such as intelligent radio (CR), has resulted in an increasing need for blind signal processing methods (spectrum sensing, standard detection, constellation recognition, intrinsic parameter estimation of digital signals). In this context, so-called "cyclostationary" methods have been studied since the 1970s and have rapidly shown a clear advantage over "classical" methods. In this presentation, we first propose some didactic reminders on the theory of cyclostationary estimation. In a second part, we…
