A Versatile Spectrum Shaping Scheme for Communicating Beyond Notches in Multi-Drop Interfaces”
Mohammad Amin Shokrollahi, Seyed Armin Tajalli, Christoph Walter, Ali Hormati, Kiarash Gharibdoust
This paper proposes a signal shaping technique to increase the data rate of high-speed SerDes communication systems over multi-drop bus interfaces. This scenario creates a channel with deep notches in its spectrum, and therefore the effective data rate in ...
2016CSMA/CA in Time and Frequency Domains
Patrick Thiran, Julien Pierre Sacha Herzen
It has recently been shown that flexible channelization, whereby wireless stations adapt their spectrum bands on a per-frame basis, is feasible in practice. In this paper, we propose TF-CSMA/CA, an algorithm for flexible channelization that schedules packe ...
IEEE2015SAW: Spectrum Assignment for WLANs
Patrick Thiran, Julien Pierre Sacha Herzen, Ruben Merz
We consider the problem of jointly allocating channel center-frequencies and bandwidths for IEEE 802.11 wireless LANs (WLANs). The bandwidth used on a link significantly affects both the capacity experienced on this link and the interference produced on ne ...
2013Charge collection in amorphous silicon solar cells: Cell analysis and simulation of high-efficiency pin devices
Christophe Ballif, Matthieu Despeisse, Michael Elias Stückelberger, Yannick Samuel Riesen, Brice Perruche
The drift length Ldrift=μτE within the i layer of a-Si:H solar cells is a crucial parameter for charge collection and efficiency. It is strongly reduced not only by light-induced reduction of μτ, but also by electric field deformation ΔE by charges near th ...
