Cross Layer Energy-Efficiency Optimization For Cognitive Radio Transceivers
Andreas Peter Burg, Carl Christian Sten Dominic Senning
Designing energy-efficient cognitive radio transceivers requires joint optimization of medium access control and the physical layer implementation. In this paper we show an energy efficiency optimization strategy for IEEE 802.11n compliant transceivers in ...
IEEE2014On the MAC for Power-Line Communications: Modeling Assumptions and Performance Tradeoffs
Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou
Power-line communications are becoming a key component in home networking. The dominant MAC protocol for high data-rate power-line communications, IEEE 1901, employs a CSMA/CA mechanism similar to the backoff process of 802.11. Existing performance evaluat ...
2014Towards compact and frequency-tunable antenna solutions for MIMO transmission with a single RF chain
Julien Perruisseau-Carrier, Mohsen Yousefbeiki
Recently, a technique called beam-space MIMO has been demonstrated as an effective approach for transmitting multiple signals while using a single RF-chain. In this work, we present novel design considerations and a compact antenna solution to stimulate th ...
Institute of Electrical and Electronics Engineers2014Gaussian (dirty) multiple access channels: a compute-and-forward perspective
Michael Christoph Gastpar, Jingge Zhu
Lattice codes are applied to the two-user Gaussian multiple access channel (MAC) combined with a modified compute-and-forward transmitting scheme. It is shown that non-corner points on the boundary of the capacity region can be achieved by decoding two int ...
IEEE2014On Self-interference Suppression Methods for Low-complexity Full-duplex MIMO
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic, Konstantinos Alexandris
Full-duplex wireless communication offers improved spectral efficiency, as well as more efficient relaying and medium access, but requires suppression of self-interference. In this paper we analyze the existing methods for active RF suppression and use the ” ...
2013Pattern-reconfigurable built-in antenna for data multiplexing with a single radio
Julien Perruisseau-Carrier, Mohsen Yousefbeiki
Beam-space multiplexing has been demonstrated as a promising approach for transmitting multiple signals while using a single RF chain. This paper presents a novel beam-space antenna design that is very compact and integrated into a hypothetical portable pl ...
IEEE2013Physical-layer Network Coding on the Random-access Channel
Michael Christoph Gastpar, Jasper Goseling
We consider a physical-layer network coding strat- egy for the random-access channel, based on compute-and- forward. When packets collide, it is possible to reliably recover a linear combination of the packets at the receiver. Over many rounds of transmiss ...
2013Juxtaposed Color Halftoning Relying on Discrete Lines
Most halftoning techniques allow screen dots to overlap. They rely on the assumption that the inks are transparent, i.e. the inks do not scatter a significant portion of the light back to the air. However, many special effect inks such as metallic inks, ir ...
Ieee-Inst Electrical Electronics Engineers Inc2013Network Coding
The demand for higher throughput and better efficiency are two important challenges for future communication networks. During the past decades, a lot of research studies have been devoted to investigating and proposing near optimal and efficient schemes an ...
EPFL2012MIMO transmission using a single RF source: theory and antenna design
An approach for transmitting multiple signals using a single switched parasitic antenna (SPA) has been recently reported. The idea there is to map the signals to be transmitted onto a set of basis functions that serve as “virtual antennas” in the beamspace ...
