Electri-Fi Your Data: Measuring and Combining Power-Line Communications with WiFi

Patrick Thiran, Christina Vlachou, Sébastien Christophe Henri

Power-line communication (PLC) is widely used as it offers high data-rates and forms a network over electrical wiring, an existing and ubiquitous infrastructure. PLC is increasingly being deployed in hybrid networks that combine multiple technologies, the ...

Second-Order Rate Region of Constant-Composition Codes for the Multiple-Access Channel

Jonathan Mark Scarlett, Albert Guillén i Fàbregas

This paper studies the second-order asymptotics of coding rates for the discrete memoryless multiple-access channel (MAC) with a fixed target error probability. Using constant-composition random coding, coded time-sharing, and a variant of Hoeffding's comb ...

Prioritized Random MAC Optimization via Graph-based Analysis

Pascal Frossard, Laura Toni

Motivated by the analogy between successive interference cancellation and iterative belief-propagation on erasure channels, irregular repetition slotted ALOHA (IRSA) strategies have received a lot of attention in the design of medium access control protoco ...

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 ...

Towards 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 ...

Gaussian (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 ...

Performance Analysis of MAC for Power-Line Communications

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

We investigate the IEEE 1901 MAC protocol, the dominant protocol for high data rate power-line communications. 1901 employs a CSMA/CA mechanism similar to – but much more complex than – the backoff mechanism of 802.11. Because of this extra complexity, and ...

Polar Codes for the Two-User Multiple-Access Channel

Emre Telatar, Eren Sasoglu

Arikan's polar coding method is extended to two-user multiple-access channels. It is shown that if the two users of the channel use Arikan's construction, the resulting channels will polarize to one of five possible extremals, on each of which uncoded tran ...

Physical-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 ...

Pattern-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 ...
